It was a magical spot! I was unclear before: I created the map myself after following the verbal instructions to the springs given by a friend. These instructions reminded me of the sequence in The Electric Kool Aid Acid Test where Tom Wolfe is instructed to 'follow the road and turn left where the tarmac shines in the moonlight', only longer and more ambiguous. We got there just as night was falling and nearly skinned ourselves scrambling down a sheer rock face in the dusk. Exhausted, we had just long enough to snap up the tent and brew some dinner. That said, we did appreciate camping on a ledge overlooking the valley illuminated by a waxing moon. This is deep in the mountains of a natural park, therefore peaceful and scintillating with starlight.

However, dawn the following day we made our way back down to the spring and there we had a two hour bath in the waters. A camping luxury. Here in addition to the deepest warm pool, there's another which is fed only by cold water (our icy plunge pool) and a third lukewarm one fed by the other two. Not just a natural hot spring but a natural spa.
