The Warren Skaaren Environmental Learning Center (ELC) at Westcave opened to the public on the vernal equinox, March 22, 2003. The ELC functions as a visitor center and also offers much needed classroom space for the Preserve's public and school programs. The building is a model of sustainable building design including such features as ground-source heating cooling, a solar energy panel, and a rainwater harvesting system. Project architect Robert Jackson's remarkable work was recognized with a 2003 Merit Design Award from the Austin Chapter of the American Institute of Architects.

Integrated exhibits at the ELC illustrate how the forces and cycles of nature have interacted to create and sustain this unique sanctuary. The ancient elements-earth, water, air, fire-are used to explain Westcave's geology, water, weather, and energy and their connection to the Preserve's plants and animals.
