Exploring Deception Island

January 31, 1994

We first walked along the beach to a small glacial river, where the runoff from the melting snow field on top of the island was trickling down into the bay. It was eroding the volcanic ash and stone bed, which made a fairly soft gravelly bed at least several feet deep along the beach. We noted a few of the atypical rocks that must have been flung out of the volcano when it erupted. These were reddish and had lots of air bubble holes in them, so they were ejected very quickly from the volcano, while the rest were slower probably.

We were visited by a scientist who was working nearby on the island. He was driving a three-wheel scooter vehicle, and was happy to talk to the visitors about his work and what he'd learned.

Then, we made our way up the hill at the middle of the bay to the ruins of the Chilean base. It was amazing what the volcano had done there. Most of the base was buried, but some was sticking out and was all torn up, broken, or burnt. The concrete supports were still standing, with metal rods sticking out and twisting up away from the concrete. There was a concrete doorway that had collapsed as a unit face-down on the ground. Metal beams were twisted out of shape, and all of the wood that filled in the structure was broken off about a foot or so from the supports, with what might have been burn marks along the edges.

From there, we walked down the center of the beach, avoiding the Site of Special Scientific Interest (SSSI) area, which was surrounding a pool of steaming water with lichens of algae growing on the nearby gravel. It's of special scientific interest because it will hopefully give some insight into the colonization process of fresh islands. In this case, this part of Deception Island is still considered "fresh" because of the recent volcanic eruptions, that totally renewed the upper layers of the island.
