A summer avalanche in California鈥檚 Sierra Nevada killed one hiker and left two others injured last week, search and rescue personnel said on Friday.
, Inyo County Search and Rescue said law enforcement received word of three hikers caught in a wet avalanche while descending Split Mountain near Big Pine at about 4:30 p.m. on Friday, June 2. While two of the hikers had escaped with 鈥渕inor to moderate injuries,鈥 the third had died in the slide.
After determining that conditions were safe enough to attempt a rescue, four members of the team flew in a naval helicopter to Red Lake, about 2,000 vertical feet below the site of the avalanche, and climbed to the scene of the incident. After helping evacuate the two surviving hikers by air, the team camped out at Red Lake, planning to return the next morning to recover the third hiker鈥檚 body.
Retrieving the deceased hiker, however, turned out to be tricky for search and rescue personnel. The next morning, one member of the team flew to the accident site in a California Highway Patrol helicopter, but rough weather conditions prevented them from successfully recovering the body. Instead, the entire team climbed back to the site and lowered the hiker鈥檚 body by litter to near Red Lake, where the helicopter waited.
Though not as common as their winter counterparts, fatal summer avalanches aren鈥檛 unknown, especially after heavy snow years such as the one the Sierra just notched. Warming snow can cause loose, wet avalanches, where unconsolidated slush begins to slide at the surface. Those avalanches may not often bury hikers, but they can still be deadly: , the Eastern Sierra Avalanche Center noted that last week鈥檚 avalanche apparently swept all three hikers in the party over 鈥渟teep and rocky terrain.鈥
Inyo County SAR noted that last week鈥檚 emergency response was the third fatal accident in three weeks where snow was a major contributing factor. The incident on Split Peak follows a skier鈥檚 death in a slide on Mt. Hurd on June 14 and a climber鈥檚 death on the north face of University Peak on June 30.
