Ok, you’re at Thacher Park, looking at rocks along the Indian Ladder Trail. Then you drive to Catskill—can you find the same rock layers there? Dr. Charles Ver Straeten will explain how correlation, or recognizing same-age rocks from place to place, is one of the elemental tasks of a sedimentary geologist. Correlating rocks is done by finding the same features or patterns at different places, such as the same unique fossils, unique layers, or patterns of sedimentation in rocks.
This program includes a 20-minute talk followed by brief Q&A. Participants are welcomed to bring their lunches.
