We entered Labyrinth Canyon today, leaving the mud hills of yesterday. South out of the town of Green River is the most geologically boring area one could imagine. Mile after mile of mud hills called the Mancos shale, a bentonitic clay and limestone layer put down during a stagnant marine environment. Another words a petrified swamp. The river then moved into the Morrison formation, another layer made up of muddy looking deteriorating shale and siltstone.

So most were understandably overjoyed when we came into the red sandstone cliffs of canyon.

Dinner tonight was a lasagna Dutch oven
