Texas Caves (Louise Lindsey Merrick Natural Environment Series, No. 31)

Description:

"Texas has about three thousand known, explored caves, ranging in size from small crawlways to huge caverns. Most of these caves, however, are generally restricted to exploration by trained, experienced cavers, geologists, and biologists."--BOOK JACKET. "Texas Caves introduces this seldom-seen world, providing basic cave geology and biology, a description of the seven show caves that have been opened and developed for public visiting, and information on state speleological parks."--BOOK JACKET. "The text along with a hundred full-color and black-and-white photographs reveal the glories of Texas caves, "wild" as well as commercial, showing different types of cave formations, the creatures that live in them, and the people who explore them."--BOOK JACKET.
