Diamond Peak - Glissading Heaven!  Sucess!

Came in from Carrigan Lake and had the whole mountain to myself. A classic Cascade cones with the summit being hard to pick out until you get near the top. One of the best glissading adventures down I've ever had!

Southwest Ridge  Sucess!

Snow level at 5,400 feet. Skinned and then hiked up with crampons from 6,800 feet or so. Great run down the west bowl and great views.

Up the S ridge, down the SW ridge  Sucess!

Started at the Rockpile Trailhead, then went up the "normal" climber's trail (via Marie Lake). Descended on the southwest ridge, planning to continue SW until we got near the junction of the Pioneer Gulch Trail and the Diamond Peak Trail. But instead, we left the ridge at about 6700' and bushwhacked SSE back to Marie Lake, because it was hot and we wanted water to swim in and drink.

Unique, low-traffic mountain  Sucess!

Diamond Peak is my yearly early-season tune-up/conditioning climb. It's a great peak with a beautiful summit ridge. You can often catch butterfly migrations in early July. You will also get eaten alive by mosquitoes below treeline in the early season, so bring your repellent and head net if you're going in June/July.

Beautiful backpacking weekend  Sucess!

We backpacked into Marie Lake which was beautiful despite some mosquito visitors. Nice and easy with an opportunity for a long afternoon snooze. Hiked up Diamond Peak which was pretty strenuous. Hike out the third day. Very humane itinerary.

Diamond Peak Ascent  Sucess!

Climbed Diamond Peak on a sunny day. Views to the north were excellent with visibility all the way to Mt. Hood with Jefferson, Three Sisters, and Mt. Bachelor in between. Visibility south was limited due to wildfires near Crater Lake. Check out the video here: https://youtu.be/N_7C1kPkWQ0

2nd Time is the Charm  Sucess!

After trying and failing on this mountain a few years ago (it wasn't a very serious attempt, since we randomly decided to have a go at it), I found an opportunity to return. Solo hiked from the junction of the PCT and Hwy 58 (Willamette Pass Resort) around to the southern ridge and up to the summit before descending and reversing course back to my car. 10.5 hours and 27.5 miles round trip. I wouldn't advice anyone to attempt to repeat this path as a day trip.

Mid-summer tromp in good weather  Sucess!

A nice half-day hike, but I can see how one might have an issue in poor visibility!

Nicer than I expected  Sucess!

As far as Oregon chosspiles go (and there are many of them), this is one of my favorites. With only a couple of hours' sleep at the rest area east of Oakridge, I arrived at the trailhead at dawn. The trail hiking went fast both ways. Rockpile Lake looked dried up (although I did not explore) but Marie Lake was gorgeous. I thought the off-trail approach was straightforward but I could see how novices might get off-track in the forest. Not as bad in that regard as the upper slopes of Mount McLoughlin, however. Once I reached the southern false summit, I really enjoyed the beauty of the mountain and its surrounding views. Don't believe the hype about the ridge "scrambling" as I only scrambled one time (and only because I wanted to), and all scrambling sections could be easily avoided. Heck, I saw prints from skateboarder shoes in the rocky sand, if that is any indication. It only took five hours roundtrip (three up, two down), giving me a comfortable time cushion for me to reach my next destination of the day: Yamsay Mountain. Yes, a Diamond/Yamsay road trip one-day slam. The things that crazy prominencians do.

good time of year to climb, very low snow pack  Sucess!

roads clear at any elevation. minor snow patches closer to marie and rockpile lake. most of the ground under snow near the lakes and the pct area. was able to stay on exposed ridgeline up the first half of the mtn but used crampons on the upper half. Some areas were soft enough to not need them. false summit to main summit had plenty of snow on the east side to cross and stay off of the rock but not too close to the edge. very few mosquitos still, but expect them to get bad soon. pioneer gulch might be a better route for the next couple of weeks if you're good with a gps, due to no trail visible up at the pct. (I used gps there too, it's tricky getting back to the lakes on the way down without it)

Little Snow Year  Sucess!

Came in from the Bear Mt. TH and hit the NW ridge to the summit. Snow level was about 6500! We were able to park at around 5500. Yes this is in February.

Beautiful Day  Sucess!

Great Peak. The last ridge was very scenic and view was amazing. Climbed by hiking to Marie Lake from Summit Lake and then heading north straight up the ridge. The only downer of the day is that the mosquito were horrible until we got half way up the mountain. I'd call this mostly a class 2 climb a few class 3 spots. High clearance vehicle needed for drive to Summit Lake coming in from the east.

Southwest Ridge-a blast!  Sucess!

Did this one with a friend from work. We left the Pioneer Gulch trailhead around 1030AM. Mosquitoes weren't too bad, but they were there. I bet in another week or two it would be nasty. We brought DEET and I would definitely recommend that.

It was an absolutely beautiful day with high temps in the 60s. Zero wind-I've almost never experienced a quieter environment. We reached the junction with the Corrigan Lake/Marie Lake trail and began the bushwack 40 degrees NE. As the route description on SP says, you can't really see that you're on the ridge until you're pretty high up on it due to trees and terrain.

We ran into snow around 6400 feet, but for a while it was optional--scree and talus on the ridge's high point or snow on the south side of the ridge. We decided to put the snowshoes on at some point and kept them on except for when we had to walk over some rockier sections. I wished I had brought crampons since the snowshoes I was using didn't have the best crampons and I had to use my ice axe a lot to avoid sliding down.

Summited at around 330PM. Found a guy and his dog on top. The guy was doing yo-yo ski runs down the east side and it looked like fun. He was the only other person we saw all day. Fantastic views of the Sisters and Thielsen, and Jefferson and Hood we're visible in the distance.

Although the hike back down isn't on a trail, we were often on our boot prints (even in the dirt) from earlier in the day because the route kind of naturally pushes you in a certain path. We glissaded on a lot of snow stretches and were making good time but got a little lost towards the bottom. Our senses of direction were telling us both that we needed to go right (North), but the gps was telling us we needed to go left (South). We should've listened to the gps because after a 30 minute detour we realized we were not where we should've been. It felt so wrong, we couldn't believe it. It's hard to get too lost because as long as you're heading downhill you'll run into a trail sooner or later (the Corrigan Lake/Marie Lake trail). The key is knowing which way to go once you hit it.

Anway, ice axe was a must. Snowshoes or crampons. I would've preferred crampons. At the time we went, the SW ridge would've still been ski-able in a lot of areas, but I don't know that it would've been worth hauling gear up for it. The east side was still very ski-able. A good 2-day shuttle trip might've been to climb up the SW ridge, then ski down the east side to the PCT, and then hike out from there. A good map is always a must, but in this case a gps would be useful for route finding. The gps app on my phone was actually more useful than the older etrex I had.

Summary, a long day, but nothing too difficult or technical. A lot of fun. Just make sure you know where you are, where you're going, and which way will take you back!

Snowshoe to the summit  Sucess!

Went with my cousin. Road 2160 still had snow so we hiked in from the intersection @ 2149. Hit continuous snow at about 5200' and used snowshoes from there on up.

Fun, airy, expansive views  Sucess!

Our party of 5 included a dog. Excellent hike and scramble, seldom visited. Little evidence of even a climbers' path. Loved it

Hot and Humid Hike  Sucess!

Drove FSR 6010 and 380 from the east. Hiked the Diamond Peak and Rockpile trails to Rockpile Lake, then on to Marie Lake. Bushwacked up the South Ridge route. It was a hot and humid day with intense mosquitoes near Marie Lake.

10 Aniversery  Sucess!

Proposed 10 years ago on top of Diamond, the return trip was just as nice. I love you Abby.
