The geohazards field trip...

this Saturday morning was chilly and rainy, but we braved the elements and managed to visit a number of interesting sites in the Spokane area related to mass wasting, stormwater management, stream bank erosion and meander migration.

This image was acquired on a previous field trip, but it illustrates a location where Hangman Creek is impinging on a high cut bank consisting of unconsolidated outburst flood deposits, triggering several slump failures in the 1990s (click to enlarge):
