Big Bend Highlights
Big Bend National Park
The complex desert ecology and well-exposed bedrock formations provide the focus of study in Big Bend National Park. Field mapping of volcanic formations and igneous intrusions.like the laccolith exposed in the Grapevine Hills (below) provide a challenge in this starkly beautiful terrain. Surge deposits and lahars are testament to a dynamic and violent history of the region.
|The erosive power of water is demonstrated in the Pour-Off, a canyon and spillway carved by an intermittent river in Big Bend. Students climb over pyroclastic volcanics studded with large grey volcanic bombs.|
|At Ernst Tinaja, the students examine Cretaceous limestones deformed by Laramide mountain building. Its clear that Big Bend is an excellent place to learn structural geology firsthand.|
