Bodie Hills seemed a stretch at this point, so after consulting the map, I thought Obsidian Dome and Mammoth Lakes Scenic Loop would be our best nearby bets for day tripping. The unpaved road to Obsidian Dome is north of June Lake Junction about 1 1/2 miles west of Deadman Summit off Hwy. 395. En route, we detoured to Hartley Springs campground (elevation 8,400') on Forest Service Road 2S48. The 1-mile drive up the dirt road was narrow & bumpy, but when we arrived at the campground I was surprised to find that a few RVs actually made it there. The sites, 25 in total, are well spaced and forested/shaded with picnic tables and fire rings. Best of all, usage seemed light. Moreover, it's pet friendly, close to the headwaters of the Owens River tributaries, and there's no fee. I think we'll come back with our Winnebago ERA sometime soon.
After leaving Hartley Springs campground and rejoining Glass Flow Road, we drove about a quarter mile past the parking area for Obsidian Dome before turning back, as the road became narrower and more difficult to navigate beyond that juncture. There was only one other vehicle at the Obsidian Dome parking lot and that was great. We tried to chat with the husband-wife couple hiking around the dome, but Addy and Sasha were especially vociferous during our attempted conversation. I guess they were in their protective and/or flippy I just wanna bark mood...Obsidian Dome is a mile-long, 300 ft. high volcanic glass lava dome that's part of the Inyo Volcanic chain. The beautiful, albeit sharp, piles of obsidian rocks are a sight to behold and totally worth the offroad trip. On our way back to Convict Lake, we detoured off on Mammoth Lakes Scenic Loop through the town of Mammoth Lakes. Highlights along the drive were Showy Penstemon (Penstemon speciosus) and Leichtlin's Mariposa Lilies (Calochortus leichtlinii).
