Grant, Gordon E; Swanson, Frederick J.; Lewis, Sarah L. 2011. Evolution of volcanic landforms in the western Cascades. Corvallis, Oregon: Oregon State University; Bretz Club Field Trip, 30 p.
This field trip will focus on geomorphic and erosional processes in an older volcanic landscape (the Western Cascades). Drawing on over 50 years of research at the H.J. Andrews Experimental Forest and surrounding area, we will examine hillslope, small watershed, fluvial, and landscape-level processes over a range of timescales. The emphasis will be on how styles
and products of erosion of volcanic landscapes plus subsequent alteration by hydrothermal processes set the stage for long-term landform evolution. Stops include examples of small watersheds and their alluvial fans, debris flows, earthflow complexes, and fluvial systems. The discussion will complement Jon Major's Saturday talk on contemporary volcano erosion/geomorphology.
