Observations

The photos here were all taken at 20.92354° N, 99.56914°W. This location is very near the Ranas ruins, outside the town of San Joaquin in San Luis Potosí. There is a good paved road to the town and a good gravel road continuing to the prominently signed ruins. The area is also very good for Pinus montezumae and P. teocote.
