Old timers Colorado River trip video collection
Collection
Identifier: A0718
Scope and Contents
The old timers Colorado River trip video collection (1994) consists of video recordings of an expedition down the Colorado River conducted by the USGS and veteran river runners designed to document changes to the river, its geology and its ecosystem in the years after the construction of the Glen Canyon Dam. This collection includes footage documenting the scientific changes along the Colorado River and in the Grand Canyon including shots of the river trip, group meetings at Northern Arizona University, and oral histories documenting the shifts and changes in rapids, beaches, flora and fauna.

Historical Note
In 1994 veteran river runners joined scientists from the United States Geological Survey (USGS) and a group of historians and archivists on an expedition down the Colorado River. The participants discussed and compared environmental and experiential changes before and after the construction of Glen Canyon Dam and documented their findings with photographs, rephotography to document environmental impacts, and oral histories detailing past experiences on the river.
The USGS's Robert H. Webb, Theodore S. Melis, and Richard A. Valdez noted lower water temperatures, fewer sediment-laden flows, sand bar erosion, invasion of non-native tamarisk trees, reduction in driftwood, development of marshes, increase in non-native fish at the expense of native fishes, and increase in water bird populations. Additionally, they found evidence suggesting increases in the frequency of debris flows in the Grand Canyon, decreases in bat populations, and higher swallow and bighorn sheep populations. Perhaps more significantly, the observations and experiences gained from the trip and interviews help offer additional perspectives for Colorado River management. (From the Cline Library).

Abstract
The old timers Colorado River trip video collection (1994) consists of video recordings of an expedition down the Colorado River designed to document changes to the river, its geology and its ecosystem in the years after the construction of the Glen Canyon Dam. Representatives of the United States Geological Survey (USGS) and veteran river guides were joined by historians and archivists. This collection includes footage of the river trip, group meetings at Northern Arizona University, and anecdotes by veteran river runners about past journeys and historic rapids.
