DEVIL’S SINKHOLE “BATS AND STARS” ATTRACTS 73 GUESTS
On Saturday, August 30, the volunteers and staff of the Devil’s Sinkhole State Natural Area welcomed 73 guests for the annual combination batwatch and stargazing night.
Guests included a four-year-old named George who had been studying sinkholes. He dropped in with his dad all the way from Colorado. A nice group of staff and volunteers from nearby Garner State Park also joined the throng.
While the population of bats in the Sinkhole is unusually low in number this year, everyone seemed to appreciate the program presented by the Devil’s Sinkhole Society.
The event usually attracts four or five astronomers from the terrific San Antonio Astronomical Association, but the Weather Channel and Accuweather scared away all but one Robert Sepp this year. The sky was half cloudy but half crystal clear. Sepp helped guests examine the two dippers and the moon very closely.
The Devil’s Sinkhole State Natural Area has a Bortle scale rating of 2, as good a dark sky as you can get in Texas without traveling to Big Bend National Park.
Four-year-old George, now a Junior Cave Scientist, reported that he had “seen the moon.”
The Devil’s Sinkhole Society operates the Rocksprings Visitors Center and, for the past 25 years, has provided tours to see the Devil’s Sinkhole National Natural Landmark, Texas’s biggest one-chamber cave, Texas’s fifth-deepest cave, and, normally, the summer home of Texas’s fourth-biggest bat colony.
Tours of the Devil’s Sinkhole are provided Wednesday through Sunday all year long with a few interruptions around Thanksgiving and Christmastime. Daytime tours, including nature walks and birding, are available at 10 A.M. and 1 P.M. The famous evening bat tour runs May through early November, with varying times dependent on changing bat habits.
The Devil’s Sinkhole Society volunteers who hosted the great group of guests were Sandra and Richard West, D.L. Somerville, Patti and Mike Saunders, Dennis and Benita Piper, Mike Cox, and Emma and Andrew Barnebey.
