Valley area of west-central Idaho. Results and discussion.
The sequence of glacial deposits near McCall, Idaho, previously assigned to the Pinedale and Bull Lake glaciations, contains deposits of four different ages. These ages are defined by multiple relative-age criteria, including weathering rinds, soil

A series of 75 non-bordered plots was used to measure surface erosion on granitic road cuts on forest roads in the mountains of Idaho. Erosion data were collected for 4 years following road construction. Both mass and surface erosion processes were

Ces Amérindiens de l’Idaho ont subi dès 1863 une forte rétractation de la superficie de la réserve qui leur avait été allouée par le gouvernement fédéral en 1855. L’A. examine, à travers une série d’entretiens et de rappels historiques, l’attitude

This study utilizes GIS modeling to determine if the location of 559 landslides in the 875 km2 catchment of the Middle Fork of the Payette River, Idaho, can be predicted based on topographic attributes and a wetness index generated by the DYNWET
of Montana, Wyoming, and Idaho; 2) paleoclimate simulations from general circulation models that incorporate changes in large-scale controls; and 3) present-day climatic regimes of the western United States.
