Jimmy is a National Geographic Young Explorer working to understand how climate change has and will affect ice climbing in the Mount Washington Valley, New Hampshire, and how winter guiding will be affected by changing Northeastern winters. For the past two years, he’s worked winters as an ice climbing guide in New Hampshire, and summers as a guide on expeditions to Denali in Alaska. Jimmy holds a B.S. in Geoscience and Engineering Science from Tufts University (2012) and an M.S. in Earth Science from Dartmouth College (2014). His graduate work focused on the geochemistry of arsenic on mineral surfaces.
