What arrives with May and what happens to the cabin where Jason and Charlie have been staying?

May arrives, and with it comes the spring thaw. In this part of the world, spring comes in late May and eventually makes the river passable once more. Charlie and Hawthorn watch as the ice begins to rise and then recede along with melting water. The dam breaks twice, and before long, the cabin they had shared is completely underwater. Fortunately, the boys have the foresight to get out.
