Dig into the geology near the Red Town Trailhead on Cougar Mountain by joining geologist Tom Doe for this 3-mile exploratory hike. Learn about and see examples of what is right underfoot, including the major rock types, glacial history, and even the legacy of coal mining in the area (no actual digging will take place).

This will be an interactive hike with stops for observation, discussion and Q&A.

The last planned stop involves walking in a small creek that will be flowing. Please choose your footwear accordingly.

Registration required. No pets allowed.
