Summary

A total of 20 bulk sediment samples from four trenches along a west-facing fault scarp

near Ridgway, Colorado, were floated to recover organic fragments suitable for radiocarbon

analysis. Three detrital charcoal samples also were examined. These samples were recovered

from colluvium in the vertical trench walls. Botanic components and detrital charcoal were

identified, and potentially radiocarbon datable material was separated. Because many of the

samples will date the same event or horizon, four charcoal samples (one from each of the four

trenches) were selected for AMS radiocarbon analysis as initial test to check for consistency.

Based on the dates obtained from these four samples, three additional samples were selected

for AMS radiocarbon analysis.
