Comments
I'll start off saying that I got extremely lucky today. I made a poor choice and was lucky enough to walk away with no injury other than my mental wellbeing and a small bruise on my shin.
The day began around 6:45am with a group of 4 of us heading up toward wolverine cirque to spend the day in the area. We are all experienced riders and have good education and understanding of snow. We summited patsy marley expecting sunnier conditions but we're met with cloudy and colder conditions than NOAA had called for in the area. With that in mind, we we're less concerned about the warming slopes on the easterly facing slopes, however visability was poor so we decided to start on the west facing side because there are more terrain features making it much easier/safer to see the snow surface. My 3 partners and I did 2 laps on the westerly facing slopes skiing Ragtime, Scratch and Sniff, and Scythe. The slopes were wind scoured but stable.
By the time we reached the bottom of the basin it was around 10:30-11am but still very little to no sun, but temperatures were slowly climbing(Complacency on a noticable red flag). I've wanted to ski off patsy into the cirque for years and today the excitement got the better of me. I decided to ride it as conditions looked excellent but I didnt take into consideration the danger of riding the east facing line(New/Old snow interface with warming temperatures on a solar aspect).
Avalanche:
I dropped from the summit of patsy marley and traveresed 50 feet until I reached the line I was aiming to ski. On the traverse, I was noticing small amounts of snow breaking at my board but nothing super concerning. I made 3 good turns, then on the 4th one. the snow broke 3-4 feet above and behind me with roughly 11 inches of depth. - Luckily most of the snow broke downslope from me. The weight of the snow pulled my edge out from under me and carried me roughly 30-40 feet downslope until I hit my toe edge on a small rock under the surface which was enough to brake my momentum and keep me from traveling into the choke of the chute. I quickly self arrested in case anything else was comnig down. I radioed to my partners to let them know I was okay and uninjured. Knowing there could be more snow coming from the skiers left just above me, I gathered myself and made a swift but careful exit down the rest of the line to safety.
This line off the summit is steep, exposed, and has alot of complex cliffbands across the entire slope. I was aiming for the least complex line on the face and was lucky to be on my toe edge when it popped. If I had aimed for my second option just to the skiers right of my line, I would've been on my heel edge and carried through a 45-50" pitch of terrain with trees and cliffs below.
I was incredibly lucky to walk away from today unscathed. Thank you to my partners and the other party in the basin who were first responders who checked in on me at the bottom.
Final Reflections:
- Red Flags - New storm snow on melt freeze crust(not bonding well), Sun/Rising Temps(East Facing Line), Wind(this particular line had very little wind affect).
- A note to other riders and myself. My excitement clouded my judgement and I made an Ignorant and wrong call, leading to a "free" lesson in the mountains. This is unlikely in most cases. Always use objective data to help you make the call on what you plan to, or not to ski.
- I have uploaded a couple of photos to show the accident. Blue lines we're my turns, red dots represent the crown and slide, yellow square is the rock that stopped my momentum.
Thanks for reading.
