THIS HIKE HAS BEEN CANCELLED

Get an action-packed tour of the geology of Tiger Mountain in the seldom visited Grand Canyon of Fifteenmile Creek led by UW geologist, Dr. Will Hoover! On this 4.5-mile hike, you will learn about the uplift of the Issaquah Alps, local faults and how we track their activity, the ancient environment that produced the rocks of Tiger Mountain, and local coal mining and its environmental legacy. This is an interactive hike with hands-on observations, discussion and Q&A.
