Another Dimension? Time Portal? Another Planet? What's at the Bottom of Mel's Hole?

Overview

On Mel Waters' property in the Manastash Ridge, west of Ellensburg, Washington, there is a hole in the ground that looks like a well -- but it's not a well. Like the owners of the property before him, Mel used the hole as a trash dump. His neighbors used it too. Garbage, broken appliances, old tires, everything went in the hole. After a while, Mel started to wonder: why doesn't it fill up? Then he started to notice other strange things about the hole.
