This area on Quandary Pk. frequently slides. A properly equipped group will all be carrying shovels and avalanche beacons turned on to transmit on open slopes where avalanches are suspect. A hand lens to inspect the snow grains and a inclinometer to measure the slope are handy. Ski poles that turn into a long probe could help determine where to dig if someone is buried. Some skiers would argue it is more time efficient to just use the beepers to pinpoint where to dig.
Several people are safer traveling together than just two.
It is foolish for everyone to take their runs at once. Preferably, one should ski at a time while the others watch from sheltered vantage points. This way, if a slide occurs and someone is buried, hopefully it will be only one person and everyone else will have seen where they ended up not to mention be on hand to search with their beacons and dig. Of course this precaution should be followed on the trip uphill as well. It is a natural tendency to bunch together but that is no way to cross avalanche terrain.
