The first few photos in this, part 2 of the photographs from California, are carried over from Modoc National Forest. The remainder are mostly from Lava Beds National Monument, which is a unique place where visitors can actually explore caves formed by lava tubes from past volcanoes on their own. That's right, you and your flashlight; no tour guide. Underground, pitch blackness poses interesting photography challenges, but I'm pretty pleased with my no flash (to avoid starkly white photos), steady-handedness technique. The final few photographs, including the one of the petroglyph are from Petroglyph Point at the Lava Beds. Unfortunately, we were limited in our ability to get too close to the petroglyphs due to recent defacing of the rock and petroglyphs.
