Avalanche control began in the Alps as far back as 1937, but now a lot of the research in the US into the subject happens at a place called Alta. Here’s how they do their work there, but this piece is also a fascinating look at snow and how nature creates avalanches. We think of the snow on a mountain as a solid mass. In reality, it is a layer cake created by serial snowfalls, each layer distinctive and changeable. “The snow cover is never in a state of repose,” Atwater wrote. “It is continually being pushed, pulled, pressed, bent, warmed, chilled, ventilated, churned.” The topmost layer might be evaporating into the night air; at the same time, radiant heat from the ground, or from nearby trees, could be melting the lowest layer.
