The broad objective is to build up a detailed knowledge of the Early Cretaceous stratigraphy in the Tethyan realm. The approach will be systematic through the integration of basin reference sections, basin or platform control sections, biostratigraphic data, and sequence stratigraphy. Includes volcanic history, formation of tufa, and other information on the lake and its environs. Also contains information on historical and cultural aspects of the region. An exploration of the geology of Colorado through mini-fieldtrips.
Site contains pictures, information about the geology as well as a glossary, and links.
