Brenda writes from Puerto Williams

We had some other geologists on board during this part of the trip. They were looking at bedrock geology and the formation of Cordillera Darwin. We continued our work at Pia and Holanda and got a look at Seno Garibaldi as well. The weather at Garibaldi was a little wet and it even snowed at sea level. But, when it cleared, it was spectacular! At Pia and Holanda, we continued our work mapping the moraines. It is fall now and the Nothofagus antarctica (beech) has turned a rusty orange. The contrast between it and the N. betuloides is very sharp because the latter is an evergreen and does not turn color. We're back in Puerto Williams right now to drop off the other geologists and to stock up for our longer trip around to the north side of the mountains.
