Does obsidian show up near volcanoes?

So I’m eyeing a volcano here that’s open to the public and its surrounded by a lake. Would this be a good spot to look?

Ryan I know Obsidian is volcanic glass but I don't think all volcanoes have Obsidian. I'm certainly no expert though. Might be worth a visit though. Maybe you could find someone with more information about this specific volcano.
