From the summit towers area headed to the east end of the road where there's an auto barrier and trailhead for the Ridge Trail (next three pics). However, this time trail access was barred to hikers due to some kind of PG&E work. So back down the way I came up on the Summit Loop north (last five pix), shortly connecting with the Dairy Ravine and Eucalyptus Loop Trails, looping back to where I started.
Through the Meadow and back onto the Bog Trail, a small black-and-white snake was in the middle of the trail. He was in the process of eating a tiny bug.
On any of the Bog Trail's several benches, it's difficult to get back up: few people, no nasty smells, (mostly) warm sun, gentle breezes, birdsong, bees and butterflies.
