Inventories of rock falls and other types of landslides are valuable tools for improving understanding of these events. For example, detailed information on rock falls is critical for identifying mechanisms that trigger rock falls, for quantifying the susceptibility of different cliffs to rock falls, and for developing magnitude-frequency relations. Further, inventories can assist in quantifying t

To obtain subsurface geologic information about the alluvium in the Big Thompson River valley, S -wave refraction data were collected along three roads that cross the valley. The traveltimes were processed to estimate velocities and thicknesses for a layered-earth model; from these models, three cross sections of the river valley were constructed. The river valleys are covered by a layer of soil,
