Zones of potential rock avalanche run out. Green zones estimated using empirical techniques by John Allan in 1932. Red/blue lines estimated using updated empirical models in 2000.  At this time (2000), only a single dry avalanche simulation had been carried out.  Updated simulations are currently being run with results available spring 2007.
