Geology of Colorado (Boulder Valley) - Field Trip #1, Stop #3: Fountain & Lyons Formations

Prev | Index For This Date | Next
Stop #3 (10:45 a.m.) - Lyons formation at top of hill beyond trees. Roadcut in foreground is a more modern debris flow. We know it's a debris flow because the larger rocks and boulders are on the top with the fine grained material below. This is common in debris flows and avalanches.
