What kid doesn’t like a big pile of rocks? Especially obsidian, pumice and lava rock. It is on every map and marked on the road. Prepare to get dusty looking for snowflake obsidian.

I've never seen so much obsidian in my entire life. And such huge obsidian stones. As big as cars! If you're up for driving several miles on a dirt road in the mountains--some cars may not be up for it--go for this. When you get...More

Drove until my compact was overwhelmed with a road too rough. Beautiful surroundings and more obsidian than I've ever seen before.

Let me start by saying a low clearance vehicle is not recommended for the whole road, but you can reach a trailhead halfway down the road. The dome is a pile of rocks, but what a pile of rocks! Almost entirely obsidian of different colors,...More
