Recent Carleton Geology alumni Bretwood Higman ’99 and Noah Finnegan ’99 were featured in The New York Times for their critical work on landslide-generated tsunamis in Alaska. As climate change causes glaciers to retreat and permafrost to thaw, mountain slopes are becoming increasingly unstable. Higman, part of an international research team, investigated a massive 2025 landslide in Tracy Arm fjord that sent a 1,500-foot wave up a mountain wall—the second-largest tsunami runup ever recorded.
