2016-06-22  Route: East Slopes
Info: Summertime conditions from the trailhead up to the summit. As another poster mentioned, the trail is talus slopes from about 12,000 ft up to the summit. The trail is marked by cairns a lot of the way which is helpful, and an old washed out trail is rerouted to the new trail at about 12,800 ft (follow the trail directions). With all summer hiking, earlier is best! 2 young hikers told us on the way down they experienced static shocks (i.e. Before lightning strikes) during their summit at about 11:15 am. Overall, this was a great hike!

Info: Summer conditions the entire way up - both the road and the trail. Go get it ... if you like lots of rock hopping.

2016-06-13  Route: East Slopes
Info: Road is clear to the last switch back before the section of the road where the trail starts, being blocked by a large snowdrift. Looks like it will be gone in a week or more. Trail is dry besides a couple gully's around 12200, with one major snowfield still holding a lot of snow for about 40 feet in distance. It was easily accomplished in hiking boots, but trekking poles made it easier. Snow was very soft descending around 10:45. I didn't bring my axe and was happy I didn't. Microspikes weren't necessary either.

2016-06-11  Route: East Slopes
Info: Some small snowfields needed to cross between 12,000 and roughly 12,500 feet. Overall the peak is nearly in summer conditions at this point and the snowfields are easily traversed with very minimal postholing. No microspikes, snowshoes or winter gear needed. A lot of people on the route today and it was beautiful conditions on the summit shortly after 8 am. Still some snow up high on Mt. Princeton Rd around 11,500 but nothing that can't be easily walked around. I would suggest parking near the radio tower or shortly thereafter as minimal spaces are available.

2016-06-07  Route: East Slopes
Info: Standard Route is not that bad. With an early start you can cruise up without potholing at all. You will posthole some on the way down but not too bad. I used microspikes from about 12,400 to 12,900 to get across the snowfields on the way up. I used nothing on the way down. Flotation, axe, crampons are not necessary.

2016-06-05  Route: East Slopes
Info: There's a bit of snow on the road from the 4WD trailhead to where the trail splits north over the east ridge of "Tigger Peak". There is also lingering snow on long stretches of the east slopes of both "Tigger" and Princeton, though most of it is on "Tigger". The snow was soft and in some spots was prone to postholing. Much of the upper slope on Princeton itself was muddy and slick, with the usual loose talus and scree.

2016-06-04  Route: East Slopes
Info: Road is dry until about 1/4 mile past radio towers, after that snowdrifts block any further entry. There is one parking spot/pull-off area at the very end where a vehicle should be able to turn around if needed. I drove my Chevy pickup without any issues, although since it was at night, few spots were a little sketchy just because I didn't know what to expect. When we started hiking at 4:00, snow was still solid enough to hold our weight; however it became soft as soon as the sun came up. To access trailhead, follow the road until trail junction. It is easy to miss in the dark, but we were able to find it by using pictures from .com. Later in the day someone made an arrow out of stones pointing to the trail. Instead of following standard route towards Princeton, we went up Tigger first, then followed the ridge to Princeton. Surprisingly we didn't encounter any snow on Tigger, and very minimal snow on the saddle between Tigger and Princeton. On the way back we descended using standard route. There was a lot of snow, the soft and rotten kind. Microspikes, snowshoes and crampons that we brought with us were useless. We ended up following existing postholes. I recommend going back over Tigger Peak to avoid dealing with snow. We didn't observe any wet slide activity.

Info: Road is driveable to first main switchback above radio towers before snow is blocking. A solid trail exists to the summit through snow on the standard route. 50% of the route is snow free. A summit ski is still in. The face is getting thin in spots.

2016-05-29  Route: East Slopes
Info: As previous reports have stated, the road is clear to the campsites. You could drive a bit further up until snow drifts block the road, but there is nowhere to park. We started early (5:30) and the snow was pretty solid until 10 or so when it started to soften up. Would recommend starting early or you'll likely be doing a lot of postholing. I felt comfortable in microspikes - the trail is pretty well packed down but we saw a couple people with crampons too.

2016-05-28  Route: East Slopes
Info: Road clear to camp sites above radio towers. Impassible snow .25 mile beyond last campsite. Significant snow on route on the slopes below Tigger all the way to the summit. Can be done in microspikes for the brave, but crampons highly recommended. No signs of any recent avalanche activity (unlike other nearby areas where wet loose have been prevalent). Expect a lot of time picking your way over the intermittent rock bands that poke out of the snow along the standard route.

2016-05-24  Route: East Slopes
Info: Like previous condition reports attest- the road up to mt princeton is open. I drove my 2007 outback to the radio towers. (should have added another .3 mile to campsites) I drove up during the night and it a weird experience- for sure it takes some skill and conjones to take your medium clearance car up to the radio towers area. the route itself is nice. I climbed all the way in my ski boots. i thought i would be able to ski tour some but that wasnt the case. started 6;15 ( definitely too late) summit at 10 am. Skied down from the summit proper, and went down for 2k. Glorious skiing. I didnt want to leave the couloir early, but instead was punished a gruelling 500 feet climb back to the ridge in wet slushy snow. back car by 12:30. the drive down on princeton road was much easier due to two reasons- gravity and daylight!!!

2016-05-22  Route: East Slopes
Info: Same as yesterday's post, road was clear and dry so we parked just above the radio towers. Snowshoes weren't needed but microspikes were a must. Started at 5:45 and reached the summit by 8:45. We missed the trail and ended up higher on Tigger than we would've like so it took longer. I agree with the previous post, take the standard trail up to the ridge and work your way up. That is the route we took down. It was very windy on the summit (damn near lost my hat) as I'm reading was the case on many other summits today. The hard pack snow was good in the morning up to the top and the whole route down was very slushy and slick (good amount of postholing). Got back to the trail head by 11:00. Looked like the skiers had a pretty good descent (saw about 10 by the time we got back)

2016-05-21  Route: East Slopes
Info: The road is open to the radio towers, there is snow on the road starting just after the towers. Still a lot of good spring snow up there, it started getting soft around 10am. There is no need for snow shoes! If you stick to the regular trail the sidehilling makes snow shoe use terrible. After you get off the road head directly up to the top of the ridgeline and take the ridge to the summit.

2016-05-12  Route: East Slopes
Info: Road is clear to about 1/4 of a mile above the radio towers. Plenty of snow above timberline, spikes are a must and skis would save you a lot of heartache after noon. Wanted crampons on a few spots, but it's manageable. Snowshoes are pretty useless on the summer trail since the snow is so steep. Might be safer and easier to go straight over tiger peak rather than following the summer route. Evidence of small wet loose slides, and a hard slab underneath a thin layer of wind blown snow in the gullies, so be careful if you take the standard route. Tomorrow, the snow will be horrendous to walk on, but doable with skis.

2016-04-09  Route: East Slopes
Info: East face of Princeton is in OK shape. Microspikes would be very handy both below and above treeline on a cold morning. Snowshoes are probably not necessary. Skiing from the summit is OK, mostly type 2 fun, with some type 1 once you get down on the apron. A lot of thin spots and too many rocks up high to connect everything together from the summit to the bottom. The road is not quite ready to drive up to the radio towers. Mostly it is in good shape up until the final switchback, where you can still run into some trouble.

2016-03-20  Route: East Slopes
Info: Just in case you are going up before next week's snow and wind. Usual long walk for our dear underappreciated Princeton, but with a touch. Barebooted from TH to radio towers. Stretches of snow, but nothing more than couple of inches. No need for spikes or gaiters. At towers, snowshoes on, though spikes could do for some before it all softens. About quarter mile from towers, snowdrifts buried the road. That is the touch. Awkward (at least) walking all the way to timberline. And some sections just do not look right, safety-wise. See the photo. Today, it was about 4 inches of powder on top of old frosted layers. If with snowshoes, bushwhack shortcut straight up may seem like better and even safer option. One such shortcut is easy to spot about 200 yards after second switchback going up(counting from towers). Seems that on the way down, somebody (just one set of boot tracks) also continued from that point down to the first switchback, in order to avoid that section shown in photo. Which means that some could as well bushwhack up even from that first switchback, through brush. At timberline, instead of continuing to summer turn-off up the same drifts covered road, see if it is better to go right up the hill (red line) to meet the summer trail on the ridge (see photo). After that, you can see the dry option up the Tigger (which, remember, has a bunch of false summits, so be patient, photo). Just barebooting. Could have taken my summer boots today. Ridge also dry all the way to summit (photo). Alternative is to continue the summer trail, through patches of snow etc. Your choice.

2016-02-21  Route: East Slopes
Info: Left the lower parking lot around 7am. A snowcat packed down the snow all the way to the radio towers. After that traction is necessary. Snowshoes or at least crampons are necessary. We only had crampons and postholed a little, but if it were much warmer, we would have postholed a lot more. There is no packed down trail above the radio towers. We shortcut one switchback on the road where the road looked unsafe to travel. We left the road for the ridge at tree line. The ridge up Tigger is snow free. We summited Tigger then down to the saddle and rejoined the summer trail. The ridge up to Princeton has a few snow fields that can be avoided by going off trail to steeper and less stable sections of the face, but was easier to putting on and taking off crampons every 200 feet. Absolutely beautiful at the top. We summited at 1:30pm. Sunny, low 30s, only a few high clouds, a calm breeze, and amazing views. We took the summer route on the way down. Do not attempt the summer route without crampons, an ice ax, and avalanche experience as there are about 8 steep snow field crossings. Nice hike down from the ridge and along the road. We got back to the parking lot at 6pm.

2016-02-10  Route: East Slopes
Info: The road is closed at the parking lot. There is bootpack trench to the radio towers and snowshoe trench to timberline. I climbed the east ridge, which is sufficiently wind-scoured that snow can be avoided (Photo 1). It was also very windy, so I descended the summer route which looks clean from the summit ridge (Photo 2) but actually crosses several fresh windslabs (ex. Photo 3).
