Locations of sites used to assess hillslope conditions are labeled 1 through 15. Rain gage site is labeled IS-1. Letter B indicates location of summer of 1996 debris-flow deposits that originated in Gallesteo formation colluvium. Letter C marks the location of tributary in which a very fluid debris flow occurred in the summer of 1996. Letter D denotes the location of possible old debris-flow deposits on the canyon floor.
Letter E marks the location of fan deposits at the mouths of tributaries.
The northern-most fan contains dateable charcoal. Base from U.S. Geological Survey Frijoles and Cochiti Dam 7.5 quadrangles. In this system, each of the flow types defined represents a continuous range of properties within the sediment-water flow continuum, and the different types of flow are distinguished based on ranges of sediment concentration and rheologic behavior. The three major flow types are briefly described below.
