Trip Planning for Northern Madison
Primary Problem: None
Bottom Line: Spring weather can be highly variable and create a mix of avalanche problems to watch out for. Snow conditions and snow stability can change drastically from day to day or hour to hour. Anticipate rapid change and plan accordingly. Plenty of snowfall over the winter with more spring snow to come makes avalanches possible into summer.Past 5 Days

From obs 5/23/24: "Toured to the top of PK during today’s storm. Snow was very wet and heavy. We saw no other slides or signs of instability on the way up. Coming down skiers right of flippers, all 3 of us caused small slides and cracking within the new snow. I triggered the largest slide, which was 6-8” deep and 12’ wide." Photo: T. Jordan

A skier triggered an avalanche on a test slope in Beehive Basin, breaking 12-16" deep and 75' across. The slide failed within the new snow.

On 5/4/24 Skiers triggered large wet loose slides on the Fin near Cooke City

A group remotely triggered a wet slab avalanche from the ridge top. There were shooting cracks that connected their location to the avalanche. This is an interesting of persistent weak layer and wet snow avalanche problems. Photo: M Harry

A rider triggered this avalanche in Taylor Fork on 3/16/24. "Avalanche broke about 400ft wide and slid for 250 ft. 4-2ft deep at the crown."

Skiers triggered this slope by dropping a section of cornice onto the slope. This avalanche broke 500' wide, and ranged in depth from 18" or 6'. Photo: P. Hess

On 2/18/24 near Buck Ridge and Muddy Creek we saw at least eight recent avalanches that occurred at various times over the last 1-3 days, natural and/or remote triggered by riders. A group in the parking lot mentioned seeing many slides actively happen in this area on Friday 2/16. Most were 2-3' deep hard slabs, ranging from 50'-500' wide. Photo: GNFAC

An avalanche we either triggered from 750-800 feet away or it broke naturally. This avalanche happened when we were riding near the larger of the two avalanches from yesterday, on the south side of Cedar Mtn. It was a wind-loaded slope, actively loading. The avalanche was ~130' wide with 100' of 4-12" deep new snow/wind slab and 30' wide broke almost 3 feet deep on weak snow near the ground. Photo: GNFAC
