LL ski hill was skiing well if that is an option?

also no signs of avi from the chair that I sould see? so might be safer/quieter near LL than Jasper?


FYI: castle to jasper, you have at least 3 route, and LOTS of skiing

1) Castle, calgary, banff, jasper
2) Castle, fernie, invermere, lake louise, jasper
3) castle, fernie, Golden, Reve, north to jasper (longer, but I hear that the golden to Reve zone has a bit of touring avail?)

enjoy the trip

Kananaskis has a wicked rain crust up to 2000m. You're best bet depending on where you stay would be along the 93n from Louise to Jasper. Many skin tracks already set, if the visibility is good it will be easy to figure out where to start.

Stick to the plan- crashidy. Don’t say nothing but 93....u gain nothing but moguls, higher prices and traffic from telling people otherwise....who needs the noise?

Thx gang, yeah we have a few weeks before we depart. We may just spend the whole time hiking 1705 for that good turn! I have been following the forecast for Marmot Basin for the last several months, seems they have an abundance of windchill, wind, cold, and wind crust. Perhaps a free day of skiing there is best used elsewhere.

[pano-dude]

No new snow in Invermere area since last Saturday. Forecast looks like blue ski and early spring down low.... New bike arrives in 2 weeks.
Catamount glacier opens today for braapin shuttle laps.

Maybe but there's snow in the long range forecast for next weekend... we'll see if it holds up.

I have a weekend pass from the wife and jasper is on the maybe list... game time decision depending on weather.

Those amounts in town are likely more on the hill.

Lake louise village side has some really good touring. The lake is at 5500ft and a few areas with good shelter on both sides of the lake. That would be roughly the half way point between castle and jasper. With decent vis there is a lot of options close

It's what ski theologians refer to as the Divine Singularity.

Daryl does have a good sense of humour. Marmot is skiing well and the Tonquin and Whistlers Creek areas open tomorrow. Positive Rockies attitude and things will come together.

After Laura’s eulogy and obituary, this accident report is the hardest thing I have written. I have been putting off writing it for weeks, but it has been eating at me. I did check with our partner on the day, Kevin, before sharing it and had him review it for accuracy. We hope that by sharing this that someone can learn something that may save them from enduring the horror that we, as well as our families and friends, the search and rescue crew, the first responders and the medical staff have endured.

Kevin Hertjaas and I had been trying to coordinate schedules for a few months to ski together. We finally made plans to meet at the Fenlands Recreation Centre in Banff on Friday January 10th at 8:30am to carpool. My wife, Laura Kosakoski joined us too.

Kevin is a well-known and internationally respected ski guide with accreditation with the Association of Canadian Mountain Guides and the Canadian Avalanche Association. Laura and I both have operation level avalanche certification and training and both logged over 80-days of backcountry skiing in each of the past 3-years, with extensive experience before that as well as a lot of summer mountaineering. I am also a member of the Avalanche Canada Foundation Board of Directors. We were all very experienced and well trained. Despite Kevin being a guide, this was not a guided day out, this was a recreational ski day for all of us.

There was new snow that week, but temperatures were forecasted to be cold, around -15 Celsius and the avalanche conditions were considerable in the alpine and at treeline and moderate below treeline. There was a deep persistent layer in the snow that was reacting unpredictably that we all knew about.

We wanted a more casual day of powder skiing, with Kevin needing to get home early, so our options for where to ski were limited. After a good discussion, we agreed to go and check out the Hector South area in Banff National Park along the 93 North. It is an area that has increased in popularity this past year, but one that none of us had been to yet.

After locating the likely access point in the trees from the highway, we pulled over and sorted our gear. We had two inReach Minis with us, as well as a siltarp, a small emergency bivvy bag and full avalanche and cold weather gear. With the equipment sorted, we began climbing the ridge through the trees around 9:30am. We all commented on the surprising ease of access and quick travel up the trees. It was also warmer than anticipated, so we stopped to de-layer.

When we finally reached treeline, we opted to start by climbing a west facing slope. As we climbed above treeline, we noted that there was a solid windslab that had a drum-like feel and opted to transition before committing to bigger terrain above us. The wind had also picked up at this point and we put on warmer clothes.

We noted a small slide path to skiers right of where we were. We identified that there was a risk we would trigger a small wind pocket as we entered it. Kevin went first and, as we suspected, he triggered a small pocket of snow that he was able to ski away from easily. I followed a line more to the right of where he was, trying to avoid thin spots that were a concern. I skied without issue and then Laura joined us. We regrouped in a small cluster of trees and decided to go and look at a south aspect instead.

We climbed up through the trees to the ridge, happy that there was no obvious overhead risk. Once on the ridge, we traversed up to the high point. The wind was starting to pick up and the visibility was limited. We transitioned from there and skied back along the ridge to a bowl/chute a little farther down to skiers left of where we were. Kevin and Laura skied first and enjoyed great snow. I entered farther left of them and also had great powder skiing. We had no signs of any instabilities in the snow on that run. We did observe big wind lips and wind loaded areas on skiers left of the lines.

Since there was a track in already, we decided to do one more lap before heading out. When we ascended back to the ridge, we noted that the wind had really picked up and it was cold. We were happy to call it a day.

We stood at the top of the run, to skiers right of the chute we had just skied and identified a possible creek hazard below us. We also tried to spot a nice access across the creek to exit onto the lower slopes. There was a cluster of trees at the bottom to the right of the path that we said we’d regroup at.

At around 11:30am we gave Laura the honours of skiing first. She skied skiers right of the line and then enjoyed great powder turns down the 400 meter or so line. When she was about two-thirds of the way down, Kevin dropped in a few meters left of her line and started skiing. Wanting to keep my eyes on them, and wanting to watch Kevin ski for pointers, I moved forward onto the ridge crest. I was a further few meters left of Kevin’s entrance and as I moved forward onto a possible entry point, the slope below me gave away. I fell off the slab I was standing on that was starting to move at my feet. I secured myself, yelled avalanche as loud as I could and watched the avalanche pick up speed and move the whole length of the slope. I followed it, trying to see if I could spot Kevin and Laura until I saw a big powder cloud shoot through a small bench at the bottom into the creek. I was shocked at the size of the slide.

As Parks Canada Visitor Safety noted in an accident report posted on December 12, 2020, it was a “slab avalanche 80m wide[…] The crown tapered dramatically along the crest of the ridge from nearly 2m in heavily wind-loaded drifts to as little as 40cm. The avalanche ran approximately 550m. [It] ran on a weak layer of facets and depth hoar near the base of the snowpack. The avalanche caused most of the snow to be removed along its path, exposing the ground and scrubby trees in many places”. They rated it as a size 2.5 avalanche.

Once the powder cloud settled, I moved as far right as I could, to the other side of a small ridge, so that I wouldn’t trigger anything else on top of Kevin and Laura below me. I skied very cautiously down the line. I could see Kevin below me, so I skied towards him. When I was approximately 50 meters above him, he told me that he saw Laura shuffling out of the way of the path into the trees and that prompted him to do the same which saved him from being caught in the slide. He told me to start yelling her name. We both yelled “Laura” approximately 3-times without a response. Kevin then instructed me to put my beacon into search mode and to get out my shovel and probe. Being below me, he initiated the beacon search and was quickly drawn into the gully. The steep angle of the slope and the debris made doing the search complicated. As Kevin yelled out the reading on the beacon, the best reading we got was 3.8 meters. We both knew instinctively that the situation was very serious.

Due to the depth and angle of the slope, we began digging at that reading. We had to clear some snow before we could start probing. After removing over a metre of snow, Kevin probed and I deployed the SOS on my inReach at 11:45am. When he finally got a probe strike, we started moving snow as quickly as we could.

With the angle of the the slope, we had to start tunnelling from almost 10 meters back of where the probe was to avoid more snow falling into the trench that we were digging.

As the time ticked away, I was trying incredibly hard not to panic and Kevin was doing everything he could to give me tasks to keep me focused. It took us almost 45 minutes, or more, to get to Laura. We were pulling out small broken branches, as well as very large and heavy slabs of snow, which slowed our digging.

When we finally got to Laura’s head, there was no obvious sign of trauma, but she was very blue and non-responsive. Kevin checked her airway, but there was no breath, although he told me there was one to keep me on track. Due to the position of her body, we could not perform CPR, so we had to keep digging to remove her from the hole.

Kevin left briefly to correspond with the Parks team via his inReach to state how serious the situation was. I continued to try and dig Laura out. Kevin soon joined me and after a further 45 or so minutes of difficult digging we were finally able to free her. We cut off her pack and hauled her out of our deep tunnel. Due to the steepness and depth, I would sit up slope of her and drag her up my body and across my chest as Kevin hoisted her legs from below. We had to do this about 5-times before she was clear of the entrance.

There were no obvious signs of serious trauma on her head or body, but there was a deep laceration on her thigh likely from a ski. I removed all the warm clothing I had in my pack and the bivvy bag. Kevin started five rounds of CPR without any response. We opted to cease CPR and put her in the bag with all our warm clothes to try and keep her as warm as we could.

We then prepared a possible landing area and waited for the Parks team to arrive by long-line. I was trying not to panic and Kevin kept making up tasks for me to do. When the team finally arrived, around 1:30pm, they packaged Laura out and then flew Kevin and me out by long-line and I collapsed into a screaming crying mess.

We later found out that Laura’s core temperature had dropped to 24 Celsius and that she had no heartbeat. She was flown to Foothills Medical Centre on Calgary where they slowly began trying to warm her core temperature and revive her. We do not know how long she was like that. They were able to revive a faint heartbeat, but she never regained consciousness. After receiving very professional care, she succumbed to internal injuries and was declared dead just after 6:0ppm on January 11th.

Assessment of the day:
We were well trained, well equipped and despite it being our first day out together as a group, we had communicated well about our objectives, what we wanted from the day and our observations. Despite that, we made mistakes that had fatal consequences.

Mistakes we made:
We knew that the forecast was for considerable danger, but we were likely too complacent with that forecast and were not cautious enough. We often ski in that rating, or higher, but we let our guard down. We knew that any avalanche would likely trigger on a deep layer with serious consequence and that the layer was unpredictable.

There were also signs that we should have paid closer attention to. We had earlier reactivity on a different aspect, there was obvious wind loading along the ridge and we underestimated the terrain’s potential. Given the avalanche bulletin for the day and our earlier observations, we should have skied safe zone to safe zone and not skied until the person was clearly in a safe area.

I likely moved forward onto a wind-loaded convex roll that triggered the slide. I should have approached the line further right where there was less loading. I know this, but because I wasn’t getting ready to ski into the line, I didn’t think about it properly.

Based on where Kevin remembers last seeing Laura, it appears as though she was standing on the edge of the safe zone, but was not well placed in it. I speculate that she was taking a photo because we never recovered her phone, so she may have not been as well protected as she could have been to take the pictures. She was either knocked by the wind, debris, or part of the slide and pushed into the gulley below her, which compounded the effects of her burial. It is also possible that the part of the trees that she was by were taken out because of the branches and deadfall we were digging out around her.

Laura was not wearing a helmet that day, which was unusual for her. I do not know if this had any impact on her survival, but given that there were trees around, as well as the density of the blocks around her, it might help in a different situation or scenario. There isn’t a good reason not to wear one.

Performing a beacon search in complex terrain is difficult. Digging and moving that much snow is incredibly hard. Despite having done deep burial practices, being fit and motivated, it took a very long time to move that much snow. The tunnelling required to get to her was much more complex and difficult than I was ready for. It would be even more difficult if there was only one partner skiing. A factor to consider.

This was a worse-case scenario, on top of a worse case scenario. Even if statistically low, the worst can happen. It is a reminder that the mountains don’t care about your level of training, preparation, or how casual your days are. They are dangerous and demand full attention and respect and discretion is always warranted.

[glademaster]

That was a tough read. Terrible for everyone involved.

[John_B]

I've got nothing to add beyond what Glademaster said. I can't imagine going through that with a loved one buried.

[El Kanone]

Yeah, that’s a tough one. Not much else to say. You know the risks and you choose to take them. Sorry for them.

[alive]

So crazy reading that earlier today. A friend of mine lost a friend there and feel for Laura and her family.

Thanks for posting that sobering report. A lot to digest and some difficult questions to ponder.
