Saturday evening at 7:37 pm we had a call for a skier with a possible broken leg near the entrance to the North Couloir on the Incredible Hulk. A party of 3 had hiked in from Mono Village, waded across Robinson Creek (which as expected for spring time was running fast and cold), and continued up Little Slide Canyon. About 30 minutes after crossing the creek, they hit the snowline, and put on their skis and skins and continued up the canyon.
As the terrain became steeper below the entrance to the couloir, they removed their skis and bootpacked up the couloir. On the descent, one of the skiers fell from about 3/4 height, and tumbled and slid down the couloir, and when the fall ended, he found he had multiple left leg fractures, but most notably an open tib-fib with considerable bone exposed. The accident occurred at approximately 5 pm.
One of the group activated a PLB, and they waited for a helo to collect them (it was later learned that no PLB activation was recorded). The helo did not arrive, and one of their party hiked out to Mono Village and reported the accident to the SO. The Team was activated, and 3 large field teams were sent out. The weather was cold, and as the field teams were gathering gear, it began to snow. All teams departed well after dark; it is about 3 miles in on the trail, and just past the wilderness boundary, the field teams left the trail and found the downed tree crossing.
There is a use trail on the south side of the creek that leads into Little Slide Canyon, and all field teams used this and the downed tree bridge instead of wading the creek. At base the decision had been made to send the field teams with snowshoes as few folks had skis, skins, and ski crampons. Little Slide Canyon was covered in deep snow, and is quite steep in places, and the Team's technical snowshoes were well suited to the terrain.
The field teams arrived at the subject's location at approximately 12:42 am and found him to be in tremendous pain, and his injury grievous, with considerable blood loss. He was packaged in a SKED litter, and a long series of lowerings commenced at 1:35 am.
