The rapid expansion of natural gas development has raised concerns about potential effects of energy development for fish and wildlife. Oil and gas production and infrastructure have the potential to alter stream habitat conditions and aquatic communities. We have conducted research on the sensitivity of streams and their native fish species to energy development in the La Barge oil and gas field in southwest Wyoming. We found that aquatic habitat quality is altered by energy development and fish species varied in their sensitivity to energy development. Improved understanding of the effects of oil and gas development will allow more explicit management and mitigation recommendations for the protection of native fish communities.
Annika Walters is an applied aquatic ecologist with broad research interests in population and community ecology, fisheries, and conservation biology. She is the assistant unit leader for fisheries at the USGS Wyoming Cooperative Fish and Wildlife Research Unit and an assistant professor in the Zoology and Physiology department at the University of Wyoming. Prior to coming to Wyoming she was in Seattle where she did postdoctoral work at the NOAA Northwest Fisheries Science Center and University of Washington. She got her PhD in Ecology and Evolutionary Biology at Yale University.

Mighty Mountains: Deciphering the Geologic History of the Teton Range
Although in the 1870s members of the Hayden geological surveys of the territories had noted that the Teton peaks were composed of metamorphic rocks, nearly a century would pass before a geologic map was made of the range. This presentation describes how John C. Reed, Jr. of the U.S. Geological Survey produced the first geologic map of the Precambrian rocks that compose the Teton uplift. His project, which occupied six summers between 1962 and 1970, involved systematic inspection and description of every peak and canyon. In addition to his geologic map, Reed contributed the chapter on the geology of the Tetons to Ortenburger’s Climber’s Guide (in which a number of Reed’s pioneering routes and first ascents are documented) as well as co-authoring the popular book, “Creation of the Teton Landscape” for a general audience. The geologic framework that emerged from Reed’s map provided a springboard for more recent discoveries. Foremost among these is the recognition that the rocks of the Tetons record the oldest known Himalayan-style mountain building event on Earth, formed by a 2.7 billion-year old continent-continent collision.
John C. “Jack” Reed, Jr., is Scientist Emeritus at the U.S. Geological Survey. He earned his PhD at Johns Hopkins University in 1954, and started his life-long career with the U.S.G.S. in 1953. His most recent book, “Rocks above the Clouds” (2008), is the first geology book written for climbers and hikers of Colorado’s “14ers.”
Carol D. Frost is Professor of Geology at the University of Wyoming. She earned her PhD at the University of Cambridge in 1984, and has been on the faculty at UW since 1983. Her research interests include the evolution of the continental crust and the origin of granites, particularly in the ancient Wyoming Province that she considers the “nucleus of North America.”
