Use this self-guided geology route sheet to follow major rock features, overlooks, and interpretive stops across the park.
The best geology walk is the one that makes the rest of the park look newly legible.
Stop 1: Visitor Center Cutaway |
Intro panels explain the broad geologic story before visitors head into the field and start seeing rock and landform changes for themselves. |
Stop 2: Sentinel Hill |
Look for basalt structure, drainage patterns, and weathered breaks that influence trail layout and slope stability. |
Stop 3: Lower Basin Deposits |
Sediments, glacial leftovers, and wetland edge deposits show how water and ice shaped the valley after the older rock framework was in place. |
