Avy Safety: Lessons Learned

By Mitch Weber

"Ed, I can hardly hear you...the wind is howling up here...giant cracks are shooting out all around us...we'll call you when we get lower...gotta go for now..."

I slid the little Talk-About radio back into the front pocket of my parka and zipped it up. I didn't realize that I had inadvertently hit the channel change selection button and switched it to 3-20 from 2-20. A little mistake that would cause big worries for a few people later that afternoon.

The day had started off in a most excellent fashion, as most powder days do. All of the ski partners met at the base of the mountain a little before 7:00 am. We had 5 cars to drop this day, that meant four runs with up to 3,000 vert each would be possible, all without any shuttling. The gate was open, there was a terrific base, it had been snowing overnight and was still snowing lightly right now. The forecast was for it to stop, then pound again later that night. The five of us quickly decided to leave my car, Len's truck and Matt Kalin's new AWD van at the bottom. We stashed Steve's old Subaru at a place we call "the mid drop", a little pull out parking spot where, with a little climbing, we can exit back to the road after grabbing a quick 1,200. We continued up to the top in Ed's Explorer. Once there we jumped out and waxed up. You know you are in for a good day when you pull out the "green extra" and that is what we were using.

After the first run to the bottom, we were all grinning like fools. We had enjoyed fresh tracks through nearly a foot of fresh, taking an old favorite route down through "Church Camp Bowl". We were so stoked, we hardly noticed that it was snowing pretty hard now. As we were putting our skis into Matt's van for the trip back to the top, old George, a Forest Service ranger, pulled up and told us they were thinking they would close the gate soon and that we better plan on calling it a day. His heart was not in chasing us off the mountain though, and in any case he knew we wouldn't really listen anyway, he had been there before. We all nodded that we understood, then waited for him to drive down around the bend before we jumped in the van and headed up. Twenty minutes later we were back on the snow and skiing to the mid-drop. The snow was even more glorious than the last run. We couldn't believe how great this day was going, it was early, with two cars still at the bottom. And it was flaking big time now. Half dollar size flakes floating lazily down to the ground! We were all in a near dream state, pumped from the skiing and awed by the white beauty around us.

"Oh man this is bad what do you want to do" I asked Len, as we both looked down at my skis where a crack had shot out 20 feet in front and 10 feet behind. We were just off to the side of the ridge top, so we were not in any immediate danger..."I don't know, we can't go back, we don't have any other way down, let's just go slow, and when we get to Chestnut Chute we can check it out." I cinched my hood tighter around my face and continued to try to pick my way down the ridge, with Len in front.

Once again, as we loaded the skis onto the roof rack of Atwater's ancient blue Suburu, we were jolted back to reality by the appearance of another Forest Service truck. This one with James at the wheel. He is the winter recreation manager in the area, we knew our goose was cooked. There would be no bs this time. "We are closing the road and the gate, everybody else is off the mountain, we have been waiting on you guys, you have to get your cars and go down, now. I'll follow you." A collective low groan went up from the group.

As we drove to the top, Len and I were both silently thinking the same thing. Our cars were at the bottom. We could ski down! We could even go backside! (down to Pine Mountain, a little town to the north where I used to live). I whispered this to Len, riding behind me, scrunched up in the cargo area. He nodded. The bummed silence was broken by Matt who said, "what a drag, this sucks, all this snow, the cars in place and now we have to leave, we have to drive down." Len diplomatically interjected, "well, not all of us". Groan, guffaw, hurumph, "that's right you guys can ski" said Matt, in almost a whine. I asked "Ed, do you think you could pick us up if we go backside?", "yeah man, of course" he answered, you can always count on Ed, he is that kind of guy. Poor Matt could hardly contain himself "this sucks" he said again, and now it was a full-on whine. "Sorry" said Len, quietly. And we all laughed at his understated insincerity. I gave him my best cat-that-ate-the-bird grin.

"The doggers become the dogged" said Len with a nervous laugh as we stopped again to consider our options. Whenever we dropped off to the leeward side of the ridge to escape the driving wind and blowing snow, cracks would again shoot out from our skis and we would move back over to the windward, crusty side. It was nasty, no doubt about it.

We got to the top and said goodbye to our partners. Before leaving we confirmed that we would call them on the radio for a pick-up when we got close. "We'll be in the Jacuzzi so just give us a shout" said Ed, who lives in Pine Mountain, in a beautiful log home, just minutes from our expected exit point. As we kicked up the two mile trail to where we would jump off to hit the backside, Len and I tried to decide on a route. It came down to a decision between the "Slide Area" (so named because it is a giant bowl, cleared of trees from an awesome mud slide, many years previous) or Chestnut Chute, a steep, direct plunge right to the top of Chestnut street in town. Since we didn't have a rope with us, or descenders and harnesses for the rappel over the waterfall at the bottom of the slide area run, and since we liked the idea of doing a chute, we opted for Chestnut. In retrospect it is hard to know which would have been the better decision. Conditions turned out to be very weird all around.

The kick up was a pleasure, my wax was working just right and I was getting excellent kick and glide, a rarity for the fat Snow Rangers and beefy step-in bindings I was using. The snow was still falling lightly and the forest was peaceful. There was no one around for miles. Mt. Pinos was closed-down to the outside world. No snowplayers at the parking lot, no cross-country skiers on the trails, no nordic patrol at their base. We had the mountain all to ourselves.

We got up to First Meadow, one of the big, open alpine meadows on the Mt. Pinos summit ridge. As soon as we came out of the trees we were hit with a blast of wind that took us by surprise, it had been relatively calm at the parking lot and on the kick up. It was the first warning sign, but so often we drop off and it is calm. Not today.

Starting down the ridge leading off the top and to the north, the snow was powder and fun. After we had gone about a quarter of mile down towards the top of Chestnut Chute, things began to change, the snow on the leeward side was wind deposited and began to show signs of instability. We knew we had a potential problem but continued on with caution. As we moved down the ridge it began to blow harder and harder, the snow got crusty. We tried to duck out of the wind, seeking better snow and shelter from the storm. Big cracks began to appear beneath our skis and we realized that the slide potential on the leeward side was high. This realization was alarming and it was at this moment that my radio crackled to life, it was Ed checking in. By the time I got it out and answered him I was really worried and the fear in my voice was obvious as I told him about the howling wind and the cracks shooting through the snow.

I skied down to Len, waiting a dozen yards away. We had a quick conference. We had few choices. The snow-gate at the bottom would be closed and locked by now, and in any case we had no car at the top. When we said goodbye and headed out for the backside we had left ourselves with almost no options. This was not the first time we had done this. We had both been dropped at the top before over the years, and we always knew that it was an extra level of commitment, but this was the first time we had ever been faced with more than a theoretical situation of wanting, even needing to beat a hasty retreat and being car-less. Not just without a vehicle, but with the gate closed and a bigger storm moving in, we had to ski down. That was the only option it seemed to us at the time.

"Let's just go slow and when we get to the chute we can check it out", Len smiled and tried to be cool. "I suppose that is about all we can do, maybe it will be better down lower on the windward side" I said hopefully. "Probably not" Len answered and we both laughed a bit.

Twenty minutes or so later we were approaching the top of our chute, we poked around trying to make sure we got the right one and being careful not to find our way into it before we wanted to. I crossed above the entrance to a dead end couloir--more cracks. So much for better conditions on this aspect. Moving further to the right I saw Chestnut. "There it is Len, we're here". He skied over to me and we looked down the long steep gully that was our route out of here. Even though it was only afternoon, down below the first lights were twinkling on in Pine Mountain. The cabins and houses 2,000 vertical feet below us looked warm and inviting. "Lets ski around that little outcrop and enter the chute from the side, that looks like a safe spot to check it out", Len suggested and I agreed.

Once there, we found ourselves about 40 or 50 feet below the top of the chute, there were small trees above and below us, with the wide, open beginnings of the chute stretching across in front of us with a few more small trees on the other side. We briefly considered ski cutting the slope but quicky ruled that out when we realized how much unstable snow was above our position. Looking up we could see snow swirling into the chute off of a little wind lip. Len said, "I'll tell you what, I'm going to make a quick jump turn, pretty much in place and head right for that tree, the one on this side directly below us, we can see what happens, what do you think?" I answered that I thought it was a good idea, "but make sure you get right to your safe spot and stay out of the chute" . "Don't worry, I'll land the turn right below us and grab the tree." At this point I told Len to wait while I got out the camera, but then changed my mind, deciding to stay focused on this critical moment. I told him to go ahead. "OK, here I go...", Len planted his left, downhill pole, leapt up, drove his outside hand down and around, his skis snapped around in the air and landed with a thud...

Crack! The sound was like a tree limb snapping in half, a big tree limb. I saw the crack run 40 feet across the chute in a flash and I looked over to see that Len was safely out of harms way, holding onto the tree, in fact he was behind me! I shuffled back a bit and I watched, amazed, as the lower half of the slope, below the crack, seemed to drop an inch or so, like one big plate. A plate 40 feet across and at least 60 feet long. Slowly the entire slab began to move downhill. "There it goes!...holy shit", I looked up and, what seemed like two full seconds later, the upper slab seemed to drop just like the first and then it to started to slide. There was a tremendous sound as both slabs crashed down into a narrow, rock walled area below and broke up into chunks. The snow continued down out of sight but we could hear it for quite awhile.

Len turned around and side-stepped up a to my position and we both were alternately speechless, laughing, shaking, and soberly evaluating our next move, everything at once. "Well, we cleaned it out didn't we?" I said. I looked up to check for hang fire, and to see if there was much more up there waiting to rain down on us. I could see a 20 to 24 inch crown but it looked like the chute had slid right near to the top and there did not appear to be much more up there. The snow was still swirling off the wind lip, which now now looked like a snarling lip!

There was a feeling of mountain peacefulness that had returned right after the snow stopped sliding. The contrast between this and the violence of just a minute earlier was striking.

If you have never been in this situation it is hard to understand what was going though our minds. Logic told us that the chute was clean and safe, but neither of us had the least bit of desire to be the first one in. "Well bud, go ahead, it looks good now"...I had to try. "No way, it is your turn, I did my part" said Len. I had to admit that he had a point.

"OK, I'm going to ski straight over to that tree on the other side and grab its branches." I stood there for a minute or two more, screwing up my courage and then shot across as fast as I could, almost in a tuck. By the time I got to the tree, grabbing the branches seemed kind of dumb but I did it anyway. Len waited for me to get turned around and then he joined me. We picked our way down a bit in this fashion, from safe spot to safe spot, until we got past a little crux and around a bit of dog-leg where we felt safe to resume more normal skiing. We took no joy in the descent. All we wanted to do was to get out of there.

In all the hub-bub we completely forgot about the radios and spaced out calling Ed and the boys for our rendezvous. Nearing the bottom it did cross my mind that it was odd we had not heard from them, but I figured I would deal with calling when I got off the snow, which was really all I wanted to do right then.

We came around the last corner, out of the forest and onto the cul-de-sac at the end of Chestnut Street in Pine Mountain. Matt was there waiting and he wasn't too happy. "What is wrong with your radio? we have been calling you for almost two hours with no answer (I had no idea it had been that long) ....give me that thing..", I surrendered my radio and he said "what a couple of gapers, your radio isn't even on the right channel, no wonder you didn't hear us, we have been really sweating it, the last thing we heard was 'there are cracks all around' and then nothing but silence...".

All I could say was, "Matt, I'm very sorry, I can see you are pissed but we really don't have any emotion left to give at the moment, all I can say is 'I'm sorry' but I don't really have the capacity to worry about it right now...you wouldn't believe what just happened..." And we started to tell our story.

Right and Wrong; Lessons Learned:

First, let me make clear I understand that, to some of you, our little story will not seem like much. There are skiers, in the Wasatch in particular, who actively seek out avalanche prone chutes. These skiers will saw off a part of the cornice and use it as a kind of "backcountry bomb", triggering a slide to clean out the chute before they ski it. We are not that kind of backcountry skiers. Like most of you, we try to avoid going out in high risk avalanche conditions, but if you participate in this sport long enough there is a good chance that you may find yourself in a situation similar to the one outlined above. I think it is useful for us to analyze this account and see what the lessons learned might be.

Len is adamant that our first mistake was to be anywhere near Chestnut Chute on that day, and he has a good point. In our neck of the woods (southern California), the window of high avalanche danger is a narrow one. With our low latitude and maritime snowpack, the risk is high while the snow is falling, especially during wind events. As soon as it stops snowing the danger drops off pretty quickly. Wait a day and you will almost always be fine (but of course one should not assume anything and let one's guard down). We were definitely in the wrong spot at the wrong time. The unfortunate thing is that during storms is when the best snow is to be found, we routinely ski during storms, what we don't always do is ski steep, north facing chutes while it is snowing. And with limited options for retreat.

Looking back, the turn around decision point, the point we skied right past, was when we hit First Meadow. We got there and found that it was blowing hard and still snowing. We should have bagged it then, turned around and skied the east flank down to Pine Ridge, where Len and Steve both live. We could have taken the same route we did earlier that day, or even another. It would have been a long ski down and there is a good chance we would have arrived after sunset, but it would have been safe, the snow conditions were much different and the wind was calm over there. It is a route we have done dozens of times in the last 10 or 15 years, we could have easily made the last part in the twilight or even partial darkness. Once we had descended down the ridge towards the chute we were committed. Lesson learned, be aware of your go/no-go point.

As I mentioned in the story, we have left the top parking lot, after being dropped off, bound for the backside , many times. It has always been in my mind that having no car at the trailhead was not the safest situation, the level of commitment that this approach requires is pretty high. Still, usually there are other skiers and folks at the trailhead, in fact I can't remember a single time that we have dropped the backside when the snow-gate was closed at the bottom and the mountain deserted. This fact really upped the ante, and frankly, that thought never entered my mind as we shoved off. Another lesson learned.

What did we do right? I think the number one thing we had going for us was the fact that both Len and I have spent many years learning about avalanche safety. We have taken multi-day avalanche courses, have attended refreshers, and we spend time at the beginning of each season re-reading our avy materials. It has been said that the most important avalanche safety gear you can carry is between your ears, and never has this been more clear to me. We recognized what was going on and approached the area of mortal danger with extreme caution. If we had jumped right into that chute from the top, and ooh it looked good, there is a very good chance that I would not be writing these words today.

Approaching the gully entrance we stopped down, evaluated the conditions carefully and came up with a plan to enter it from a safe spot. We made the right decision to not attempt a ski cut that far below the top. We correctly identified the island of safety below us that we could jump-turn down to, and we were expecting that the chute might let go. If the slope had not slid after the first turn we would have continued to hug the side, hop turning down as safe spots became available, but we were, in fact, lucky that it let go right off.

After the slide, we were smart to ski down carefully, one at a time, from safe spot to safe spot, watching each other carefully. We only resumed normal skiing when we had gone further down and around the bend, but we still went one at a time, with the non skiing partner watching carefully both the skier and the upper part of the chute.

Oh and one other thing, I really wish that I had an mpeg of that slide to share, but perhaps had persisted in my desire to get the camera out, things might have turned out differently. Maybe I would have moved further out for a better angle. Ironically, before starting to write this story I pulled out the floppy disk I was shooting on that day to put together a little movie. There was a cool scene with Len kicking up over a rise on the way down the ridge. You could hear the wind blowing and see the snow flying. The disk froze in my computer and would not write to my hard drive...I would have lost the shot of the slide anyway.

Post Script:

We have been using radios for many years. And for what we do they are almost a necessity. Recently we switched to the little Motorolas and I am only partially satisfied with them. Our original radios were full size, single channel, 1 watt affairs that we bought from the local volunteer fire department when they upgraded. We wore them on our chests in radio packs like the ski patrollers at the resort use. They were always handy, you could even answer a call while in motion. They were fool proof and twice as powerful (the Motorolas are only a half watt). Their massive five cell rechargeable battery packs would last for days in receive mode. The small size of the new radios is both good and bad. The bad thing is they are really easy to lose (that short term memory loss thing) and we tend to put them in our packs or in a pocket, making them hard to get to. Even on a lanyard around your neck you still have to keep the unit inside a pocket to keep it from bouncing around. I miss the old radios. I'm thinking I am going to take my two, and put new battery packs in them and bring them back for situations like this. The Talk-Abouts have let me down too many times now.

Of course, I could have stayed in touch with Ed if I had used the "lock" feature that keeps accidental channel changing from happening, but it seems like it is always something with the Motorolas. They are fine for at the resort, I suppose, or for a family at a theme park, but they are not serious tools. After he heard the last message and then we then went overdue, Ed had called a couple of other ski partners and they were about to mount a search for us. Others may have been put at risk due to my oversight and that is not cool at all.

If you take nothing else from this story I hope that those of you who have not taken an avalanche course will do so. Make plans right now. Don't wait. I know too many backcountry skiers who have all the gear, beacons, shovels, probe poles, inclinometers, etc, but who have not spent a weekend learning from an avalanche professional. I had not given it much thought lately but after the above incident I can't tell you how incredibly foolish this now seems.

It is clearer to me than ever before that given a choice between having all my safety gear with me or having in my head the accumulated knowledge gleaned from experts in avalanche awareness, I would choose the latter without a moments hesitation.
