2015-07-03  Route: East Slopes
Info: Early morning fog along 24 with low clouds in the morning from 4:00 AM to 6:00 AM. One small glancing blow from a storm immediately west at 8:00 AM, giving way to clear skies well into 1:00 PM with some scattered clouds. The trail is dry and clear with two short snowfields and one narrow mudslide approximately ten feet wide.

2015-06-28  Route: East Slopes
Info: Trail is nearly dry all the way to the summit. Only two small snow fields remaining. We carried traction and an axe but didn‘t use either. We hit both on the ascent around 745 and 800 am respectively. At that point they were both still solid but could be easily navigated with poles and some care. On the way down they were soft enough to easily walk across without much thought. If you are up there super early they may be icy enough for an axe. Other than that its totally dry to the top. Summer has arrived.

2015-06-27  Route: Southwest Ridge
Info: The ridge to Princeton from the Grouse Canyon approach still had one or two short sections of snow that was not avoidable (steep loose scree on either side). Should be gone soon.

2015-06-27  Route: East Slopes
Info: A few small snowfields to cross. Along the ridge the snow is avoidable. Trekking poles or micro-spikes might be useful. Snow was already slushy around 6am, so I suspect we don‘t have too long before the trail is snow free.

2015-06-23  Route: East Slopes
Info: The road is dry to 11,200‘ and the trail is dry until it intersects snow fields on the north side of Tigger Peak. There are 4 or 5 to cross and a fall on early-morning hard snow could be a problem, so an axe is recommended. The 12,800-foot turn-off to gain the ridge is not obvious right now because of snow and some people have been following the old trail all the way to the east face. Once you‘re near 12,800‘, look up to your left for tracks and trail segments to locate the trail so you can stay on the easier, standard route. Once on the ridge, there are only a few snow patches on the remaining hike to the summit.

2015-06-21  Route: East Slopes
Info: The route over Tigger Peak is doable with no equipment. Just start early so the snow stays solid. Bluebird skies all day! We camped at the last available camp site .3 miles past the radio towers on mt Princeton road. You can drive up from there past the first two switchbacks before snow blocks the road, and skirting it on foot is no problem. From there the road all the way to the ridge and the hike up Tigger is snow free. You will have to walk across snow in a few spots along the ridge to Princeton but it is super easy. I brought gaiters but didn‘t use them on the way up, and only postholed 3 or 4 times. Most of the snow up the ridge to the summit is avoidable if you stay on the ridge and keep left of the snow. The final ascent is snow covered but you can follow the boot tracks and easily walk to the summit. The way down was another story entirely. We should have gone back over Tigger, but instead we descended via the standard route and spent 2 hours slogging our way through the rocks and snow until we made it out onto the tundra and the trail was finally just dirt. Definitely bring gaiters and an ice axe if you go that way. The snow is melting fast so conditions will change rapidly, but for now there is still a lot of it on the standard route. If you go up and down via tigger peak you won‘t need anything but gaiters.

2015-06-13  Route: East Slopes
Info: Princeton was in descent shape this morning. I started by going over Tigger but decided that the snow conditions looked ok to decend the standard route. Snow is settling down and the slides i saw looked to be caused by climers I was postholing from about 7:30 on. Snowshoes or microspikes could of helped but mountain boots and an axe got it done. Start early and have fun.

2015-06-03  Route: East Slopes
Info: Summary: Drive up to radio tower, dry road almost all the way to the Princeton trail, then deep wet snow immediately thereafter all the way to the summit. Trail Info: Doesn‘t look like anyone has been up in awhile. Old ski tracks all covered in avy debris. Remains of a trench going up "Tigger Peak." We put a trench up to Tigger if you are attempting Princeton. We parked at the radio tower (though you could go a little further to the campsites), but immediately after the campsites 3/4ths of road is covered in deep snow. It was generally dry up to the last switchback before the standard summer trail leaves the road, but we departed the road at the switchback following boot and skin tracks. We followed the ridge up to where it joins the standard trail so we could avoid crossing an avalanche gulley for a second time. From there we put on snowshoes and put a trench directly up the ridge to "Tigger," removing snowshoes at about ~13,000‘ for a rocky section (and then bootpack to the summit). Snow Conditions: Sketchy snow conditions, I don‘t know if I would traverse across "Tigger Peak" like the standard trail has, almost everything on Princeton has run except that face so take that as you will. Avalanches in just about every gulley, chute, and bowl above 11,500 feet, including debris burying several different sets of ski tracks coming off Tigger and Princeton (as always, don‘t be fooled). I don‘t think anything below 13,000 feet has gotten a serious freeze in a couple days, but there were parts above 13,000 feet that were a lot more supportive. However, with 50 degree temperatures at the summit of Tigger.... Anything you would want to ski is in right now, but either do it very early in the morning or wait for a more stable date in the future. Snowshoes were somewhat useful for about 1,000 vertical feet (would have rather had skis) but debatedly so. Fun sections of post hole hell no matter the time of day. We didn‘t push our luck continuing on to Princeton although the ridge seemed safe enough. Maybe if it was four hours earlier in the day. Seemed quite doable.

Info: Road is clear to the signal towers. We got in Friday night, grabbed a few winks, then woke up at 4:00 AM and started the hike. Snow present basically the entire way once you hit the trail off the road. Avy danger almost non-existent. Bring some microspikes and have some fun. It‘s a great hike with great weather this time of year.

2015-04-06  Route: East Slopes
Info: Parked in the TH parking area. Was able to wear trail runners past the radio tower. A Ford SUV made it to 10,400‘. No flotation or spikes needed until you leave the trail at 11,800‘. The stairs indicating the start of the trail are covered and not visible. The summer trail still has plenty of snow. There are three steep snow fields that must be crossed. Spikes and an arrest tool are highly suggested. As the snow warms it gets very loose. At 12,500‘ I turned and headed down. The last steep snow field was very loose and I chose not to continue. Sorry no pics, my phone died.

2015-03-21  Route: East Slopes
Info: We parked at the Mt Princeton Road 2WD trail head, and starting at 7am we hiked up just enough snow pack to the end of the 4WD road with just our boots on- no flotation needed. At this time we put on micro spikes to help our ascent up Tigger. There was one other climber on the mountain who decided to take the East face of Tigger, and we then decided to take the North face of Tigger to get to the ridge line. We stashed our snowshoes at this time as we realized we would not need them at all this trip- lots of snow has melted. There is not enough snow to warrant taking the switch backs west to the normal winter Trigger trail. Even still, climbing Tigger on the ascent to Princeton, and then climbing it again, and then going back down it during the descent- were the hardest parts of the route. Within another couple weeks, without another big snow, this mountain will be even more bare and ready for summer.

2015-03-15  Route: East Slopes
Info: Hiked up from the winter trailhead. The first 3 miles to the summer TH were packed snow and really easy to get up with just my trailrunners. At the top of the road and the summer TH, snoweshoes were pretty much mandatory. I skipped tigger and hiked around, but I think it may have been safe from avalanche danger either way. There‘s not all that much snow cover up there. Check the recent snowfall and princeton is a good one to knock out in the winter, just make sure you‘re prepared for a good long trek. Started from the bottom of princeton road at ~8:30, and returned to my car just before 2:30 pm (had some fun running down in the snow).

2015-03-14  Route: Tigger
Info: Lower TH to upper TH was not so bad. Microspikes were not really necessary although I went ahead and used them. From upper TH, we used snowshoes and switched back to microspikes before we started scrambling up Tigger and all the way to the summit of Mt.Princeton. There wasn‘t very much snow even on the summit and coming back down Tigger a lot of it had melted. Long, strenuous day but a huge accomplishment for us. Weather could not have been any better. It was a blue bird day!

2015-03-06  Route: East Slopes
Info: Wheeled vehicles park in the lot at the base of the road. I followed the road to the beginning of the summer trail with one exception; I shortcut the final switchback, climbing the edge of an older field of avalanche debris (photo 1). The one other avalanche concern was a large, unavoidable snow field between the road and the base of the east ridge. It was stable for me (photo 2). Once on the east ridge, both the climb over Tigger (photo 3) and the ridge to the summit (photo 4) can be done while avoiding avalanche danger. The road had about 2-6 inches of fresh snow that largely filled existing trench (snowmobile to the radio towers, foot travel beyond that). I found snowshoes to be useful on the upper part of the road and on the climb to the base of the east ridge. Once on the ridge this is a talus climb intermixed with bits of snow; no winter tools beyond gaiters were needed. There is surprisingly little snow on the mountain at the moment. Photo 5 shows the summer route covered by snow fields in places and clearly visible in others.

Info: There was enough snow to cover most of the trail, but not enough for much avy concern. We were able to stay on the standard summer route without going over "Tigger." It was close, though. After this recent storm I‘d assume Princeton is now in full winter condition with a traverse of "Tigger" being prudent. No snowshoes required on our climb, but again, that‘s likely changed. Slightly under 11 hours RT from the 2WD TH. link Blog post/trip report with additional information.

2015-01-26  Route: East Slopes
Info: No avy danger on the standard summer route as of this climb. 4WD road has a boot/snowshoe track all the way to where the Mt. Princeton trail cuts off at 11,800‘. The Princeton trail is buried only for a short distance (maybe 50 vertical ft) heading up to the shoulder. The portions of the traverse trail that sees no sun (most of it) is covered with slick compacted snow/ice. Microspikes pretty much a must all the way to where you leave the traverse trail (about 12,800‘) in order to mount the high ridge. Talus climb to ridge mostly on rocks. Ridge climb to summit mostly blown to exposed ground. Snowshoes not needed at all on this trip.

Info: I tried Princeton today. New snow at the trailhead was about 3" and increased to 6 to 8" above the towers. When I got to just before the turn off, there were several big drifts across the road (11,650). They were, however, more than drifts. They were like pillows with a fair amount of snow running 100-200 vertical feet above them. I did a quick hand pit on the first one and found it to be an eight inch soft slab on top of at least that much soft, unconsolidated snow. This was obviously created in the recent storm and wind event. I would have only had to go 50 ft to get past the first one but this was not what I was looking for at this stage of the climb. I cannot tell what was beyond this but if there is this kind of loading at this stage in the climb I can imagine there is more as you get higher. The Avy report yesterday mentioned that there was considerable wind in the recent storm in the Sawatch. I agree. I will try to get pictures up asap but this is not easy on my motel wi fi.

2015-01-18  Route: East Slopes
Info: The road to the communication towers is snow covered with ATV and snow mobile tracks. There are icy patches and sections that are completely bare. The camp locations were pretty much bare. If you plan to camp, the third spot about 500 yards past the towers on your left is the best IMO. Once past the towers, there is quite a bit of drifting across the road. Most of the time the edge of the road was clean or the snow was hard enough to walk on top. Micro spikes were absolutely perfect for the conditions. The start of the Princeton trail at about 11,800‘ is not easy to see but getting to the ridge is not too difficult even if you are off trail. Once on the ridge, you should have no problem picking up the trail. The East Slope traverse was packed snow and bare. Once again, Micro spikes were very helpful. The avy danger was pretty much nill as shown in the photos.

2015-01-16  Route: East Slopes
Info: Recommended gear: microspikes, poles, face coverage! Unless you are on an ATV, I wouldn‘t attempt to drive up the road from the lower trailhead. I got all of 0.2 miles in my 4WD Tacoma and it was obvious it wasn‘t a good idea. You‘ll find the road to the antennas with either a good packed track (from the ATVs, and even a SnowCat, I think) or, on the south-facing slopes, a dirt track. From the antennas to the trail turnoff, there is enough of a packed track to not need snowshoes, although you‘ll have to negotiate a few sections of drifting snow. The trail turnoff is not obvious (buried by a drift). I passed it up and made my own way up toward the lower shoulder of Tigger. Maybe 50 feet above the road I immediately saw the summer trail off to my right and just walked over to it. The traverse below Tigger is OK, on boulders or packed snow. The three gullies had drifting snow but no serious avy danger (IMHO). Another big dump could change that, though. The climb up to the ridge from where the traverse sort of fades out was kinda miserable as was the boulder/snow climb to the summit (I was trying to stay out of the wind so probably didn‘t take the best route, which is mostly on the ridge itself.) So, for now, I think the Princeton trail looks good. It‘s a long hump, though, from that lower parking area all the way up and back--it tuckered me out!

Info: The road up to the radio towers does not have deep snow on it, and in places there is no snow. However with the recent dips in temperature you need chains and a decent 4x4 vehicle. The snow is not deep in most places, but it is the consistency that makes it hard to drive up. We walked most of the way from the first trailhead. The trail itself was mostly clear of snow, there is no avy danger at the this time. Much of the route is iced over, but still passable with care. Beautiful day, not too cold. The wind on the ridge is a little brutal if you are without a balaclava. All around good day though!
