I hiked the Mount Pilchuck trail a week ago and just published a field guide on the Northwest Geology Field Trip website and you’ll find it here. I was motivated by an email from long-time reader Wendy B. She hiked Pilchuck last fall and asked me about this ‘standing stone’ near the summit.
So I finally hiked Pilchuck to see if I could deduce an answer for Wendy. I think I did, its in hike description. Also of geologic interest is the rock itself, the fine-grained granite of the Pilchuck Stock and its sets of parallel joints. The hike is famous for its fabulous views from the summit lookout, as well as the atrocious road to the parking lot.
