Mt. Antero

Route: West Slopes

Info: Didn’t feel comfortable pushing my Subie past the first 200 ft on the trail given the giant, snow-covered boulders guarding the road.

The trail (road) was covered in 1-2” of snow for the first couple/ few miles, and snow depth increased from there. 3-6” of fresh powder consistently below treeline with the exception of drainage areas which cross the road. Above treeline depth increased significantly to 6-12” plus. I did not summit and turned back a few miles from the summit to avoid a prolonged, miserable and potentially dangerous day of breaking trail the whole way up. Did not see anyone else on the trail.

Info: snow in drifts above 12k (from the saddle up)...
the trail has drifts which do leave some space for walking to the left or the right on switchbacks,
Then the final .5 mile gets pretty snowy in places. Microspikes help a lot.

Info: Great conditions today. Minimal wind.Trail is completely dry, only small specks of snow here and there. Opted for the slightly longer route, glad I did as the 15 miles of 4WD road hiking seemed soul crushing. Little Browns was beautiful. Didn’t see any other hikers until I reached the junction of the standard route.

Info: Conditions were perfect! A bit breezy and cold near the peak. Trail not marked once you hit the boulder scramble to the top. Great views.

Info: We decided to take a shot on Saturday given the rain wasnt forecasted until noon. We took the 4x4 to the parking area just below 12,000. The road wasn't bad in the dark, just got out in a couple of spots to take a look at what we were going up, in a mild lifted Tacoma. The hike up to 13,800 was gorgeous, then we ended up in some snow clouds so we didn't get many views from the top. We talked about driving further but compromised that 12,000 was a fair point to knock off miles but also consider it a real 14er summit.

The road to 13,100 is not bad at all it just has some exposure.

The summit push did have some thaw from the night before so there were some slick parts but the trail is still clear of sticking snow. Route finding was also not bad and the trail was fairly compact if you stayed on the route. We had our two dogs who are both well traveled on the trails and they did great but the initial ridge has a couple of spots where you want to slow down and take your time to be safe.

Info: Drove up nearly to the end of the 4WD trail. At about 11,800 ft there is a truck that rolled and a camper that is nearly blocking the remains 4WD trail. There was a Suburban and F150 that somehow got around the camper to park about 200 ft further along the trail. Not worth it IMO. We didn't want to risk getting stuck or sliding off the road, so we opted to reverse down to a flat portion of the trail. On the trail, some snow patches that were avoidable. Good conditions, overall.

Info: Subaru Forester made it nearly to the massive snow drift around 13,000. Rocks get sharper as you ascend (due to less vehicle travel?) did have a sidewall blow out on sharp rocks around 12,800

Info: Similar conditions to the 6/10 update. Camped at 11.5K, there are better/flatter spots across the creek IMO and it's easy to cross. This is a really great route, and if you get out there in the next few days could you please look for my shoes at the TH? I was parked at the end of the lot near the creek and took them off to soak my feet when I got back, can't remember if I left them by the creek or the car. Grey Topo trail runners, I can meet you with a six pack in Summit county or Denver area. Thanks!

EDIT: Got my shoes!

Info: Rode my wheeler up to around 13000 where there is a big snowbank blocking the road. Its huge and prolly will be there at least another month. Two small snow banks below that in which my wheeler could barely pass. The road is extremely rocky with big rocks in places. Not many places to turn around or park. While there are a decent number of places to park, it's limited and some spots are not level. Very high clearance recommended.

Info: Drove my Jeep up to 11,000. Stopped there so I would get 3000 feet elevation change. Drove the Jeep through a pretty good sized river crossing no problem, but was talking to another hiker who got her feet wet crossing this part. It was pretty swift with all the snow melt. There are a couple pretty large snow drifts in the road at about 13,000 that 4 wheelers can't even get past and all the way at the top where there is a parking lot there is a HUGE pile of snow. I could have avoided the snow drifts, but tried walking across a couple and post holed twice. I went in deep and fast so I recommend avoiding.

Info: There's still a little bit of snow that you have to cross toward the top but no equipment needed. There's also snow covering the switchbacks around 13,000 so you won't be able to drive up past that.

I was too much of a chickenshit to take the F-150 over those two massive rocks at the beginning of the 4WD trail so I hiked from the lower trailhead. It took exactly 9 hours round trip.

Info: I did a loop of Cronin, White, then Antero. Antero is almost entirely snow free. It’s melty out there so the road is wet and muddy in places, but only one mandatory snow crossing over the road at around 13k. Lots of people cutting around it off trail, but the right thing to do is cross the snow. Some snow on the upper 500’ that I think covers the easiest trail, but you can avoid the snow and it’s still standard class 2.

Photos are from Cronin looking towards Antero.

Info: Road is dry and passable for hikers for the most part. There is only one snowfield at the final switchback that I cut to get around. Other than that, you can avoid all of the snow up until the mining area. A few sections of the road down below treeline are flooded, so waterproof shoes might be the move. Creek crossings are both manageable. Road is not driveable past 12k at this point. There are a few snowfields on the ridge but the most I postholed from 8:30am-10am was up to my ankles. I don't want to jump the gun, but it's reeeaaaaal close to summer conditions up there.

Info: Antero from Little Browns Creek. The trail is dry until you get to snow fields at 11,700 elevation. The trail runs mostly next to the snow and occasionally disappears into it. However, you can avoid the snow by using the trail or walking on the edge of the snow. The ridge that is the final approach to the summit has some places to walk over the snow. Even at 2pm the snow was soft but firm. I had a light pack on so that could have helped prevent post holing. I never used my microspikes.

Info: Took the standard route from lower trailhead. Snow can be avoided till basically the final ascent to the summit - bless the folks who laid down tracks in the snow because those were nice to climb versus scrambling on the talus! That said, final ascent for sure slower than summer conditions because you really have to check your footing on the snowpack - some spots are quite slick and not exactly where you wanna take a fall up there ... :)Trail runners and poles were great. Left at 6:20a, 6.5 hours. 4x4 road is not the most eventful but those views at the top?? UNREAL
