The mysterious megalithic-style circle of boulders on the western flanks of Mt. Tamalpais tend to trigger the curiosity of all those who visit. The location boasts sweeping views of the steep bald hillsides leading down to Stinson Beach and Bolinas Lagoon all the way to Ocean Beach in SF and beyond.
Although the scattered cloud cover seemed like it would make for a fantastic sunset, a thick haze over the ocean blocked most of the color and it wasn't until the Ranger came by and asked everyone to leave that a streak of pink appeared for one last picture.
I must say I'm always disappointed that they don't leave the gates open longer so that one can enjoy the hour or two after sunset. On the other hand it's nice to give the wildlife some space and temporary human-free habitat.
