Looks like a skier was killed by an avalanche skiing in-bounds at Snowbird in Utah.
It took one of the most "experienced" crews in the country an hour to find her. With 7 avalanche dogs! Seems like somebody, actually many people, messed up big.
This probably wasn't a massive debris field, just a small slide in steep terrain. It either took 59 minutes for the first dog to arrive or the area was totally contaminated by other people. Avalanche dogs are amazing.
