Richard Ashmore leads students on geological field trip

Richard Ashmore, geology adjunct professor, recently led a group of San Jacinto College (SJC) students on a trip to McFadden Beach on the Bolivar Peninsula and Galveston Island. The class examined how climate change, human habitation, strong storms, and tropical cyclones have shaped and developed the upper Texas coast.

The field trip allowed students to act as geologists in collecting shell samples and beach sand near Winnie along a remnant of a beach ridge that formed 120,000 years ago. Students then viewed where the Trinity River empties into Galveston Bay and sampled 50,000 years old deltaic sediment from channels of the paleo-Trinity River, deposited as the coastline advanced seaward.
