Pilot project to be considered for the Stanley slide path

By Summit Voice

SUMMIT COUNTY — A year or so after first talking up the idea of installing an automated avalanche blasting system on Berthoud Pass, the Colorado Department of Transportation is getting ready to hold a public info session to discuss the idea with the public.

At an elevation of 11,307 feet, Berthoud Pass averages about 500 inches of snow per year, and the area has 55 identified slide paths, many of them directly threatening U.S. Highway 40. The most recognized avalanche path, and proposed site of CDOT’s pilot project, is the Stanley Slide area located on US 40 at Mile Post 249.8. (more…)

Season starts for Colorado Avalanche Information Center

Daily forecasts posted online

Early season snow can quickly pile up and create avalanche risks in the Colorado mountains.

FRISCO — The Colorado Avalanche Information Center is up and running for the season, offering daily weather forecasts tailored to specific geographic mountain areas and general early season avalanche information. Zone-specific avalanche updates and warnings will start to flow as soon the snow starts piling up, at the latest by Thanksgiving, said CAIC director Ethan Greene. (more…)

Colorado’s avalanche safety program going strong at 40

Annual workshop highlights history of avalanche education, outreach and warnings, along with updates on weather and technical info

Colorado skiers and avalanche experts are revving up for the season, and the annual snow and avalanche workshop is always a big part of the preparation.

SUMMIT COUNTY — Avalanches were a serious threat in Colorado’s mountains long before people started cruising through powder on skis and snowboards. Early pioneers, miners and railroaders all faced the White Death on a regular basis way more than 100 years ago, and during the state’s mining era, entire towns were wiped out by devastating slides.

But 40 years ago, snow experts started providing formal, science-based avalanche bulletins to the public with the formation of the Colorado Avalanche Warning Center. It was the birth of the modern avalanche safety program in the state and the precursor of today’s Colorado Avalanche Information Center, which will kick off the 40th year of forecasting with an all-start lineup at the annual Colorado Snow and Avalanche Workshop.

The one-day professional development event is aimed at  snow and avalanche professionals, including ski patrollers and backcountry guides, but is also of interest to the wider backcountry community, with talks on some of the latest science and the traditional ski season weather outlook.

This year’s CSAW is October 19 at the National Mining Hall of Fame in Leadville, Colorado. In addition to the CAIC, the meeting is co-sponsored by the Friends of the CAIC and The Summit Foundation.

Pre-registration for the workshop is open online at the CAIC website. Advance registration, available through Oct. 15, is $25, but it will cost you $40 if you wait to pay on the day of the workshop at the door.

Colorado’s avalanche forecasting program is the oldest in North America, and possibly the oldest anywhere outside of Europe, said CAIC director Ethan Greene. To explore the roots of the program, the workshop will include a talk by Art Judson, considered one of the “godfathers” of avalanche forecasting in the state. Judson will describe the early days, and former CAIC forecaster Nick Logan will follow up with a talk about the more recent years of the program.

Staying with the historical theme, Ray Mumford will discuss the state’s highway avalanche safety program, and Colorado state climatologist Nolan Doesken will give a talk on 40 years of snowfall stats.

Technical talks include information on some of the latest Avalauncher ammunition, as well as new research on the effects of explosives on different types of snow.

Vail, Winter Park sued over inbounds avalanche deaths

Lawsuits allege resorts were negligent in managing terrain

SUMMIT COUNTY — Steamboat Springs-based attorney Jim Heckbert says Vail and Winter Park ski areas were negligent last winter when they failed to close or adequately sign avalanche-prone terrain within their operational boundaries — and that their negligence resulted in the death of Taft Conlin at Vail and Christopher Norris at Winter Park.

The lawsuits may hinge on very specific legal language in the Colorado Ski Safety Act, but the outcome could have larger implications for the sport, as a verdict favoring the plaintiffs could affect the way ski resorts manage internal closures, which, in turn, could affect access to public lands.

In the Winter Park lawsuit, filed in Grand County District Court, Heckbert alleges that Intrawest Winter Park Operations Corporation, through its employees,was negligent in disregarding forecasts and warnings regarding high avalanche danger existing within the boundaries of the ski area, and negligent in not closing the area or warning skiers of the danger.

By Bob Berwyn

SUMMIT COUNTY — The Colorado Avalanche Information Center has switched to a spring forecasting mode, ending zone-specific updates in favor of a statewide forecast emphasizing overall spring avalanche awareness.

The CAIC will continue to issue weather forecasts twice a day, through April 30, with statewide avalanche statements Sunday, Wednesday, and Friday, by 5 p.m. through the end of April and into May if conditions warrant.

CAIC director Ethan Greene said the change came a couple of weeks earlier than usual, prompted by a March snowpack meltdown that left many mountain areas nearly high and dry. (more…)

Dangerous avalanche conditions persist across Colorado's backcountry.

Avalanches making news in Colorado

By Summit Voice

SUMMIT COUNTY —Colorado’s snowpack turned deadly again last week, as skiers and snowboarders tested the sketchy conditions in dangerous terrain and paid the ultimate price. Several climate-related stories also made the top tier this week, with one article that examined the link between wildfires and climate and an end-of-the-week story on the ongoing battle over a European Union plan to reduce airline carbon emissions through a cap and trade system. Along with environmental coverage, a photo essay on Africa by correspondent Garrett Palm was also a reader favorite.

Colorado: Avalanche warning expanded to S. San Juans

The avalanche danger is rated as considerable to high across all of Colorado's backcountry mountains.

Vail Pass to close Monday morning for avalanche control work

By Summit Voice

SUMMIT COUNTY — Sunday’s storm brought widespread snowfall to the Colorado mountains, with the deepest accumulations in the San Juans, where Silverton Mountain and Wolf Creek both reported 14 inches of  new snow Monday morning.

Vail Pass will close at 9:30 a.m. for avalanche control work, and other high mountain passes will likely remain snowpacked, icy and slushy for much of the day, with reduced visibility in areas of blowing snow. Get the latest info at www.cotrip.org.

More snowfall totals include 8 inches at Monarch, Crested Butte and Telluride, with genealyy 2 to 5 inches across the northern mountains.

As a result of the widespread snow in the southwestern mountains, the avalanche warning has been expanded to include the south San Juan zone, and extended through Tuesday. Dangerous avalanche conditions will prevail in the region, with triggered and natural slides likely in many areas, on all aspects and elevations, according to the Colorado Avalanche Information Center. Travel in avalanche terrain is not recommended. (more…)

Colorado skiing: Test your avalanche search & rescue skills and some new gear at Arapahoe Basin’s annual Beacon Bowl

SUMMIT COUNTY —If you got a new avalanche beacon for Christmas but haven’t taken it out of the box yet, this coming weekend might be a good time to test it at the Feb. 11 Beacon Bowl at Arapahoe Basin.

The annual event is huge fundraiser for the Colorado Avalanche Information Center, and a chance to measure your beacon search skills in a competitive setting, with the adrenaline flowing — the follow up with ongoing practice sessions, because statistics show that rescue experts who practice on a regular basis are about twice as fast at finding and uncovering a buried victim than the average recreational user.

That’s critical in an avalanche rescue situation, because the odds of surviving a burial drop rapidly after the first 15 minutes, and outside help is unlikely to arrive within that that timespan after a backcountry slide.

“That 15 minutes goes by really fast,” said Dale Atkins, president of the American Avalanche Association. (more…)

Colorado: Freshies, and backcountry avy warning

Backcountry travel not recommended in avy terrain

Buffalo Mountain looks good with a fresh coat of white.

SUMMIT COUNTY — Ski resorts rejoiced in an overnight storm that dumped 11 inches at Vail, 9 inches at Copper Mountain and similar amounts at most resorts in the northern and central part of the state. Get the full snow report from Colorado Ski Country USA.

Some roads remained icy and snowpacked Friday morning, but Loveland Pass was the only reported closure, and Highway 6 should re-open once crews have controlled the avalanche hazard.

In the backcountry, an avalanche warning is in effect through 12 p.m. Saturday, Jan, 28, as forecasters warn of dangerous conditions, with both natural and triggered snow slides likely on many slopes.

The storm added anywhere from .5 to .75 inches of snow-water equivalent in a 12-hour period. Combined with strong winds and a weak base layer, all the ingredients are in place for another round of dangerous avalanches. Only the South San Juans and the Grand Mesa zones are excluded from the warning, but even in those areas, the hazard is rated as considerable.
