F4 - that is cool; always impressive to see ospreys and other raptors interacting and active.
Clink - yeah, there are a couple different species of willows at Pinnacles. They are quite abundant along most of the more lush riparian corridors, especially the larger corridors like Sandy Creek (running through the campground), and Chalone Creek (along North and South Wilderness Trails, on Balconies Trail from Chaparral Parking Area, etc.). I established 4 new routes at a spot I called Wind Willow Rock, located a short ways out on the North Wilderness Trail from Old Pinnacles Trail - there are abundant willows and cottonwoods near the rock base.
