Geology: Marine Fossils, 9/17

Volcanic Formation of the San Juan Mountains – Continental Divide Trail Hike

Walk through Ponderous Pine meadows to a beautiful overlook of Pagosa Peak. During this hike, we’ll go off trail and climb to some ridge-forming limestone outcrops in the Mancos formation that contain marine fossils and numerous calcite crystals.  Learn why this area was covered by an inland sea for 30 million years during the Cretaceous period. 

This is an ~5 loop hike with approximately 450 ft of gentle elevation gain. With stops to discuss the geology of the area, you can expect a time commitment of 4 hours. Pack a lunch or snack as we will be taking a break from the overview stop.
