Well dead gumit, we camped ove a Lake Abiquiu a couple of summers ago and we’re in Cuba when I was reading this advisory:

Otherwise we really wanted to go there.
Went to Bandelier instead.
I agree with the website that people should be wary of GPS in an isolated area. A while back my wife used Mapquest for directions to Crested Butte and it sent her over a pretty scary road. Best to use an old fashioned highway map.
