I agree with Mike about the out-house at the hot springs. Education is the key to handling waste at the springs. This can be achieved through conversations, the hand-out Ron is developing, etc.
I have one correction though:
Mike wrote: "4.) ... Or would it be one like they have at Saline Valley Warm Springs, where a deep hole is dug and when filled, a new hole is dug and the outhouse is moved to the new hole and the old one filled in or capped with top soil? ... "
The NPS has closed/destroyed the historic out-houses at Saline Valley. They now have vault-type out-houses which the NPS built and must periodically come pump out. It's great that the waste is actually removed but I miss the scenic views and the graffati that the old out-houses had. Such a loss of art!
