As we turned into the preserve we were greeted by a park ranger holding a clipboard. She asked for the name on our reservation, a reservation we didn’t have. We attempted to feel out any sympathetic tendencies, but it became clear she was immune to our plight. Having myself found out about the pool through a Google search, I felt unqualified to lament the effects of industrialized tourism for too long. Beia suggested Perdenales Falls State Park a half hour away and we were off.
