Oregon’s only national park, a geological wonder, and one of the most awesome bike rides in the US: Crater Lake National Park.
And yes, it’s a lake inside a volcano. Not just that, but it’s the deepest lake in the United States, and one of the ten deepest in the world. And it is COLD.
This is already on my own computer screen. Grateful hat tip to Erik.
