Once again, from the Las Cruces BLM office pamphlet about the Prehistoric Trackways:

Marine fossils tell of times when the sea took over parts of the land and then receded leaving shells, corals and microscopic organisms behind in thick slabs of limestone. Multiple layers of petrified wood laid out and buried (some even burnt and turned into petrified charcoal) show a picture of violent weather causing blow downs [vegetation blown down by the wind]. Plant fossils display what the botanical environment was like. Miles of sites with tracks from tiny amphibians to large reptiles show where animals roamed, how they walked, and glimpses into their lives. Even insect and invertbrate tracks and burrows display pictures of ancient life."

Join the trek to the past this Saturday, August 18th, beginning at 8AM at the Trackways.
