Geology of the Middle Fork of the Salmon River, Idaho
29 August – 4 September 2008 (7 days)
This trip has been rescheduled for 2009.
This seven-day trip is a fully outfitted expedition on the Middle Fork of the Salmon River traveling through the Impassable Canyon in the largest wilderness in the lower 48 states. The Middle Fork is considered a class 4 river and offers adventurers a great opportunity to experience the thrill of river rafting while learning about the geology of this secluded region.
The trip will focus on the geomorphology and hydrology of the Middle Fork of the Salmon River as they relate to historical and current geologic events. A brief overview of the long-term geologic history and bedrock geology of the region will provide a contextual background for the trip. Topics such as glacial, incision, and landslide history, fluvial deposition, terrace formation, sedimentation, and bedrock composition will be covered at one to two study sites each day that will provide participants an opportunity for discussion and interpretation of the landscape.

Matt has been guiding on the Middle Fork of the Salmon River since 1991. He and Grant Meyer studied the fluvial terraces along the Middle Fork in 1996/97. (Meyer, G.A., and Leidecker, M.E., 1999, (Fluvial terraces along the Middle Fork Salmon River, Idaho, and their relation to glaciation, landslide dams, and incision rates: A preliminary analysis and river-mile guide, in Hughes, S.S., and Thackray, G.D., eds., Guidebook to the Geology of Eastern Idaho) Since 1997 Leidecker has observed, and photographed a series of landslide events that have altered the river channel.
Grant is an Associate Professor in the Earth and Planetary Sciences Department at the University of New Mexico and the recipient of GSA's 1997 Kirk Bryan Award. His research and academic interests include the geomorphology of hill slopes and fluvial systems, climatic, tectonic, and environmental geomorphology, Quaternary geology, and ecosystems processes. Recently, Meyer has been researching climate change and the effects of Holocene fire regimes on geomorphology in central Idaho.
