Maintenance crew awarded Silver Barrel for saving Cottonwood Canyon homes

Crews from the Cottonwood Maintenance Shed 2433 and members from the South Valley Maintenance Shed 2427 are being awarded a Silver Barrel for going above and beyond the call of duty to save homes and and roadways after a landslide in Little Cottonwood Canyon in May.

After finding out that an embankment was starting to slide toward homes near Alta, the crew surveyed the problem and came back quickly to address it. Working in driving rain and extreme weather conditions, the crew took three days to remove mud, rock and debris  to keep it from sliding into homes and onto the road. The crew also spoke with concerned homeowners and caretakers about what they were doing to save the homes, and helped everyone feel comfortable, even during the trying circumstances.

“[The crew] worked hard in extreme conditions, and they never complained once,” said Jake Brown, the Cottonwood Station supervisor. “They really made it happen with a good attitude even with longer shifts.”

Ultimately, they were able to stabilize the hill and install a barrier so no further damage would occur.

“The crew made a quick response and resolution to a possibly serious situation. UDOT was very approachable and willing to communicate with all parties involved,” said Frank Perkins of Canyon Services, a property management company in Alta. “It’s a real treat to have the open communication with UDOT in dealing with problems in Little Cottonwood Canyon.”

Executive Director Carlos Braceras was present to give the Silver Barrels to crew members.

“These men are the face of UDOT for the public. No one knows what I do, or what your region director does. But they know what you do. And you carry a fine balance between keeping the canyon clean and safe while also maintaining the area’s other major roadways.” Braceras said.

The Silver Barrel Award started in 2012 by then-Executive Director John Njord. It is meant to recognize those who go above and beyond the call of duty to give exemplary service to the citizens and infrastructure of Utah. Much like college football players, who receive stickers to put on their helmets for a job well done on the field, UDOT employees who receive this award get Silver Barrel sticker for their hard hats, a pin, and a certificate.

  • Jake Brown, Cottonwood Station Supervisor
  • Shawn Wright, Cottonwood Station
  • Keith Trott, Cottonwood Station
  • Michael Johnson, Cottonwood Station
  • Semi Tuiatua, Cottonwood Station
  • Tyler Connor, Cottonwood Station

Avalanche Press Conference

Last Friday, we held a press conference inviting the media to help increase awareness of avalanche safety and the resources available to those who access avalanche country, including the backcountry in Little Cottonwood Canyon.

Backcountry skiers and snowboarders endanger hundreds of people by not utilizing available information sources and entering avalanche country at the wrong time. Skiers and riders need to be aware that their actions and decisions may not affect only themselves, but also drivers along the canyon road. Little Cottonwood Canyon is one of the highest-risk roads for avalanches in North America and backcountry skiers and snowboarders need to be aware that UDOT may carry out artillery or explosives avalanche control work at any time during the avalanche season (November to May).

Liam Fitzgerald, UDOT’s Highway Avalanche Safety Supervisor, helped inform the public at the press conference of the numerous resources UDOT and our partners provide to inform backcountry users of where and when avalanche work will be carried out, including:

The press conference was a success and you can watch one of the resulting stories below.

Our next steps to increase awareness of UDOT’s avalanche resources are a social media campaign targeted to appropriate audiences. By utilizing local public opinion leaders such as professional athletes and prominent ski/boarding brands, an informative UDOT Avalanche Awareness video will be spread locally to help keep backcountry users safe.

Here’s to a safe 2013 winter season!


Alta, Utah, located on SR 210 in Little Cottonwood Canyon, is the birthplace of avalanche forecasting and avalanche control in North America.

The current Highway Avalanche Safety Program at UDOT has evolved over seventy years to its current state of practice.

The historic connection between Alta, SR 210 and avalanche forecasting seems fitting since the road has one of the highest Avalanche Hazard Index ratings in North America. Snowfall abundance, terrain steepness and traffic volume have combined to give the road a high avalanche rating of 766.

The current Highway Avalanche Safety Program at UDOT has evolved over seventy years to its current state of practice. In 1939, the United States Forest Service hired the first Snow Rangers and established the first program in North America devoted to the study of avalanches at Alta. Following WW II, The USFS hired Monty Atwater, now known as the Grandfather of Avalanche Forecasting, as the Snow Ranger at Alta.

During his years at Alta, Atwater conducted research on snow safety and became known as a world authority on avalanche control. He pioneered the use of military weapons which are still used by UDOT for avalanche control.

“It’s the work of all our predecessors that laid the groundwork for what we do today,” according to Liam Fitzgerald who as the Avalanche Forecaster for UDOT knows science of avalanche forecasting and avalanche safety programs. Fitzgerald administers the Avalanche Safety Program at UDOT which is based on three primary areas of focus: avalanche forecasting, control and rescue.

UDOT is making efforts to move away from the use of military artillery for avalanche control. New Gaz-X exploder systems have been installed at known avalanches sites.

UDOT’s Highway Avalanche Forecasts are issued for 12 hour periods for each canyon. Forecasts are based on snow-pack structure, local weather data and accurate weather forecasts. If the forecast suggests an avalanche is likely to occur, forecasters test the snow-pack for stability. Often, the tests are carried out using military artillery. Terrain features, snow-pack structure, weather conditions, and avalanche activity from the past determine targets for military artillery.

UDOT is making efforts to move away from the use of military artillery for avalanche control. New Gaz-X exploder systems have been installed at known avalanches sites. Two of the new avalanche control systems have recently been installed in a known avalanche path called Valerie’s Slide in Little Cottonwood Canyon on the lower face of Mount Superior.

The visible part of the system is a downward-facing twelve foot long, two foot diameter tube. An underground oxygen and propane storage farm feeds the gases to exploders where the gases are mixed in preparation for firing. The units are then triggered by remote control producing a shock wave that moves through the tube.

The resulting controlled slide prevents a bigger, potentially more destructive slide. The system is a better alternative than howitzer-fired or hand dropped shells since the slide area is adjacent to Snowbird Village and SR-210. Two similar units have been in operation for two years. The new units are planned to be operable for this coming snow season. UDOT has plans to install more units next year.

Although most of the time avalanche forecasting and control efforts allow for safe travel on the canyon roads, naturally occurring avalanches occasionally reach the canyon roads while they are open. When a snow avalanche occurs, and a rescue operation is needed, UDOT forecasters assume the role of Accident Site Commander in Highway Avalanche Rescue efforts along the Wasatch Front. UDOT Avalanche Forecasters are a part of the Wasatch Backcountry Rescue organization.
