Serpentine outcrops are interesting geologic formations, often home to unique assemblages of plant species. When we heard about a serpentine outcrop in Gillespe County, Texas, it sounded like a good excuse for a botanical road trip!

Gillespie County lies in the center of Texas, in the part of the state often refered to as the Edwards Plateau. The northeast corner of the county, however, is more properly part of the Llano Uplift. In this region, the native limestone has largely worn away to expose the metamorphic and igneous rocks below.

We went prepared to find some interesting and unusual plants. We weren't disappointed. While we didn't see anything terribly rare or startling, we did see a fantastic array of wildflowers, many of which we had not seen in the field before.

We invite you to share the beauty we found on a very special Saturday in April.

NOTE: The chapters contain a large number of images. The small images that appear with the text are in GIF format. JPEG format large images are called up by clicking on the small images. It is more efficient to set your viewer so that the text and GIF images contained in the chapter do not have to be reloaded when you return from viewing a blownup JPEG image. If you are using Netscape, go to Options, select Preferences, then Helper Applications and select "launch application" for image/jpeg.
