Geology of the Rock Trail, Larrabee State Park

Tafoni Wall, striped by tree shadows, is a highlight of the Rock Trail.

I have posted a geology guide to Larrabee State Park’s new Rock Trail. Read the full guide here on the Northwest Geology Field Trips website. The out-and-back hike is just short of 2 miles, and the cliff exposures are perhaps the best in the Chuckanuts. The trail, built by prodigious efforts of over 100 volunteers, was profiled in the Bellingham Herald in February.

Red line marks the new Rock Trail. Contour interval is 20'. Note scale in lower left.
