Been a long time for comments on this puzzle. Thought it would be extremely hard to work but was much surprised how easy it was. Thank you for the help of making the pieces automatically fit in place once it is in the right spot.
It actually looks like it could be of Mt. St. Helen's in Washington state. Could be Spirit Lake at the bottom of that spot that looks like where the volcano blew.

You would think that living in the northwest I would have seen Mt. St. Helen's but I haven't, yet anyhow.
