Info: Started at the Mount Sherman TH at 4:30AM. Trail is dry for about the first mile, then pretty much continuous snow to Dyer. Used mountaineering boots, micro spikes and poles all day, but probably could have gotten away with trail runners if I left a half hour earlier. Snow got crappy around 9:00AM. Summited Sherman, Gemini and Sheridan in addition to Dyer. Perfect, sunny, windless day. 9.34 miles / 4,094' gain / 5 hours, 17 minutes 

Route: West Ridge

Info: Hiked from Leadville, eventually gaining the saddle between Little Ellen and West Dyer. Had lots of small collapses on very low angle terrain, and even in snowshoes was punching knee-deep through a couple of crusts. Gained west dyer, dropped to saddle, and climbed dyer’s west ridge, which was phenomenal fun but took quite a while with punchy snow. I descended north to regain the groomed Weston pass road but not before postholing through an oven. Finally made it back, 12 hour day town to town. It’s worth noting the prevalence of large cornices and a few avalanche scars on leeward faces. The wind a couple days ago really worked the landscape.

Info: Summited Dyer via SE ridge from Gemini/Sherman. One small snowfield to traverse near the summit. All other snow is avoidable.

Info: The west ridge is a great scramble. Mostly solid rock and the major cruxes can easily be bypassed. Highly recommend!!

Info: Road is clear of snow, trail is clear of snow. 100% summer conditions. Wildflowers are just starting. Decided to connect to Mount Evans B and it made for a beautiful day, 5.4 miles and 2850 ft gain RT including both peaks. If you continue to Mount Evans B, there is 1-2 C2+ sections but otherwise lots of grassy slopes and a little bit of talus hopping 

Route: north slope from Mt Evans

Info: Road up to Mosquito Pass has several large snowdrifts and fields to cross, but was fairly firm. From Mosquito Pass, was able to avoid all snow - west side is clear, east slopes from ridge holding snowfields and cornice. Scrambling between Evans and Dyer does not exceed class 3, but may require some route finding.

Info: Some snow crossings but nothing that required spikes or axe - can be 99% avoided. Melting quickly - lots of runoff in the afternoon. 

Route: From Evans

Info: Dyer and Evans from Leadville side today. The snowmobile highway is in great shape, no flotation needed today. The west slope to Evan's ridge was fairly windblown also, it was easy to get up. The short narrow ridge between Evans and Dyer was great fun, really enjoyed it, no traction needed. Warm sunny day with little wind. 

Route: Combo with Sherman/Gemini

Info: Climbed Dyer today with Mount Sherman and Gemini Twins. Fantastic day out - minus some gnarly wind - with mostly summer conditions on the route. Really fun and scenic ridge walk from Gemini to Dyer that has some exposure. There are some random patches of snow but they are easily avoidable and very short. Microspikes were not required today for any of the peaks.

Info: Some snow covered ledges in a few spots but all avoidable. There are several options for climbing through the chimney section. I also thought the crux was a downclimb near the top of the route; I may have missed a bypass but I chose the least exposed way down. The rock quality was surprisingly good and IMO this is a quality, underrated scramble. 

Route: Weston Pass --> Mosquito Pass

Info: Did Weston Peak to EvansB and down Mosquito Pass road as a long ridge traverse... Effectively summer conditions, some snow on Horseshoe and Dyer, but otherwise dry. 

Route: SE Ridge from Gemini/Sherman
Posted On: 6/10/2023, By: madmattd
Info: Traversed over to and from Dyer from Gemini/Sherman. The ridge in the saddle is passable right now with a mix of bare rock and patchy snow. There are some minor wind ridges formed along the cliffy SW side, staying just NE of the ridge crest worked fine with spikes and ice axe (latter not strictly needed) and a little care. I don't think the snow in this spot will be an issue much longer. The steep slopes above the power lines are all well-filled in with snow, a direct ascent with spikes and the axe was fine with nice styrofoam snow before 9 on the way up, and only slightly softening shortly after 9 on the way back. I think they'll be around for a while yet. I glissaded a couple of the upper stretches down to the power lines, great fun. A set or two of day or two old ski tracks came up/returned from Iowa Gulch to the summit, snow coverage up high looked good, not sure what it was like down lower in the gulch though.

Info: Leaving West Dyer and ascending Dyer the ridge starts right away with needed route finding. Started as fun scrambling then in the middle became pretty sketchy with loose rock in saturated dirt from all the moisture at times finding it difficult to maintain three points of contact. There are several different lines one could take. We were fortunate that it didn't start raining til we were off the difficulties. From there we went to Mt. Evans B. Returning to the same spot we continued up Dyer's ridge, now only Class 2 rock hopping the remainder of the ridge. From Dyer's summit (39 degree wind chill) we descended and headed over to Gemini.
