Patterson and DeLaute Islands

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.
