Every writer comes to the Colorado River in the Grand Canyon with a unique point of view. Ann Zwinger's is that of a naturalist, an "observer at the river's brim." Teamed with scientists and other volunteer naturalists, Zwinger was part of an ongoing study of change along the Colorado. In all seasons and all weathers, in almost every kind of craft that goes down the waves, she returned to the Grand Canyon again and again to explore, look, and listen. From the thrill of running the rapids to the wonder in a grain of sand, her words take the reader down 280 miles of the "ever-flowing, energetic, whooping and hollering, galloping" river. Zwinger's book begins with a bald eagle count at Nankoweap Creek in January and ends with a subzero, snowy walk out of the canyon at winter solstice. Between are the delights of spring in side canyons, the benediction of rain on a summer beach, and the chill that comes off limestone walls in November. Her eye for detail catches the enchantment of small things played against the immensity of the river: the gatling-gun love song of tree frogs; the fragile beauty of an evening primrose; ravens "always in close attendance, like lugubrious, sharp-eyed, nineteenth-century undertakers"; and a golden eagle chasing a trout "with wings akimbo like a cleaning lady after a cockroach." As she travels downstream, Zwinger follows others in history who have risked—and occasionally lost—their lives on the Colorado. Hiking in narrow canyons, she finds cliff dwellings and broken pottery of prehistoric Indians. Rounding a bend or running a rapid, she remembers the triumphs and tragedies of early explorers and pioneers. She describes the changes that have come with putting a big dam on a big river and how the dam has affected the riverine flora and fauna as well as the rapids and their future. Science in the hands of a poet, this captivating book is for armchair travelers who may never see the grandiose Colorado and for those who have run it wisely and well. Like the author, readers will find themselves bewitched by the color and flow of the river, and enticed by what's around the next bend. With her, they will find its rhythms still in the mind, long after the splash and spray and pound are gone.

Shipboard ADCP and CTD measurements were conducted in Monterey Submarine Canyon in April and October 1994 to determine the propagation characteristics and energy levels of the semidiurnal internal tide. The measurements reveal a bottom intensified internal tide propagating energy up canyon. The region of strongest motion is in a beam 150-200 m thick, centered approximately 150 m above the Canyon floor. Along canyon baroclinic M2 currents are typically 15-20 cm/s, an order of magnitude larger than the estimated barotropic tidal currents. In April 1994, the internal tidal beam is well described by a progressive wave, while in October 1994, the signal is standing along and perpendicular to the beam. The Princeton Ocean Model was used to study the generation and propagation of semidiurnal internal tides in submarine canyons and to investigate their sensitivity to canyon shape.

The Green River runs wild, free and vigourous from southern Wyoming to northeastern Utah. Edward Abbey wrote in these pages in 1975 that Anne Zwinger's account of the Green River and its subtle forms of life and nonlife may be taken as authoritative. 'Run, River, Run,' should serve as a standard reference work on this part of the American West for many years to come." —New York Times Book Review
