It rained all last night. We paddled to the east side of Patterson Island for our first sampling spot. Here, we drilled core samples out of rocks that were embedded in a larger rock outcrop. Basically the meteor impact broke a lot of rocks. These rock pieces were shoved into other rocks. In the afternoon we paddled to DeLaute Island. Here we took samples from a rock dike. This dike had been part of an ancient feeder system to a volcano. Think of this as the underground part of a volcano, or the plumbing for a volcano.
