The Geology department rolled out of Williamsburg last weekend and headed straight to Virginia’s geographic centroid for a wide-ranging field trip. It was the spring semester version of the Geology departmental field trip that’s open to all and free to attend. As always, we were rolling deep with more than 45 of us spread across five vans.

The Gladstone Gladiators led the trip, they’re a remarkable group of five W&M seniors who’ve spent much of the past year unraveling the challenging geology of the Gladstone 7.5’ quadrangle. Last summer they completed two months of field work. During the academic year, they’ve refined their digital geologic map while characterizing the chemistry, petrography, and structure of the bedrock in the lab. They’ve also done some exciting geochronology, and they’ll be sharing their research results with a professional audience at a Geological Society of America meeting later this month.

On this bright February weekend, the Gladiators led an eager group of students and faculty across the Gladstone area to see the landscape and its underlying bedrock, they also touched upon the region’s human history with its linkages to the geology and environment. The Gladiators dialed it up a few notches, creating the first-ever W&M Geology field trip crossword puzzle (pdf)!

Our overnight respite was at James River State Park, a quiet and peaceful jewel in Virginia’s constellation of state parks. The park staff set up at late afternoon wagon ride followed by an early evening star-gazing extravaganza – with no clouds and a new moon, it was a spectacular event.
This field trip showcased new research done by William & Mary students – a year ago we had hypotheses about the geological history in this region. Our research grant from the U.S. Geological Survey enabled us to make a modern map and test those hypotheses. We’ve confirmed some of our hypotheses, and made unexpected discoveries that require new models for the tectonic evolution of the central Appalachians.
In the William & Mary Geology department, all of our majors complete an independent research-based senior thesis. Every year, our majors add new knowledge about the workings of the Earth and its environment. Some projects are academic while others are applied, yet they all serve as launching points for our students to successfully find jobs or move into the graduate school realm.
The Gladstone Gladiators all have job and graduate school offers, next year they’ll be scattered from Arizona to Wisconsin.

Student-led geology field trips are a celebration of the science done by William & Mary undergraduates. These trips also serve to illustrate what research is for younger students and showcase the research opportunities that lay ahead.
