West of Austin about 30 miles. Very nice place—I can’t say anything about it that can’t be found elsewhere online, except that this was my second time there, and I hope not my last visit.

Here’s a panorama of the whole pool, in 3 layers of exposures. I will post separately on my method for creating this pic.

This is a shot of the underside of the rim, rotated 180º.
This pic was made from 4 exposures taken from 3 frames. The sky was hard to deal with, due to the time of day (11 minutes past noon) and the angle I was shooting from. Still not 100% happy with it, sub specie aeternitatis, but can accept it during this life . . .

Another multiple-exposure composite: for the pathway, ISO 100, f/11, 1/125th, and for the big rock, 1/20th sec.

The path to the pool is beautiful and sometimes steep. Could be dangerous for someone blindfolded or drunk.

The restroom building next to the parking lot. This last pic shows what happens to the flowers when you invert the Curves line for the A and B channels in LAB mode, and then mask off the rest of the picture.
