This report presents a field guide to debris flows along the Interstate 70 corridor in the Front Range of Colorado. The setting of the field-trip area is described, followed by a detailed road log that includes descriptions for each of 10 field-trip stops. Most of the stops are at fans adjacent to Interstate 70. Stop descriptions focus on the origins of fan deposits, radiocarbon dating and debris-flow recurrence intervals, debris-flow initiation process, drainage-basin morphology, and debris-flow hazards.
