Route: Southeast slopes
Posted On: 2021-12-20, By: spapp
Info: Light snow drifted onto Lawn Lake trail approach. Bit deeper snow on Black Canyon trail and bushwhack through trees. Alpine section free of snow. Very windy in agreement with wind gust forecast. Herd of bighorn at 12,800 enjoying the day, too.

Info: The southeast slope route is free of snow with the exception of small patches on the main trails. We brought microsoikes, but they were unnecessary. 
Route: Mummy Madness from Lawn Lake Trailhead
Posted On: 2021-07-12, By: supranihilest
Info: Take the excellent Lawn Lake trail for approximately 5.6 miles then turn right/south onto the Black Canyon trail and take that for 0.4 miles before heading north/northwest into the forest at an approximate low point on the ridge. Head north through the forest to treeline and then up Class 2 boulder-strewn slopes to the summit. No snow on the route, some mud and running water on the trail.

Info: Route clear to summit, no issues and a pretty straightforward class 2 (if exhausting). Summit log dates to 2016. No issues except, maybe, the confusion over the part of the route in the trees and a marked route. To be clear, there is no marked route on the tundra section of the climb (nor should there be; route finding is pretty straightforward); it is just in the trees where one helps. Basically, there is a pretty well-worn and heavily cairned route up the steep stretch in the trees to the edge of tundra, though it is easier following it down than up. The bottom is a sandy flat at 40 27' 30"N 105 37' 01"W with a large cairn. The last cairn at the top is at 40 27' 35.5"N 105 36' 55.1"W just west of the knob mentioned in the route description. Over that 220m (720') horizontal you rise 320', a steep grade in trees. Getting to the base of that climb from the Black Canyon Trail is the trick. There are some routes from the Black Canyon Trail; these are less obvious; I didn't find the one in the description. In coming's down, a set of cairns led from the sandy flat to a trail that parallels the moraine ridge defining the high point on the Black Canyon Trail. There is a cairn above that trail very near the top of the trail at 40° 27' 27.8"N 105° 37' 06.8"W (near one of the trees across the trail; cairn is barely visible in the attached photo). If you turn off the trail there and cross to the east side of the ridge, you should find the trail leading left (north) and then east to the base of the steep part. Worth noting that even with the low use in this area, there are some places where wear on the tundra is showing despite a high range of options on the ascent. Groups should avoid traveling in line as multiple footsteps in a year will kill much tundra. 
Route: Southeast slopes

Info: Only a few remaining small snow fields in the tree section, and one on the SE ridge. Many downed trees in the tree section, but the rock cairns help guide up or down through that section. Recommend going a little farther on the Black Canyon trail before headed in, compared to the route description. This is also where the rock cairns are. When heading down, you turn right at this rock formation at tree line. I think this formation should be named "sleeping dog rocks".

Info: I encountered a little snow on the trail after the Black Canyon Trail intersection, but it was negligible and easily navigable. Otherwise the entire route is snow free. 
Route: Southeast Slopes, Northwest Slopes (to Hauges)
Posted On: 2018-08-12, By: supranihilest
Info: I traversed the full Mummy Range and thus did not climb down any route I climbed up. Keep that in mind when reading these Mummy Range conditions reports. Southeast Slopes: From Lawn Lake Trailhead the trail to Mummy Mountain's southwest slopes is fantastic. Easily one of the best trails I've ever been on. The turnoff for the Black Canyon Trail near Mummy Mountain is obvious and signed but the turn to make your way to Mummy is not obvious. I went a few tents of a mile down the trail and simply walked into the woods, towards a saddle. The photos on the route description show a big rock and I'm not sure it's 100% necessary to find, since I don't know if I did or didn't. In any case once you break through treeline the route is very obvious and turns into mild-then-steepening class 2 tundra and talus hopping to the summit. Northwest Slopes: Basically identical to the southeast slopes, just in the opposite direction. Hagues Peak is left on the ridge line across the saddle, which is a wonderful alpine meadow. This was an easy and enjoyable part of the climb. 
Route: SE slopes via Lawn Lake to Black Canyon
Posted On: 2013-05-27, By: krishcane
Info: Lawn Lake approach trail starts major post-holing at around mile 5 in the morning or mile 4 in the afternoon. Snow around Lawn Lake itself is messy and deep still, though snowshoes probably would make it fun again. Above treeline on Mummy‘s SE slopes, snow was all avoidable until the summit and well consolidated there.
