"Washington Rocks!" Geology Hike with Chad Pritchard

Geology Hike

Guided Hike at Dishman Hills Natural Area with Geologist Chad Pritchard

Take a hike with Chad Pritchard, EWU geology professor and co-author of the book “Washington Rocks!” to chat about the forces that fractured the 100 to 50 million year old granitic rocks of the Deep Ravine area at Dishman Hills.  Then continue up to the ponds to talk about surface and groundwater. All along the way we can use geology to discuss how these amazing outcroppings of rocks formed in the earth’s crust, rapidly (in a geologic sense) brought to the Earth’s surface, and then scoured by Ice Age megafloods.

We will meet at 8602 E Appleway Ave at the dirt parking lot. The hike will be about 2.5 miles with some elevation. Please bring water and sturdy shoes, and consider wearing long pants as poison ivy is present along this trail. Please pre-register for this hike.
