Full Trip Report: https://engineeredforadventure.com/hyalite-peak-fat-maid/


As part of my short trip out to Bozeman, Logan and I had been throwing around a few ideas for the 3 days I would be there. The day before we had skied the SE Couloir on Emigrant Peak, so we were looking to expand our explorations into a different zone. Logan had been dreaming up a full Hyalite ski traverse after reading a trip report from 2013, linking up some of the prime ski lines that Hyalite has to offer.

Logan's full vision was:

Hyalite Peak

North Evil Twin (on Divide Peak)

Fat Maid

The Pinner

Second Evil Twin

Bunny Ears (on Elephant Peak)

It would be a big day, not necessarily 'vert-wise' but mileage wise. The total stats for the day would be just over 17 miles and 8,000' of climbing. The approach to Hyalite alone was going to be 6 miles, just to get to the first ski line. We agreed that we were up for the test, and talked through the terrain for the day. Most notably, there was one specific bail point that made sense for the day: out the Maid of the Mist drainage after skiing the Fat Maid. The drainage exiting from the Pinner has an icefall that we would not have been able to descend down. We needed to make our call on moving on after the Fat Maid, or we were committed to finishing out the traverse.

Trip Report

We agreed on an early start for the day, setting alarms for 5 AM and hopping in the car at 5:40 AM. Thankfully, the drive to the end of Hyalite Canyon was amazingly fast, and we were skinning by 6:30 AM. We had headlamps on for the first 30 minutes or so of the approach, but quickly the light began to stream through the trees. The approach up Hyalite Creek was mentally exhausting; extremely low angle, with confusing switchbacks. It reminded me of climbing up Mountaineer Creek towards Colchuck Lake, the torture of exploring ski lines tucked far into deep valleys.

Head down...skinning for miles. Once we popped out of the trees we could see Hyalite Peak just as the sun began to poke out behind its shoulder. We were the only ones out there...alone amongst the popular canyon. It was an awesome feeling having this area to ourselves, no other people to change the ambience.

Looking out at Hyalite Peak. We took a quick break at the base of Hyalite and noted our first line of the day, the north face of Hyalite Peak. It wasn't anything extraordinary, but there was a small gully that looked like a fun feature. We agreed to boot up to the summit and then ski back down. Our traverse would then take us up along the saddle towards Divide Peak, where the North Evil Twin lives. The hike up to Hyalite was bone dry along the ridgeline, a classic Montana feeling of boom-and-bust snow.

Logan Ridgewalker...not quite Luke Skywalker. We hiked back down a bit to the start of our ski line, where we clicked in and skied hardpack down to the bottom of the bowl where we had been just minutes ago. Not great snow, but at least skiable!

Logan Skywalker skis down the choke on Hyalite Peak. We spotted another skier blitzing their way up to Hyalite...they were really moving! We headed up to Divide Peak along the ridgeline, as opposed to booting up the South Evil Twin. We weren't convinced that the North Evil Twin was "in", so we were going to bypass it by hiking around the climber's left-hand shoulder and then dropping into the bowl. We found a break in the cornice and clicked in to our skis...but not before spotting the North Evil Twin. It was NOT in...phew, we were glad that we didn't try and go ski it.

Ski descents marked in purple. The vertical line off of the unnamed point is the North Evil Twin, which we did not ski. We opted to traverse along the ridge and drop in lower down.

The North Evil Twin Couloir...with a mighty evil rock and cliff at the bottom. We skied windboard down into Divide Basin, where we'd have a flat traverse over to Maid of the Mist. This would be a longer section of no real skiing...sad. We traversed over to a flat spot, where we basked in the sun for a few minutes. It really felt like spring...we forgot it was JANUARY!

Logan skinning across Divide Basin. Getting across to the top of the Fat Maid was both tricky and slow moving. We needed to ascend to Divide Peak, then take the ridgeline across to an unnamed point where the Fat Maid drops from. The ridgeline was corniced on the east side, and the west side was windswept and lacking snow. We pondered a few different options: Dropping north from Divide Peak and then climbing back up to the point. We decided that this option was not feasible due to overhanging cornices.Continue along the ridgeline all the way from Divide Peak to the unnamed point. We agreed this was feasible but the ridge looked slow moving and tedious.Ski west into the Storm Castle Creek drainage and skin up the southern aspect of the unnamed point. We chose this option.

The main reason we opted not to continue along the ridgeline was more because of tedium than safety. The ridge would have gone...we were just tired of postholing without skis on. The skin up to the top of the Fat Maid was SLOW. The southern aspect was getting cooked by the sun, and there was a clear change in the texture of the snow with all the radiation. The snow was sliding on the firm crust beneath in certain spots, which gave us a moment of concern. We opted to continue moving up on the aspect we were on, as we weren't overly concerned with large slides, more-so tedious slipping and sliding trying to cut skin track. Finally...after almost 3 hours of NO SKI LINES...we made it to the top of the Fat Maid. We were pretty fried, not going to lie. It was more a mental exhaustion than physical...transitioning from booting to postholing to skinning, with no downhill in between. The Fat Maid had been skied by quite a few people before us, but it still looked quite fun. Logan went first, side stepping his way down into the couloir through some initial rocks. Classic Montana feel...

Classic Montana...Beware of rocks. I followed and we looked down the line with anticipation. It looked firm but FUN.

Turn-by-turn, we made our way down the firm windboard. The snow was poor, but the aesthetic was quite good.

Logan crunching his way down the Fat Maid. At the bottom of the Fat Maid, we looked up at Arden Peak. If we were going to continue along on the traverse, we'd have to either boot back up the Skinny Maid, or do some shenanigans along the ridgeline to climb up and over Arden Peak. It was 2 PM and we were both kind of mentally drained. We opted to take our boots off, enjoy the sun, and descend down to the valley through the Maid of the Mist drainage, as opposed to continuing on.

Two ways back up to Arden Peak, where the line "The Pinner" sits. The top variant involves some exposed ridge traversing, whereas the lower variant involves booting up a couloir and then walking the ridge. Here's a summary of our main thought process: Climbing up to Arden Peak via the ridgeline would be slow and tedious. At this point in the day, the 800-900 feet probably would have taken us an hour.It is not possible to ski out of the next drainage after skiing the Pinner. There is an icefall at the bottom. If we were tired after skiing the Pinner we'd either have to finish the traverse or retreat to the Maid of the Mist drainage, where we were currently. It would be very committing.We were wary of the second-to-last line of the traverse, the Second Evil Twin. We had read that the line often involved stepping down over a rock, so we weren't sure if it was in. Given that we were tired, this sounded like a hazard we didn't want to deal with.Finally, steep skiing on firm windboard requires a lot of concentration and effort. Given our mental fatigue, any mistake would be consequential. We both agreed to head in for the day. We had fun, were healthy and not injured...that's a win. We learned a lot and made some mistakes, but none that were costly. Overall, it was time to call it a day.

Purple marks our descent (roughly) out of the Maid of the Mist drainage. The descent down the Maid of the Mist drainage has a reputation for being bushwhacky and messy. It certainly was down low, and we took our skis off at one point and just walked down. Once we made it back to Hyalite Creek, we skated along the trail and skied the luge track back to the car. At what point I nearly hit a pair of hikers on the trail after yelling "WATCH OUT", but thankfully they jumped to the side just in time.

Holy Moly! What a trip. Great report. Fun to read. About the duration... 8000 vert is "not necessarily" a big day for you two?!
