One of the guides for our trip, Walter Metzke, brought his Phantom 4 drone, which we were able to use to get some aerial footage of our field site. We were able to do this for the penitente field located around 5200m, because we spent some extra acclimation time there. In these videos, Adam has… Read More

Today, we move up to 4000m for another sample collection and to camp higher than any of Colorado’s mountians. This will continue our acclimation process to prepare for the higher altitudes to come.… Read More
