It's winter on Black Rapids Glacier

Lee and I wrapped up a successful season on Black Rapids Glacier. We removed all summer instrumentation and beefed up the three GPS that are staying for the winter with high capacity batteries. The trip started with bad weather and new snow on the glacier, but it quickly turned into beautiful fall weather. But there is no mistaking it: winter is on the way, and a thin layer of fresh powder was coating the surface.

A view of the landslides that hit the glacier during the November 2002 Denali Fault earthquake. The coating of rocks insulates the ice from most melt. The clean ice continues to melt, however, resulting in an increasing height difference between ice and rock.
