Josh took Monday off work and the three of us drove up to Newberry Caldera, the largest active caldera in North America. It's so large that it has two lakes, both great for fishing but here at East Lake the fish were jumping out of the water and Josh was jumping out of his skin. The water was so clear we could see them swimming around that rock.
We stopped at the massive obsidian flow. You can see part of it behind Ian and Josh but it wraps around and is also behind me. Signs were posted everywhere, Taking of Rocks is Prohibited.
Someone had left these two rocks on a bench. The pumice on the left weighed about six pounds and I have no idea what the obsidian on the right weighed because I couldn't budge it in the least. Josh lifted it and estimated the weight at about 60 pounds. I'm fine with not taking the rocks.
