Very cool. Go further around the area and past the sign to find clouded obsidian. Photos are from just a little bit further in the area

Nice campgrounds but wouldn’t recommend if you are just going in a tent. You are bound to be surrounded by RVs and the engines and noise from them may prevent you from sleeping. The bathrooms were nice and mostly clean, they had plenty of warm water too. If you are looking to spend some time on the reservoir and have an RV then it’s great for you.
