"The integers of language are sentences, and their organs are the parts of speech. Linguistic organization, then, consists in the differentiation of the parts of speech and the integration of the sentence."

"We have an unknown distance yet to run, an unknown river to explore. What falls there are, we know not; what rocks beset the channel, we know not; what walls rise over the river, we know not. Ah, well! we may conjecture many things. The men talk as cheerfully as ever; jests are bandied about freely this morning; but to me the cheer is somber and the jests are ghastly."

"In Ute the name for bear is "he seizes," or "the hugger." In this case the verb is used for the noun, and in so doing the Indian names the bear by predicating one of his characteristics. Thus noun and verb are undifferentiated."

"In the past, history has been devoted chiefly to the exploits of heroes and the story of wars; but history is now being speedily reorganized and rewritten upon a scientific basis, to exhibit the growth of culture in all its grand departments. History itself is now a science, and is no longer an art in which men exploit in rhetorical paragraphs."

"Many years have passed since the exploration, and those who were boys with me in the enterprise are—ah, most of them are dead, and the living are gray with age. Their bronzed, hardy, brave faces come before me as they appeared in the vigor of life; their lithe but powerful forms seem to move around me; and the memory of the men and their heroic deeds, the men and their generous acts, overwhelms me with a joy that seems almost a grief, for it starts a fountain of tears. I was a maimed man; my right arm was gone; and these brave men, these good men, never forgot it. In every danger my safety was their first care, and in every waking hour some kind service was rendered me, and they transfigured my misfortune into a boon."

"Realizing the difficulty of painting in word colors a land so strange, so wonderful, and so vast in its features, in the weakness of my descriptive powers I have sought refuge in graphic illustration."

"Scientific education is a training in mental integrity. All along the history of culture from savagery to modern civilization men have imagined what ought to be, and then have tried to prove it true. This is the very spirit of metaphysic philosophy. When the imagination is not disciplined by unrelenting facts, it invents falsehood, and, when error has thus been invented, the heavens and the earth are ransacked for its proof."

"In Seneca the north is "the sun never goes there," and this sentence may be used as adjective or noun; in such cases noun, adjective, verb, and adverb are found as one vocable or word, and the four parts of speech are undifferentiated."

"The mountain slopes...are covered with dense forests of pines and firs. The lakes are often fringed with beautiful aspens, and when the autumn winds come their golden leaves are carried over the landscape in clouds of resplendent sheen."

"In science nothing can be permanently accepted but that which is true, and whatever is accepted as true is challenged again and again. It is an axiom in science that no truth can be so sacred that it may not be questioned. When that which has been accepted as true has the least doubt thrown upon it, scientific men at once re-examine the subject. No opinion is sacred. “It ought to be” is never heard in scientific circles. "It seems to be" and "we think it is" is the modest language of scientific literature."

"Honest investigation is but the application of common sense to the solution of the unknown. Science does not wait on Genius, but is the companion of Industry."

"Scientific education is catholic; it embraces the whole field of human learning. No student can master all knowledge in the short years of his academic life, but a young man of ability and industry may reasonably hope to master the outlines of science, obtain a deep insight into the methods of scientific research, and at the same time secure an initiation into some one of the departments of science, in such a manner that he may fully appreciate the multitude of facts upon which scientific conclusions rest, and be prepared to enter the field of scientific research himself and make additions to the sum of human knowledge."

"The exploration was not made for adventure, but purely for scientific purposes, geographic and geologic, and I had no intention of writing an account of it, but only of recording the scientific results."

"On my return from the first exploration of the canyons of the Colorado, I found that...a story of disaster had been circulated, with many particulars of hardship and tragedy, so that it was currently believed throughout the United States that all the members of the party were lost save one. A good friend of mine had gathered a great number of obituary notices, and it was interesting and rather flattering to me to discover the high esteem in which I had been held by the people of the United States. In my supposed death I had attained to a glory which I fear my continued life has not fully vindicated."

"Indian nouns are extremely connotive; that is, the name does more than simply denote the thing to which it belongs; in denoting the object, it also assigns to it some quality or characteristic."

"The wonders of the Grand Canyon cannot be adequately represented in symbols of speech, nor by speech itself. The resources of the graphic art are taxed beyond their powers in attempting to portray its features. Language and illustration combined must fail. The elements that unite to make the Grand Canyon the most sublime spectacle in nature are multifarious and exceedingly diverse. The Cyclopean forms which result from the sculpture of tempests through ages too long for man to compute, are wrought into endless details, to describe which would be a task equal in magnitude to that of describing the stars of the heavens or the multitudinous beauties of the forest with its traceries of foliage presented by oak and pine and poplar, by beech and linden and hawthorn, by tulip and lily and rose, and by fern and moss and lichen. Besides the elements of form, there are elements of color, for here the colors of the heavens are rivaled by the colors of the rocks. The rainbow is not more replete with hues. But form and color do not exhaust all the divine qualities of the Grand Canyon. It is the land of music. The river thunders in perpetual roar, swelling in floods of music when the storm gods play upon the rocks and fading away in soft and low murmurs when the infinite blue of heaven is unveiled. With the melody of the great tide rising and falling, swelling and vanishing forever, other melodies are heard in the gorges of the lateral canyons, while the waters plunge in the rapids among the rocks or leap in great cataracts. Thus the Grand Canyon is a land of song. Mountains of music swell in the rivers, hills of music billow in the creeks, and meadows of music murmur in the rills that ripple over the rocks. Altogether it is a symphony of multitudinous melodies. All this is the music of waters. The adamant foundations of the earth have been wrought into a sublime harp, upon which the clouds of the heavens play with mighty tempests or with gentle showers.The glories and the beauties of form, color and sound unite in the Grand Canyon—forms unrivaled even by the mountains, colors that vie with sunsets, and sounds that span the diapason from tempest to tinkling raindrop, from cataract to bubbling fountain. But more, it is a vast district of country. Were it a valley plain it would make a State. It can be seen only in parts from hour to hour and from day to day and from week to week and from month to month. A year scarcely suffices to see it all. It has infinite variety, and no part is ever duplicated. Its colors, though many and complex, at any instant change with the ascending and declining sun; lights and shadows appear and vanish with the passing clouds, and the changing seasons mark their passage in changing colors. You cannot see the Grand Canyon in one view, as if it were a changeless spectacle from which a curtain might be lifted, but to see it you have to toil from month to month through its labyrinths. It is a region more difficult to traverse than the Alps or the Himalayas, but if strength and courage are sufficient for the task, by a year’s toil a concept of sublimity can be obtained, never again to be equaled on the hither side of Paradise."

"Possible ideas and thoughts are vast in number. A distinct word for every distinct idea and thought would require a vast vocabulary. The problem in language is to express many ideas and thoughts with comparatively few words."

"The verb is relatively of much greater importance in an Indian tongue than in a civilized language."

"The landscape everywhere, away from the river, is of rock—cliffs of rock, tables of rock, plateaus of rock, terraces of rock, crags of rock—ten thousand strangely carved forms; rocks everywhere, and no vegetation, no soil, no sand. In long, gentle curves the river winds about these rocks."

"Years of drought and famine come and years of flood and famine come, and the climate is not changed with dance, libation or prayer."

"On the walls, and back many miles into the country, numbers of monument-shaped buttes are observed. So we have a curious ensemble of wonderful features—carved walls, royal arches, glens, alcove gulches, mounds, and monuments. From which of these features shall we select a name? We decide to call it Glen Canyon."

"The history of the world is replete with illustrations to the effect that the greater the ignorance the greater the abomination of unconforming opinion, and the greater the knowledge the greater the charity for dissenting opinions."

"Economy in speech is the force by which its development has been accomplished, and it divides itself properly into economy of utterance and economy of thought. Economy of utterance has had to do with the phonic constitution of words; economy of thought has developed the sentence."

"Mainstream geology is founded upon enunciated by James Hutton (1726–1797) and Charles Lyell (1797–1875), who argued that, during unlimited expanses of time, the Earth has undergone slow, ceaseless change by processes we can observe in operation. In their view, we cannot call on any powers that are not natural to the globe, admit of any action of which we do not know the principle, nor allege extraordinary events to explain a common appearance. A , originating from outside the Earth, and wreaking change instantaneously. Such a process violates every tenet of uniformitarianism. Largely for this reason, hypotheses of impact origin for craters on the Earth and the moon were vigorously opposed for the better part of the past century. Space-age research now has established beyond doubt the authenticity of impact as a geologic process, but an abundance of evidence exists that a wide chasm still persists between the views of impact specialists and those of terrestrial geologists. A full realization of the ramifications of impact processes may have been delayed by the advent of , which engulfed the geological community in the late 1960s. Revolutionary as it appeared at that time, plate tectonics, which is envisioned as involving gradual changes generated by forces internal to the globe, fully conforms with uniformitarian principles. In contrast, impact processes, which have recently been cited to account for cataclysmic events such as massive tsunami deposits, incinerating wildfires, and global extinctions, carry genuinely revolutionary implications that are fatal to the uniformitarian principle itself."

"In August, 1933, at the in Chicago, was founded with an enrollment of 57 charter members and and as the first President and Secretary-Treasurer, respectively. Within five years, the Society had doubled in size, with members from the U.S.A. and ten other nations. Annual meetings were suspended during World War II (1942 through 1945) and when it reconvened in 1946 the members adopted the name “”. By that time personal and professional antagonisms had arisen that threatened to fragment the Society and led, in 1949, to the resignation of Nininger and his wife. Throughout the 1950s the Society was widely regarded as a small, disorganized and essentially moribund organization. Revitalization of the Society began in the early 1960s after the advent of the when the Society steadily gained members with expertise in , , , and , and impact dynamics."

"Since the opening of the , images from have enabled us to map the surfaces of all the rocky planets and in the Solar System, thus transforming them from astronomical to geological objects. This progression of geology from being a strictly to one that is planetary-wide has provided us with a wealth of information on the evolutionary histories of other bodies and has supplied valuable new insights on the Earth itself. We have learned, for example, that the , and that the Moon subsequently accreted largely from debris of . The airless, waterless Moon still preserves a record of the impact events that have scarred its surface from the time its crust first formed. The much larger, volcanic Earth underwent a similar bombardment but most of the evidence was lost during the earliest 550 million years or so that elapsed before its first surviving systems of crustal rocks formed. Therefore, we decipher Earth's earliest history by investigating the record on the Moon. Lunar samples collected by the of the USA and the of the former USSR linked the Earth and Moon by their oxygen isotopic compositions and enabled us to construct a timescale of lunar events keyed to dated samples. They also permitted us to identify certain meteorites as fragments of the lunar crust that were projected to the Earth by impacts on the Moon. Similarly, analyses of the Martian surface soils and atmosphere by the and s led to the identification of meteorite fragments ejected by hypervelocity impacts on Mars. Images of Mars displayed land-forms wrought in the past by voluminous floodwaters, similar to those of the long-controversial of Washington State, USA. The record on Mars confirmed catastrophic flooding as a significant geomorphic process on at least one other planet. The first views of the Earth photographed by the crew of gave us the concept of and heightened international concern for protection of the global environment."

"The excess of over loss to the is a surprisingly small percentage of the average precipitation. The average amount of water that falls as precipitation over the United States annually is 30 es. Of this total, 21 inches are returned to the atmosphere in the form of through the process of evaporation and transpiration from plants. The balance of 9 inches contributes to the maintenance of and the ."

"The evidence from and fossils indicates that , , and probably the other , are cylinders of slowly building on a sinking or ; has occurred in and younger time, and there were three major periods of emergence during which the coral rocks were weathered subaerially."

"Over a period of ten years, simultaneous measurement of storm rainfall and resulting during individual storms were made in small basins in the , California. By simple measurement, without any recording devices, data collected define a relation of basin lag time to drainage area. This lag time, expressed as time between center of mass of rainfall and center of mass of runoff, is a specific measure of some basin characteristics including the effect of . Using lag time relations, synthetic hydrography construction shows the effect of urbanization on peak discharge from a given storm. The method applied to one storm shows that urbanization increased the peak discharge by two fold."

"Throughout human history, people have settled disproportionately along rivers, relying on the rivers for , , fertile agricultural soils, , and food from aquatic and riparian organisms. People have also devoted a tremendous amount of time and energy to altering river processes and form. We are not unique in this respect: ecologists refer to various organisms, from to some species of , as s in recognition of the ability of these organisms to alter the surrounding environment. People are unique in the extent to and intensity with which we alter rivers. In many cases, river engineerings has unintended consequences, and effectively mitigating these consequences requires that we understand rivers in the broadest sense, as shapers and integrators of . once described rivers as the gutters down which flow the ruins of continents (Leopold et al., 1964). His father, Aldo Leopold, described the functioning of an ecosystem as a round river to emphasize the cycling of s and energy."

"... relatively few people are aware of how nineteenth- and twentieth-century patterns impacted the mountain rivers of the . When I moved to Colorado in 1989, I was impressed by the sparkling water of the mountain rivers, and I too assumed that these were natural, fully functional rivers. It was only after I began to read historical accounts of the Colorado and to examine the streams more closely that I realized how dramatically they had been altered. I began to think of them as virtual rivers, which had the appearance of natural rivers but had lost much of a natural river's ecosystem functions."

"Saving the Dammed is Ellen Wohl's homage to s, describing their unique engineering prowess, the wider environmental impacts they exert, and why we should care. Throughout the book, Wohl binds a lifetime of professional riverine experience, observations of her local beaver population, gray literature, and primary literature to convey the benefits of beavers and convince the reader why we need more beaver-modified ecosystems."

"My had developed a craving to have his own land to experiment with a new idea: '. We needed, he said, to find out what the original had been like in our area and what we could do to bring it back. That, and his desire to have a special place to hunt, led to his purchase in the mid-1930s of an abandoned farm along the , in the —"." He specifically chose the Shack land because of its isolation and because this farm was a land of impoverished soil that had become an agricultural failure. In his view this was sick land that needed restoration; it needed to see again the native species that once must have grown here. It was one instance of his larger vision of the countrywide importance of land health and fostering the community of life."

"The fate of rivers would evidently not be disregarded by Leopold’s watchful eye. In the late 1950s, he and W.B. Langbein initiated what came to be called the Vigil Network, consisting of sections in small s where natural changes would be recorded regularly. Some of these have been operating continuously for half a century, and similar schemes are in operation in Israel and Sweden. Just as productive were some of Leopold’s rafting expeditions down rivers for which he needed depth and velocity data. In 1965, he surveyed 450 km of the in this manner (and again many years later with his distinguished collaborator, the physicist, soldier, and desert explorer ). Besides feeding into the morphometric work, these investigations paved the way for a concerted attack on the problems of and , presaged in a joint study of flood control with T. Maddock Jr. in 1954 and developed with T. Dunne in 1978 and D.L. Rosgen in the 1980s."

"I often think about maps, because so much of what I do involves measurement. To explain features or processes, you must first describe them. In science the description must be precise and to be accepted, and this requires measurement."

"When one observes the many and great changes that have occurred in some s since the beginning of the , he is inclined to the belief that a longer period of time was involved than he had been led to believe. is an example where lakes of great depth once existed in a locality that is now a true desert. Segments of giant fans, some faulted, have been built out on the dried-up lake basin. Some large s on the surface are so deeply weathered that a hammer blow will reduce them to . We are rapidly learning that certain are much more rapid than we have been wont to believe. But only recently have s attempted to determine by actual measurement process rates formerly the subject of general reasoning or speculation. Such measurement programs have documented the fact that rates of landscape change are greater than had earlier been suspected."

"To better understand how far various grains were transported by wind, she and Allen Solomon (then at the ) set a network of pollen traps near and s in the to match the pollen rain with different . These data were used to develop a pollen-vegetation calibration that still informs studies in the region and beyond."

"Rivers are the great shapers of . Rivers transport supplied for hillslope and , in some cases controlling the gradient of the hillslopes (Burbank et al., 1996). As they incise or aggrade to maintain a consistent relationship with their base level, rivers create s that in turn influence local climate; provide travel corridors for animals and humans; and support aquatic and riparian ecosystems that contain some of the Earth's highest levels of biodiversity. ... Although the study of rivers is well-established, the great majority of investigators have worked on the lowland rivers where most people live. Mountain rivers began to receive increasing attention as a subset of rivers only during the last two decades of the twentieth century."

"The and its large tributaries historically hosted an extraordinary assemblage of large-river fish species. The , , , , and ) all have morphological adaptation for life in turbid, fast-flowing waters. Most of these species are now or as a result of flow regulation from s, s, and ."

"About the time I was trying to decide what kind of I wanted to be, I took a hike along the canyon of the in central Arizona. I remember looking at the s along the canyon and feeling a quiet pride—and wonder—that I now understood how those sandbars got there and why they were located exactly there. I've always had trouble turning back rather than following just one more bend of the river to see what's ahead. Contemplating those sandbars, I realized I could spend my life following the next bend and the one after that—and the choice was made. I like natural environments. Cities and rural areas, not so much. I also like to read history and biography and tend to make note of relevant river tidbits I come across, such as descriptions of big logjams or abundant beaver dams that travelers described a century ago on rivers that no longer have those features. And I enjoy traveling and seeing new natural places."

"Behind our house lay a and . Though only a few s, it constituted wilderness to me. Deer, fox, raccoon, s, s, and s inhabited the woods. From the saplings, I culled poles that I used to build s and s. I built a shelter each summer and experimented with , substituting ground beef for . Then, when I was sixteen, our town decided to join the metropolis. The woodland and marsh were obliterated, replaced with a shopping mall, a church, an apartment complex, and a sunken freeway. I could not have been more hurt if a family member had been attacked."

"(quote from p. 36)"

"The long winter nights were devoted by the to the ceremonies of their secret fraternities, exhorting their most benevolent gods; rain priests in retreat invoked their anthropic deities for rain to fructify the earth, and elders taught the youths, sitting attentively at their knees by the flickering firelight, the mysteries of their life and religion. Of all the secrets of their lives none is more strictly guarded or more carefully transmitted than the knowledge of healing. The "doctor" instructs in the lore of plants, and the relation of plants to man and beast."

"While it was generally observed by early travelers among the , that they employed plants for medicinal purposes, it was long believed, even by scientific students, that the practice of Indian doctors was purely . The late Dr. , however, declared from the beginning of his ethnological investigations that the Indians employed many plants of real value in medicine."

"The children are industrious and patient little creatures, the boys assisting their elders in farming and , and the girls performing their share of domestic duties. A marked trait is their loving-kindness and care for younger brothers and sisters. Every little girl has her own water vase as soon as she is old enough to accompany her mother to the river in capacity of assistant water-carrier, and thus they begin at a very early age to poise the vase, Egyptian fashion, on their heads."

"Whilst the old still occupied the , they were attacked by the to avenge the supposed death of a priest who had been sent among them as a missionary many years before. The priest, feeling himself entirely forgotten by his own people, had identified himself with those among whom he had dwell so long. Apprised of the approach of the hostile Spaniards, the Indians prepared to defend themselves with huge stones to be hurled among the enemy should they attempt to scale the mesa by the only practicable pathway up the almost perpendicular face of the cliff. But when the cause of the hostile demonstration became known to the Indians, the priest in the absence of paper on which to write, scraped a smooth and wrote upon it a message to the attacking party. The skin was fastened to a large stone and thrown down into the valley. Upon this information of the safety of the priest, the Spaniards retired, leaving the Indians undisturbed. This tradition is very similar to the account given in ’ ”Conquest of Mexico,” of 's attack upon , and this author states that "beyond doubt ancient Zuñi and Cibola were the same Pueblo.""

"Over my career, I have collaborated with dozens of excellent scientists from a variety of disciplines to conduct research projects that have achieved far more than any of us could have on our own."

"All of my research involves a combination of field experimentation, field observations and laboratory analysis, and is fundamentally interdisciplinary and collaborative."

"The ultimate goal of my research is to improve our knowledge of how changes in climate and land-use will affect forest ecosystems and water resources."

"I investigate how forest processes affect water flow dynamics and pathways in soil and streams, and conversely, how water flow paths affect ecological function in mountainous areas. This bridging of hydrology and ecosystem science is key to developing sustainable management of water resources."
