Accident and Rescue Summary
November 25, 1989, Mark Miller Avalanche Fatality, Tony Grove South
In mid-May 1990, the body of 24-year-old Mark Miller, an expert skier from River Heights in Cache Valley who had been missing since November 25, 1989, was found by two backcountry skiers about a third of a mile south of Tony Grove Lake. Although inconclusive, the evidence indicates that an avalanche killed him. This was the first avalanche fatality in Utah in nearly three years.
An accomplished skier, Mark Miller frequented the Logan area backcountry and was known to ski extreme terrain like the cliffs on the backside of Beaver Mountain. The previous year, he’d skied in the Tony Grove area at least a dozen times. Mark was a very experienced and fearless skier, but he had never taken an avalanche class, did not carry avalanche rescue gear, and was alone.
With about a foot of new snow and continuing snowfall, November 25 was probably the season’s first opportunity for good powder conditions. Friends last saw Miller hiking alone on with alpine skiing equipment. He walked on foot, following the tracks of some snowboarders leading up the ridge from Tony Grove Lake, where he parked his car. The last person to see Mark, a friend and associate, said he mentioned heading toward the Mount Naomi area to go skiing.
A foot of snow had fallen the day before. Much of the new snow fell on bare ground, but some fell on a thin layer of recrystallized snow still remaining on the more northerly facing slopes—snow left over from the first significant snow of the season in late October, nearly a month before. There was a break in the weather, with an incoming cold front promising prefrontal winds and snowfall to commence in the late afternoon.
Miller did not return that evening. Two friends drove up to Tony Grove Lake that night around midnight, found his car there, and searched for him with headlamps, following his tracks up a ridge south of Tony Grove Lake. But a large winter storm was arriving in the Logan area mountains—one of the largest of the season. They lost his tracks as they ascended the ridge due to new snow and increasing winds.
The following morning, a small hasty party on snowshoes searched through the blizzard with hazardous avalanche conditions, but they still found nothing. Two days after the accident, larger search parties searched the area and continued for over a week, with nearly 100 searchers at one point. One searcher with trained rescue dogs said that the dogs seemed to indicate near the slope where he was eventually found, but the owners wisely called them back as it was a hazardous avalanche path loading up rapidly during the storm. Another rescuer, Kevin Kobe, recalls seeing the remains of an avalanche buried by new snow on the same slope where Miller’s body was later found. The search was finally called off a week later, and smaller parties continued for another two weeks.
Then, in the spring on May 22, 1990, two Logan area skiers were out with their pet dogs when the dogs began sniffing around the area. The skiers, suspecting that the dogs had found the missing Mark Miller, began digging and found his ski poles, then just uphill of that, the body, buried under five-and-a-half feet of snow . They went to notify the sheriff.
The Sheriff’s team found the body laying on its right side, facing uphill, right arm outstretched pointing uphill, the elbow cocked straight up in the air almost behind his head, and legs out straight. He still whore a hat and sunglasses. They did not find his skis, but Tremper and Kobe went in the following day and found them less than two feet away from his boots, both skis laying parallel across the hill and the heel ejected from the uphill ski.
Because all his equipment remained so close to him and he still wore a hat and sunglasses, it first seemed to Tremper unlikely that it was an avalanche accident. Typically, an avalanche spreads equipment out over the slope and quickly tears off hats, glasses and gloves. However, the medical examiner found no broken bones, no bumps on the head, etc, which might indicate that he fell and was injured while skiing the rocky, shallow snowpack. They concluded that he “died of suffocation from being submerged in the snow.”
In his report, Bruce Tremper wrote, “So perhaps the best conclusion is that he was pushed over in place by a fairly small avalanche and died of asphyxiation. He obviously did not ride the slide very far as it would have spread his equipment out more.” Bruce believes that he must have been near where he was found when he triggered a small slide that came down from above, knocked him down, and buried him. After that, the storm laid down a few feet of new snow, which kept rescuers from finding him until spring. Tremper’s report concludes that “this is most likely an avalanche fatality but not unquestionably so.”
Tremper asks how this accident could have been avoided.
First, if he had more avalanche knowledge (he had taken no classes).
Second, if he was skiing with a partner and both had beacons and shovels and skied it one at a time, he would most likely be alive.
Bruce wrote, “It must have seemed like an innocent slope at the time. Yes, it was steep, but it had very little snow on it. Many people get sucked in by the ‘there’s not enough snow to slide’ trap. It was early season with the first skiable snow of the season and passions run high when ski fever sets in.”
The tragedy of this accident resembles most others in that it was easily avoidable.
