Marble Mountain A  
Condition Updates  
Route: Northeast Ridge
Posted On: 2022-06-20, By: Laxer04
Info: Countless downed trees on the faint trail past Rainbow. According to a local in town, this is the case for many of the trails in the area after a rough winter. Route is completely snow free to the summit. We had a ton of wind and clouds today, but had the mountain to ourselves.

Info: Lots of snow in the Sangres after the last East slope storm. Got our money's worth on the trench as had to put it in from the winter closer. Northeast Ridge was very windswept once finally out of the trees but the snow beneath treeline was deep

Info: Flotation is required for nearly the whole route until the last 500 feet or so. Deep snow even above treeline, but no signs of warming or avy risk. The three of us followed a good trench up to the Rainbow Trail junction and made a new one from there to the top. If you've been wanting this Peak, go get it and enjoy our trench!

Info: Refreshed Colin's trench which was faded in spots. This is overall a very straightforward hike - follow the road up from the 2WD lot (you won't be able to drive to the 4WD lots now - see TH status update) then turn at the large obvious sign for Rainbow Trail with the tall glowing reflectors marking the start of the trail. That takes you up onto the ridge, then it's one long, semi-straight slug up a ridgeline. This is a pretty safe route for an iffy day like today with crazy strong winds in the morning and snow in the afternoon - there's really no exposure to speak of and route finding doesn't get much easier than this (even better when someone else already put a trench in!). I easily booted up to Rainbow then put on snowshoes but at the moment there's a pretty solid trail in place - might possibly almost get by without them if you don't step off the trail, but probably better to have them. Lots of bare ground a little above treeline - could have stashed the snowshoes but left them on for traction/laziness.

Info: Booted from 2WD trailhead to Rainbow trail where a strong trench continued to Humboldt. No such luck for Marble; I put in a trench to treeline. The winds really picked up beyond 12000 and occasionally visibility was very limited. Turned around a half mile from summit. May go back if weather holds out to take advantage of the trench; if I don't hopefully someone else uses it.

Info: The road up South Colony subaru-able - areas of snow were only 3-4" deep at most. We parked right below the Rainbow Trail intersection and began hiking up the road. There was minimal partial coverage on the Rainbow Trail and Marble Mountain Trail until treeline, some parts were completely dry. The descent from the 10,700' point to the base of Marble, described in the route, is very minimal which we appreciated on the way out. The route above treeline was mostly dry and snow patches were easily avoidable. Humboldt was looking bone dry across the way. Beautiful day with sun and low wind - but snow is coming! 
Route: South Ridge from Music Pass

Info: Marble Mountain is almost free of snow. Trail to Music Pass from the east is effectively clear of snow. Did not use spikes or axe all day.

Info: Large snow drifts beginning at 10,800. Snow ends near tree line around 11,600. Snow was compact and supportive, even at 11am on descent. Lots of downed trees on trail below 10,750 but always a decent workaround.

Info: Slept in car at 2wd parking area and started hiking from there. Road is drivable for 1.08 miles at which point snow begins. Snow patchy to forest boundary and continuous from there to Rainbow Trail. Used snowshoes starting at Rainbow Trail up to treeline, approx. 2 to 2.25 miles of shoeing each way. Snow depth averages 2 to 4 feet on top of the ridge. Snow free above treeline. 
Route: Southeast Ridge

Info: Did from Music Pass. Had to park 2 miles from Grape Creek TH due to snow drifts. Don't recommend going even that far unless you have good 4wd. Was able to boot up to just below lower Music Pass parking lot due to packed snow from snowmobiles. From there broke trail w/snowshoes all the way to Pt. 12,739. Stashed snowshoes there then booted rest of ridge to Marble. Didn't need traction, had axe but wasn't absolutely necessary. Snow on ridge from pass to first point was getting wet but still mostly supportive 11-12:00 or so on way down w/approx. 45 deg F temps.

Info: Parked at 8,600 feet, below the 2WD parking. Saw nobody the entire day, but followed the trench along the standard route that was put in yesterday -- it's in great shape. Views of the surrounding 14ers and 13ers are incredible right now. Stashed snowshoes at tree-line and didn't use spikes at all, as there is plenty of bare ground on the tundra. Windy up there today, but thankfully sunny. Quite warm for much of the hike below treeline.

Info: Had to park a quarter mile or so below the lower TH due to snow. Put snowshoes on right away and kept them on all the way to treeline, spikes from treeline to summit but you could get by without. There's now a trench, although I don't know what kind of mindset I was in on my way up this morning because I noticed upon descending that I took a pretty meandering and inefficient route. It'll get you there though. Blue skies, zero wind, warm enough to spend an hour on the summit. I'll add pics in a sec of the surrounding area.

Info: Road is packed to the Rainbow trail and ideal for spikes. From there we broke trail to around 11,000ft and turned around after 4 hours of trenching in knee to waist deep powder. The trenches in the last conditions are gone after the last storms. Will need snowshoes from the road to treeline even on our trench. Snow depth is probably over 4 feet the entire ridge to treeline.

Info: THANKS for the earlier updates, they were VERY helpful in preparing for my hike. There's a good trench up South Colony Rd to the Rainbow Trailhead. Once off the Rainbow Trail and on the Marble trail you will need snow shoes. The trench is not capable of holding you with just hiking boots and micro-spikes. I tested the trench at times and it was as deep as my trekking pole. The wind above and below tree line makes staying on the path difficult as well. Above tree line and on the side of the mountain you can switch to micro-spikes. The wind was another factor. Going up the wind was ferocious, but coming down I needed my trekking pole to help keep me upright at times. It was great to back below tree line to cut the wind. Managed to get back to the road before dark, but needed my headlamp to get back to the 2 wd trailhead. Excellent training for winter hikes.

Info: Snowshoes are a must. The road is hard packed for two miles to the Rainbow trail turnoff, after that I put snowshoes on. The trench still exists to just beyond Pt 10725 (thank you to those who put that in!) After that, I have a hard time believing any trench can survive the wind blasting it away from there until treeline at 11500'. My tracks from the morning were almost gone on the way down. Expect deep snow and wallowing in some places. Above treeline is mostly wind blown with some hard snow patches. It should have been an easy cruise to the summit and back except for the wind tossing me around like a rag doll. My watch said 10.9 miles round trip from the lower south colony lakes TH.

Info: There is a lot of snow up there. Post holing up to our knees even with snowshoes. Flotation absolutely necessary once you get onto the rainbow trail. We put in a solid trench to about 10,900 where we had to turn around due to being completely over it. Beautiful day though. Go get it!

Info: Pretty good path partially up, but then stopped. Made a new path to tree line where the snow ended, but I'd still bring snowshoes. Last part to summit the snow could be avoided. Great views

Info: Summer conditions. In the event that you're considering climbing Marble on the way to South Colony Lakes and descending down the east slopes of Marble back to the trail to South Colony Lakes instead of going back down the ridge of Marble to the Rainbow Trail, don't. It involves cliffing out several times combined with class 3 bushwhacking.

Info: There is a large snowbank right at treeline. Other than that, 99% free of snow.

Info: Generally, patchy snow in the low 11,000' range and continuous snow in the upper 11,000' range. Dry above and below that. We carried snowshoes but didn't use them. At around 8:00am on the ascent, all snow was supportive. At 12:00pm on the descent, the upper reaches of snow were supportive, while the lower reaches were not, but the postholing wasn't bad.
