Ski guides in spotlight as investigators probe deadly California avalanche

An investigation to determine if backcountry guides were criminally negligent during a California ski trip that ended with eight people killed in an avalanche and another presumed dead has surprised legal experts, who said the probe has scant precedent.

Backcountry tour clients typically sign waivers of liability that shield guides and their companies from potential lawsuits. And skiing is recognized by courts in California as inherently dangerous, attorney Andrew McDevitt said.

That means recreational skiers assume certain risks, such as potential collisions with rocks or trees and changing snow conditions.

McDevitt and other attorneys in California, Colorado and Utah who handle civil cases resulting from skiing accidents said they had not previously heard of a fatal avalanche during a guided trip that sparked a criminal investigation.

But this week's avalanche is drawing a closer look likely because of its scale and the decision to proceed despite forecasts indicating potential avalanches, McDevitt said. The slide was the deadliest in the U.S. since 1981, when 11 climbers were killed on Mount Rainier in Washington state.

Utah ski injury attorney Rob Miner points out that the waivers signed by backcountry tour clients don't absolve the guide companies of responsibility if they don't follow appropriate safety protocols or fail to fully inform their clients of the risks they face.

''They're guides. It is presumed they will not guide you into an experience that may kill you, or that creates an unreasonable risk of death,'' Miner said.

Pivotal moments for investigators may include the guides' choice to embark on the three-day backcountry trip with 11 clients at a time of heightened avalanche risk, followed by the decision to ski out Tuesday after avalanche conditions had worsened due to a severe storm.

The Nevada County Sheriff's Office declined to share more information when it announced the investigation Friday. A state agency that regulates workplace safety also said it opened an investigation into the tragedy.

The guides' decisions — and how they were communicated with their clients — also could shape the outcome of any lawsuits filed over the deaths, attorneys said. It's not yet known what access the guides had to the latest weather reports when the group started to ski out.

''There's a lot of speculation,'' said attorney Ravn Whitington, who specializes in ski injury and wrongful death cases in Truckee, California, near where the avalanche happened. ''What investigators know at Nevada County Search and Rescue, the Nevada County Sheriff's Office and the Nevada County District Attorney's Office are just not known to the public.''

Blackbird Mountain Guides said in a statement that the four guides were certified in backcountry skiing and were avalanche education instructors. The company said its guides stay in touch with senior employees at Blackbird's base during trips to go over conditions and potential routes.

The 15 skiers began their trip Sunday, just as warnings about the storm were intensifying. By early Tuesday, officials cautioned that avalanches were expected. Safety experts say it is not uncommon for backcountry skiers to go out when there is an avalanche watch or even a more serious avalanche warning.
