Along the Pinta Trail running north-south west of Austin is a large pictograph site known as Paint Rock. Pictographs at Paint Rock may act as a solar calendar, marking solstice.

Listen to a Texas Public Radio interview with Gordon Houston, PhD candidate in archaeoastronomy, about the site:

Texas Public Radio article

• " .. Until recently the intricate symbols were thought to be static and not interacting with the environment. But this is no longer the case, for some pictographs near Paint Rock Texas, east of San Angelo have revealed their ancient secret. We now know some of these symbols mark the solar solstice and equinox with astonishing accuracy.."

The possibility that pictographs at Paint Rock may have been used as a solar calendar was first discussed in a paper from 1999 given to the American Astronomical Society in Austin, Texas, by R. Robert Robbins of the University of Texas Astronomy Department at Austin; click on link:
