Welcome to the blog for the Oberlin College Geomorphology Research Group. We are a diverse team of students working with Amanda Henck Schmidt on geomorphology questions. This blog is an archive of our thoughts about our research, field work travel notes, and student research projects. Amanda's home page is here.

Day 10 Dominica Keck Project

Today we split into 3 groups. The geomorphology group went to collect water and sediment samples from rivers while another group collected basalt samples and the final group surveyed the stratigraphy at Fond St. Jean. The group looking for basalts traveled northward and through the middle of the island to attempt to get to the south east, because the road leading directly to Petite Savane was destroyed in 2015 by tropical storm Erika. They found 2 outcrops of basalt on the side of the road and collected samples from one of the outcrops. Since the road into Petite Savane was closed, the group got out of the car and hiked to the outcrop to collect samples. The trail was muddy, but passed some cool cows.

The group that headed to Fond St. Jean spent the morning looking at the stratigraphy along the side of the road and collecting some samples of basaltic ejecta. This material is believed to be some of the most primitive lava deposited on the island. Back at Springfield, these samples were washed and separated from the dirt encasing them and then heated to dry. Different people then spent the rest of the day labeling, cutting down, and packing up samples to be shipped off later this week, as well as meeting with the project directors to discuss individual projects.
