Since the early 1970s the changes of Black Rapids Glacier have been measured annually. Initially this was done by the USGS, then UAF. Sometimes, we have funding from NSF to continue these measurements. But often we don't and in those years we've relied on volunteer pilots to get us there for a day to do the necessary measurements. This year I got my own wheel-skis, and for the first time I was part of the volunteer flying team, the Black Rapids Air Force! We couldn't have chosen a more beautiful day!
