Treasurevault Mountain

Route: Loop: Kuss, Mosquito, Treasurevault
Posted On: 7/9/2023, By: cardgenius
Info: Descent off Mosquito is dry and so is the ridge to Treasurevault summit. The ridge over to Tweto has snow but stay ridge proper and its all avoidable. The big grassy area back to the trail/road has some large snow fields but are avoidable. The road down to the parking area is a mix of dry, mud, large puddles and running water. Prepare to get wet.

Info: Did the loop including London and Tweto. Both roads from the parking area are streams with lots of water. The deep puddle just below the parking spot is still there, and gets deeper during the day. There are some snowfields in spots, up past north London Mine. Ridge to London is mostly all dry and any snow is avoidable. More snow on Kuss, especially on the summit, but rather firm. East slopes of Mosquito still have a lot of coverage from summit, can probably get a 1000 foot vertical run. Most of the unavoidable snow is along the ridge from Treasurevault to Tweto, less while ascending Tweto. Postholed a bit there. I didn't use traction but found poles helpful. The stream in the road going up to the London mine had an iced over surface in the morning. Very windy day.

Info: Treasurevault Mountain today in conjunction with Mount Tweto. Variable conditions; booted up to Treasurevault summit without any traction but trenching was hard work and the snow up there is mashed potatoes. We had everything from sunshine today to snow. 

Route: Loop from West Mosquito Pass

Info: Relatively easy add-on from Mosquito - not as much drop/gain as Kuss-Mosquito but still some good exercise. Was comfortable getting all the way here from West Mosquito Pass winter trailhead in boots but put on my new snowshoes partway up Mosquito for better traction.

Info: We did the Tweto -> Treasurevault -> Mosquito -> Kuss loop yesterday and winter is definitely here. There is between 4" and 2' of snow pretty much throughout the entire route. Two of us wore microspikes for the entire distance, two others took them off at the top of Tweto -- either was probably fine, but bringing them doesn't seem like a mistake. Most postholing can be avoided, but expect to just be stuck down to your knees half a dozen times throughout the route. For pictures, see the conditions report on Tweto.

Info: Cold and very windy day.I did the loop counterclockwise and enjoyed very much going up road 856 until it faded out.There are remnants of a mine there and it is incredible to see steel cables wrapped in boulders.Those miners were something else!. Heading up the upper basin to the saddle to get to the ridge was easy.It is mostly tundra with a few rocks here and there.The streams are covered in a layer of ice already from overnight temps.Going towards Treasurevault was mellow albeit the strong wind and gusts that kept rocking me . The hike from Treasurevault to Mosquito was also enhanced by the wind. Going up Mosquito there are some game trails that one can follow up to Summit.There are patches of consolidated snow in parts of those trails.Views from Mosquito's summit were beautiful but wind was strong and cold.Coming down from Mosquito was quick.I decided not to go up Kuss because of wind and instead walked road to Mosquito Pass and from there hiked down 12 to my car. A real Fall day out there!.

Info: Sorry to have missed the welcomer today, but had a good day in the Mosquito Range nonetheless! Condition notes common to overall route (London Mountain West Ridge + Kuss -> Mosquito -> Treasurevault Loop): Brought microspikes, but didn't use them the entire route. There is definitely snow there, but for the most part it can be avoided and when it can't you're doing some short 4-6” postholes or when hardened the snowfield section is too short to make putting spikes on worth it. Beautiful weather. A lot of the route there was no wind but when it was there it was measured as only 10-15 mph and briefly 20-25 mph at worst. Temperatures measured high 20s to start with but got all the way into the low 40s on the ridges and summits later in the day. Condition notes specifically for the Treasurevault (and descent) part of the route: Heading down from Mosquito to the Mosquito-Treasurevault saddle was the trickiest part all day. We could tell the slope is steep and pretty loose when dry, and for the most part the snow stabilized it all, but closer to the saddle the snow got thinner and the slope got steeper so we had to carefully switchback (snow here was too soft anyway for microspikes). The final ascent up to Treasurevault was then dry and straightforward. Some snow fields we did some short and shallow postholing through on the ridge on the way to Tweto from there. Descending into that basin below Tweto the snowfields got pretty shallow or avoidable. 4WD road back to trailhead was dry for the most part but has some snow in spots.

Info: 4wd road was snow covered in places but we were able to drive to the parking spots in front of the true off road part of mosquito pass. We took the summer trail up to Tweto wearing spikes, left ice axes and snowshoes in the car. We were passed by some guys later on that broke the rest of the trail, thanks! We followed their tracks and cut up tweto before the gully/saddle section. It was steep, deep snow in stops with loose rocks, 2 of us had poles, 1 nothing, she wished she had her axe with her for support. Those guys headed to Arkansas and we didn't see them again. We continued on to treasurevault, mosquito and kuss, making a loop. The ridge was a mix of rock and deep snow patches that were not supportive. We discussed if snow shoes would have helped and decided based on the bare sections we would have been putting them on and off all day or scraping them on the rock. We suffered with the postholing. Spikes stayed on all day, could have used the axe on a few snow fields. The descent off Kuss held some of the deepest snow all day, be careful of the hiding rock, mosquito Pass Road off Kuss was covered in more snow then expected, we stuck to the outside edge where it was less deep. Overall not bad for Dec, lacking snow for sure, but enough to make everything extra work. Get it while you can!

Info: Road is clear to the London Mine TH; it's got some depth of running water in places and is more suited for a good 4WD vehicle with clearance. Hiked London Mountain to the saddle of Tweto/Treasurevault before weather came in. Entire loop is clear of snow on trail - lots of good cornices remain and some snowfields but the exit basin between Tweto and Treasurevault is clean of snow, but wet. Enjoy!

Info: Descent to saddle from Mosquito had about 6 inches of snow covering unstable scree. I stuck to the ridge, wearing snowshoes. Snow on ridge was consolidated. Descent from Treasurevault towards Mt Tweto and down the basin had considerably less snow than when I was here last month. Snowshoes were overkill for about a mile of the route down but I wore them anyway to avoid taking them off and putting them back on again. Snowshoes were helpful and I was glad I wore them.

Info: By far the easiest peak of the Kuss/Mosquito/Treasurevault loop. Descend Mosquito's steep and extremely loose (sometimes practically skiing through scree) north slopes to the saddle. Gawk at the old mining equipment here. Then continue north up Treasurevault's also-loose-but-not-as-bad slopes. You'll see there are a lot of trails snaking and twisting up the slopes, just link whatever you want or go direct, it's about the same amount of effort either way. In fact, sometimes the trails are more loose due to the amount of scree vs the talus everywhere else. 

Route: from Mosquito Pass

Info: Mosquito Pass is currently accessible from the Leadville side. Groomed from the winter closure to the plateau before the first switchback (12,400). Patchy snow beyond that, with 2 large snowslopes that are easily avoidable. Once at the pass, the ridge is completely windblown in both directions.
