"Mountain Boy Peak"

Route: Indy Pass
Posted On: 7/19/2026, By: dwoodward13
Info: With Igloo. Highly recommend the wrap around route in a TR posted by d_baker. Really nice route that avoids the awful looking choss on the more direct route from Igloo. Watched 3 folks have a heck of a time trying to connect the two before bailing. Adds maybe an extra 400 vert. 

Route: From Graham Cracker Gulch

Info: Nice day on Mountain Boy and Igloo yesterday, the Teddy Graham trail was well trenched until I broke off towards Mtn. Boy's East ridge. I initially went up the wrong ridge (#World'sWorstRoutefinder), after gaining maybe 800' and checking my position I realized my mistake, was able to cut across and get to the ridge I intended, cost me maybe an hour. Trenching was pretty average, got deeper the higher I went but never difficult. Left snowshoes at treeline, easy walk from there. I hadn't planned on doing unranked Igloo, but figured I could have 1 more beer if I did it. Tried to go straight up the ridge, apparently that doesn't work, sort of meandered around some gullies and made it to the top, found the easy way down. Nice weather Sunday, wind was far lighter than forecasted, it was great.

Info: Took the low route since I had igloo already. Little bit of snow in the second gully to Igloo/Mtn Boy saddle. Descending bulletproof dirt while descending that area made me wish i put on microspikes. Butt scooted down it but was a sketchy 20 feet even with poles. Epic views in all directions

Info: Ran up to Igloo Peak and then dropped far down to cross over to Mountain Boy. There are some higher angle snowfields that we didn’t have adequate traction for (axe for safety and spikes probably sufficient) so we were unable to cross up high and picked our way through some short talus fields to gain the saddle via a goat trail. Slopes leading up to MB from the saddle were grassy and mellow, with epic views of La Plata.

Info: You'll want snowshoes until you get on the ridge leading to Igloo Peak. Once on the ridge, the snow can be avoided most of the way to Mountain Boy Peak, From Igloo's summit, continuing on the ridge toward Mountain Boy Peak looked a bit sketchy, so we dropped a couple hundred feet SW and contoured back to the ridge. This involved crossing a small (perhaps 30' wide) but steep snowfield, so make sure you're equipped to do so safely. 

Route: From Independence Pass / Igloo

Info: This peak is just a short distance beyond Igloo, but I spent a considerable amount of time navigating the scree and loose rock. Likely I traversed a bit too high, despite backtracking as others recommended- the loose slope is really sketchy and slow going, be really cautious. Eventually I dropped to around 12450' where it was a bit more stable. I ascended a grassy slope until it met up with the braided trails heading to the summit of Mountain Boy. I can see why this one is rarely climbed in spite of being likely within earshot of Independence Pass.

For the descent, I headed back to the saddle nearest to Igloo, then turned sharply right down a goat path, and navigated a somewhat more stable talus slope to descend to Mountain Boy Park for a pretty level traverse. Eventually I angled back uphill towards the main trail. Solo summit, didn't see anybody else up there or on Igloo. I was hoping to see some of those rad Mountain Boys up there, but alas, no. Just a couple of mountain goats. Still decent wildflowers up high.

Info: Summer conditions except for one slightly obnoxious bit of snow traversing near the saddle. The dinnerplating coming off igloo does in fact really suck, and if you dont find the goat paths through it you will be sliding all over the place and bringing large piles of volcanic crap with you.

Info: Summer conditions, no ice or snow on the route. Reversed back and down on Igloo and traversed faint paths contouring around through the loose rock toward the saddle between Igloo and Mountain Boy Peak. Dropped into Mountain Boy Gulch on the return. The strip of snow reported in July conditions is much smaller and gaining the ridge is easy. We ascended a notch in the rocks to the right of the remaining snow patch.

Info: As others have noted the ridge from Igloo directly to Mountain Boy is riddled with cliffs and loose rock on steep, exposed terrain. I took the "standard" approach of reverse a short distance back on Igloo and then did a descending traverse on kitty litter rock until I could see the Igloo-Mountain Boy saddle and then followed faint pathways through the loose rock. From the saddle to Mountain Boy is straightforward.

For the return, I dropped down into Mountain Boy Gulch, which is brimming with wildflowers. There is a long strip of snow that makes it a little tough to get back up to the ridge with the Igloo trail, but I kicked in a few steps and managed just fine.

This is a beautiful hike and works well when we have these short windows of good weather. I stayed dry all day, but the heavy hailstorm hit just as pulled into my garage this afternoon!

Info: I did not summit Mtn Boy but from Igloo's summit I could see it was also dry Summer Conditions all the way to the summit .
I did drop on Igloo's southern saddle on a faint goat trail in between the false Summit and Igloo's that contours the shoulder and it was ok.Kitty litter on this steep slope but with microspikes I had traction and felt fine. I dropped down maybe 200 feet before I headed back up. Be aware that if you choose to drop into Mtn Boy Park as suggested on some TR (alternative route) from the trail there are still many cornices with quite a bit of snow.

Info: Dry. Confirming that the ridge direct descent off of Igloo > Mountain Boy is a loose pile of poopy. I took a lower traverse on the way back. Stats in last photo.

Info: Did Igloo and Mountain Boy from Indy Pass. I was surprised how much snow there still was given how little was present on nearby Rinker last weekend. There was next to none on the trail to Igloo but my plans to drop down to the shelf below Igloo were foiled by continuous steep snowfields all along the slopes going down to that shelf with large cornices and/or snow walls near the top of most of it. For getting to Mountain Boy, I took a route similar to headsizeburrito and justiner; dropping a little to the right along some mountain goat trails but not too far down. Crossed one steep snowfield with spikes and ice axe - was able to kick steps in so that a pair behind me was able to follow without special gear. (Turns out it was USAKeller and someone whose name I neglected to write down - fun to meet and chat on Mtn Boy and snap photos of the mountain goats). Mtn Boy was basically dry. The other two retraced their route while I glissaded down the saddle between the peaks. Snow going down and through and along the shelf was mostly solid but occasionally postholed to my knees or more. Used ice axe and kick steps to cross a steep snowfield - almost went up to the ridge on a snowfield but the nearby cornices were making me nervous so I went to the far end of the shelf where there was steep snow but no cornices and got up it to the main trail. Not sure how the photos ended up out of order... 

Route: Loop from Independence Pass

Info: There is a mandatory snow crossing on the back side of Igloo. Otherwise, route is dry to summit. The saddle between Igloo and Mountain Boy is corniced with one exposed rocky section that we downclimbed to descend into Mountain Boy Park making this a loop. No summit register. 

Route: from Independence Pass, via Igloo
Posted On: 6/4/2021, By: mijoflynn
Info: Lots of snow for the first mile -- softening but mostly supportive at 6:30, thigh-deep postholes back at 10:00. I don't know that snowshoes would have made much of a difference. But it's so soft that I can't imagine it will survive another couple days of sun.

Once you're on the ridge, the trail is clear to the summit of Igloo.

I backtracked and then sidehilled around Igloo, rather than trying the class 4 downclimb. The northwest slope of Igloo is clear of snow, and there's a nice trail that takes you down and around. The southwest and southeast slopes have lots of snow, but at 8:00 (up) and 9:00 (down) it was in good condition to kick steps. I descended farther than I wanted to, down to around 12,450', and had to climb back up to the Igloo / Mountain Boy saddle. But that might have been a good thing, since on the way back it became clear that there's a cornice higher up on the ridge that divides the NW and SW faces (at ~12,600') that would have been awkward to get through. There was some rockfall during my traverse.

There's no significant snow from the saddle to the summit of Mountain Boy. Great views. Beautiful day.

Info: Drop off the south of Igloo to avoid the ridge then traverse to the saddle where its an easy walk tot he summit. Descended by 12542 which is relatively steep by manageable.
