I have done the Tanner, Beamer to Little Colorado, then Escalante Route and out Grandview. It was a magnificent week long trip.
Be forwarned the Tanner is steep and crueling if you go all the way to Tanner Rapids in a day, especially if you do it when the tempertures are half way warm.
If you stay at the saddle, be prepared to carry large quanities of water to sustain you through the night. There is no water available until you hit the river. The distance from the trailhead to the river is highly debated.
Also clip your toenails short as the top portion of the Tanner is very very steep and you may end up loosing your toenails months down the road.
As far as the pooper it is a solar powered self composting , without any walls surrounding it. It is a pooper where you can watch the world go by around you. I have a pic somewhere.
