The skier, identified as Las Vegas resident Punan Zhou, was swept about 500 feet (152 meters) down Mummy Mountain before friends found him using a location-tracking device, said Sgt. Matt Marlow of the Las Vegas Metropolitan Police Department's search and rescue team.
Authorities on Monday initially described the man as an injured hiker.
Mammoth Mountain has surpassed last year's season snowfall total and, with 419″ of fresh snow at the summit, is now officially the snowiest ski area on Earth. 310 inches have dropped at the Main Lodge, including 13 feet since January 1. The resort also has the deepest base in the country.
Mammoth has been closed today due to the intense snowfall conditions and very dangerous travel in the area. Roads have been heavily impacted and are not plowed. The resort will focus on avalanche mitigation work today and protecting our equipment. They plan to reopen tomorrow, January 11.

In Kazakhstan, highways are blocked. In Tajikistan, schools have been shuttered. Officials in Kyrgyzstan are pleading with apartment-dwellers to close windows to basements to avoid water pipes freezing. Trees and electricity pylons in Uzbekistan are crashing to the ground under the weight of snow.
Whole swathes of Turkmenistan, typically the warmest country in the region, are blanketed in white.
The movement on highways in Kazakhstan is so bad that Uzbek officials have even warned their own motorists against going there until the weather eases.

One snowmobiler died and another was missing Saturday after becoming buried in an avalanche in unincorporated Grand County, Colorado, officials said.
The pair were riding snowmobiles when a wave of snow hit them on the east face of Mount Epworth in Grand County, about 6 miles east of Winter Park, according to the Colorado Avalanche Information Center.
The avalanche was reported about 2:15 p.m., and responding sheriff's deputies, search-and-rescue crews, ski patrol members, and local good Samaritans found the 58-year-old from northern Colorado buried in snow, the Grand County Sheriff's Office said.
They couldn't revive him, and he was pronounced dead at the scene, the office said in a statement. The man's identity was expected to be released later by the county coroner, it said.

In some areas the snow banks in the middle of the road are five feet high. Normally, these banks are not much higher than one-foot.
About two feet of snow fell in Rawlins between Sunday night and Wednesday morning, and the snow drifts were several feet deep. Even people with four-wheel drive were getting stuck in roadways.
Michael O'Brien, the utilities supervisor for the City of Rawlins, and his crew helped remove much of the snow. He said typically the area gets only a couple inches of snow in a storm.
"With this amount of snow though, it was very difficult," he said. "I mean, we had everybody from all different departments, different vehicles, every department had a vehicle out there, backhoe skid steer somewhat, trying to remove snow in places."
It has been snowing heavily in some of the Norwegian ski resorts over the past few days.
Those out in the snow at the moment have some of the best conditions in Europe.

California's snowpack was measured at 174 percent of the historical average for the year Tuesday, boosted by recent storms that drenched the state during the holidays and brought snow to the mountains.
The state could see even more rain and snow this week and into the weekend, bringing much-needed water supplies.
"While we see a terrific snowpack—and that in and of itself may be an opportunity to breathe a sigh of relief—we are by no means out of the woods when it comes to drought," said Karla Nemeth, director of the California Department of Water Resources.
