Hellroaring Drainage
Incident details include images

Shallow snowpack ~30", west facing terrain around 8200' is faceted except for the top 6 inches. We observed poor structure and fair to good strength due to a lack of distinct layering (its mostly facets top to bottom).

On an east facing slope at 8,300' we observed a slightly deeper snowpack, but still widespread faceting. Poor structure but good strength. During a pit test at this aspect we did not get propogation on any layers (on 1/5/19.) This was all before the most recent round of snowfall however, clearly the facets present a major persistent layer that will cause issues with increased loading.

Hellroaring Drainage: Huge "Whumphs"
Incident details include images

I was in the Hellroaring Drainage Yesterday, snow depths below 7,000' hover around 18", around 8,000' snow depths increase significantly but are still shallow i.e. less than 30". Witnessed the largest "whoomphs" I have ever felt (that's saying something since last Decemeber/Jan was horrendous), interestingly much of this was felt returning on the same skin track, telling me this is a stubborn layer that may not give right away. The largest was a collapse in a meadow nearly 0.25 miles long.

After last season's two snowmobiler avalanche fatalities on Reas Peak in the Centennial Range we created this web page so riders could get good, relevant information regarding snowpack and avalanches. Although the Centennial Range is not part of the Gallatin National Forest Avalanche Center's forecast area, we are the closest avalanche center and have valuable information to share.

  • The snowpack in the Lionhead area outside West Yellowstone is typically very similar to the Centennial Range. When we issue Avalanche Warnings in Lionhead, the Centennials are also dangerous. Pictures, photos, and observations from the Lionhead area are windows into the conditions in the Centennials.
  • We designed this web page to be a one-stop-shop for anyone riding or skiing in the Centennials.
  • We need your observations to keep everyone safe. Fill out a form and let us know what you found and attach pictures or videos.
  • If you are riding in other parts of southeastern Idaho, go to avalanche.org and find the nearest avalanche center to get updated information. The snowpack and avalanche concerns in regions adjacent to avalanche centers are typically similar:
  • Another great resource for avalanche information can be found at the Adam Anderson Avalanche Project on Facebook.
  • Avalanche Education is paramount to making good decisions. All avalanche education in Idaho is listed HERE.
  • If you would like to sponsor a 1-hour avalanche awareness class for your store, club, or organization, drop us a line. We may be able to accommodate that.

Do not hesitate to reach out if you have any questions or suggestions. This webpage is a work in progress. Email us at mtavalanche@gmail.com

We hope everyone has a safe season!
