Our boats drift on calm, foamy water next to massive bluffs

Detailed Description
The Green River in the Uinta basin is fairly flat, so it carries a lot of foam. The foam often follows the fastest part of the river, with is ties to the shape of the channel and the curve of the river. From this level, you can sense subltle changes in the plant like, flow speed, temperature, water clarity, and fauna. Behind, you can see the record of landscapes past, which are ever changing.
