Geology Hike at Spring Lake Preserve

SMGA sponsored its first hike of 2010 on Saturday, February 27 at Spring Lake Preserve. Andy Grubbs, a local geologist who is quite familiar with our area, led 9 of us on a geology based tour of the area. Spring Lake has many layers of the Balcones faultline from Eagle-Ford down to Edwards Limestone. We noted the buds on the Mexican buckeye and the agarita and noted many blooms already popping out. It was a gorgeous early spring day with lots of bird serenade and, with Andy’s help, very enlightening. Thanks Dick McBride for the photos.

Who or what made this mighty big hole?
