Interested in College in Alaska?

Trench Digging

I was interested in the different layers exposed by the utility workers. On top is a layer of organic material, below which is a relatively thick layer of volcanic ash and then what I believe to be glacial till. I imagine the glacial till goes down to bedrock, but I do not know how deep that might be.
