Default The Chasm

The Chasm is a BC provincial park just north of Clinton. You can see the layers of ancient lava from previous volcanic activity.

I've been there a couple times. Really cool, all the layers of ancient basalt flows, with layers of ancient forest floor trapped between them. I believe you can even see the remnants of trees in them.

I think the prevailing consensus on the formation of the chasm was the catastrophic draining of a large glacial lake of some sort, during the last ice age. Interesting, because you figure that would take hundreds if not thousands of years to form.

I think if you googled fraser plateau basalt flows you'd find a bunch of info on the topic.
