a few other people showed up. The guide was kind of goofy, but sweet. If we had to do it again, I think we'd just have done a self-guided walk. But we got to go down into the caves, and I don't like caves, so it was good to be there with someone who knew what was safe. I presume, anyway. That's HDR, btw. Capturing the dynamic range with one image is tough -- the sun is so bright, and the caves are so dark, there's just no other way, but the colors of the lichen and moss and weathering on the lava are exquisite. I was looking forward to doing some long exposures and light painting once we got inside.
