Anthracites Avalanche Fatality

CBACAnnouncements, News

A backcountry skier was caught, buried, and killed in an area of the Anthracite Range locally known as the Playground (east of Ohio Peak). The skier’s partners were able to locate and extricate him from the avalanche debris, but he died from injuries sustained in the avalanche.

The skier was caught in a small avalanche that broke one to two feet deep above a cliff band. He pulled his airbag and was carried over the cliff. Below the cliff a deeper and much broader avalanche released. It broke on a layer of buried surface hoar two to three feet deep. The combined flow of debris from both avalanches carried the skier through trees and completely buried him on the slope below.

Our condolences go out to the friends, family, and everyone involved in this incident.

CAIC and CBAC staff visited the accident site on February 12, 2024. A summary report is here.

Capital Campaign

CBACAnnouncements, Backcountry Notes, Events

Dear CBAC Community,

Our motto is, “We do it every day,” and for 24 years our commitment to safeguarding lives in our valley through professional weather and avalanche forecasting has been unwavering.

Since our humble beginnings in a basement on Sopris Avenue, our center has grown and evolved and set the standard for excellence as a locally run avalanche center in this critical public safety service. The success of our model has others recognizing the value of what the CBAC is doing and since we started, eight similar centers have opened throughout the West and in Alaska.

Having a forecast team that lives in the area brings unmatched expertise in understanding our local snowpack, weather patterns, and the intricacies of our terrain. It is the backbone of our safety efforts in the valley.

Yet, like so many other entities in the Gunnison Valley, we are not immune to current economic challenges and keeping experienced and qualified staff in place has become more and more difficult. We’re at a pivotal moment and we need your support.

To address that, we’ve launched a Capital Campaign aimed at establishing an endowment fund dedicated to our forecast staff. Our goal is to raise $50,000 and we’re excited to say that we’ve already received a generous offer to match the first $10,000 in donations.

Your partnership in this campaign is a direct investment in safety and expertise. Your commitment to our cause will empower us to retain and support our exceptional staff, not just this year, but for years to come, thereby safeguarding our ability to provide top-tier avalanche forecasting.

As a token of our gratitude, we have a CBAC embroidered down coat from our friends at Big Agnes for every donation of $1000 or more. In addition, everyone who participates in the Capital Campaign will be entered into a drawing to spend a day in the field with a forecaster to see exactly what they do, and how they do it.

My hope is that you see the value in what we do and join us in securing the future of avalanche forecasting in our valley. Your generosity will make a tangible impact in our ability to provide a critical public safety service and ensure that we continue to “do it every day.”

Thank you and here’s to a safe and snowy 2024!

Avalanche Terrain Map for Crested Butte

CBACAnnouncements, Backcountry Notes, Events

We’re excited to release an Avalanche Terrain Exposure Scale (ATES) map of the Crested Butte forecast area to help you with tour planning. ATES is a scale used to categorize the severity of avalanche exposure, strictly based on the landscape, regardless of snowpack conditions. The ATES scale classifies terrain into five categories based on slope angle, forest density, slope shape, terrain traps, avalanche frequency/magnitude, starting zone size and density, runout zone characteristics, interaction with avalanche paths, and route options for managing exposure.  See the draft definitions of the five-level scale (V.2) below.

For this year-long project, we partnered with OnX and Beacon Guidebooks to categorize terrain around Crested Butte as Simple (Class 1 = Green), Challenging (Class 2 = Blue), Complex (Class 3 = Black), and Extreme (Class 4 = Red). We used an automated model approach called AutoATES, and calibrated the release areas and runout models using historical data from our avalanche records and local experience to tweak model inputs such as tree density and alpha angles.  Although models are never perfect, the map should provide a useful resource for route planning and identifying what terrain is relatively more or less exposed to avalanche hazards. Remember that this map is independent of snowpack conditions; some days it is safe to travel in complex terrain, and other days it is dangerous. And you can still get into trouble in simple terrain under certain conditions. This map is available for free on our website here, or under the “Resources” tab on our website menu.  Bookmark it as another tool!  You can also use this map offline in the field using the OnX app (subscription required).
