Ice on Cascade Lake
February 19, 2004
Studying ice in the field requires sampling, which at times can be a challenge. Here Brent Moore from Poplar, Montana carries a large block of ice that was taken from Cascade Lake, New York using a chain saw and ice chipper. Part of the History of Winter (HOW) 2004 Workshop, Brent and 20 other NASA Explorer School teachers will next make thin sections of the ice. Observations of the ice crystals and air bubble patterns in these thin sections can then be correlated to the freezing process and weather conditions in the vicinity of the lake.
