Devils Lake TH  Sucess!

I pulled in to the Devils Lake TH parking lot around 2 a.m. At that point the lot was about 2/3 full. By the time I was up and walking at 8:30 a.m., the lot was overflowing and vehicles were parked up and down the highway.

At 6900' I encountered 3 state police officers who were part of a larger group running SAR drills. I stopped and talked to them for a good 20-30 minutes. Once I was on my way again, I met 10-15 other officers who had been participating in the drills on their way down.

Once at 9000', I began to encounter the masses -- both ascending and descending -- all of whom had clearly gotten an earlier start than me. It was pretty busy for a Thursday. I cannot imagine how full this trail gets on the weekends. Part of this is accounted for by the straightforward and easy-to-follow trail as well as the nontechnical demands; South Sister may be more fun and certainly less crowded in the snow.

I took the entirety of the crater ridgeline counterclockwise. There is an abundance of top-notch bivy spots if you are so inclined to spend the night up there. I was at the summit by noon and spent a solid hour before heading back down. The views were spectacular: Middle & North Sister, as well as Three-Fingered Jack, Jefferson, Hood, and Adams were all clearly identifiable.

With an uneventful descent, I was back at the car by 4.

Long day with high rewards. Great views north and south along the Cascade range.

Felt like I was carrying rocks  Sucess!

Beautiful outing, classic view but a pathetic effort. Had no energy at all, took over 5 hours to summit. Was warned about terrible mosquitos but they were only in the trees and not even that bad. Gorgeous, gorgeous, gorgeous!

Enjoyable scenic hike  Sucess!

A very dramatic mountain with a range of landscapes on the way, interesting summit crater, and great views all around.

You're not an Oregonian unless you've done South Sister!  Sucess!

My 5th or 6th South Sister climb. I used to do it every year, but I grew tired of the crowds. It's not bad if you can get an extremely early start.

Some of the best summit views in Oregon.

First Oregon Volcano

Via South Ridge  Sucess!

A beautiful day. Route is pretty much snow free. No need for spikes or an axe. Just some poles are helpful. Watch out for mosquitoes below treeline in the morning and at night, they will eat you alive. The route gets very hot around noon and throughout the afternoon so I would suggest an early start.

Nice scrambling  Sucess!

About two and a half years later, I would find this climb qualified me for the membership of Mazamas (

Goal achieved  Sucess!

This peak had been on my mind for years, and despite being out of shape, I made it... along with many, many others. I was fairly surprised to see that Teardrop Pool had not yet formed yet for the season... and that wildfire smoke from 150 miles away permeated the air.

Beautiful day clouded over  Sucess!

A very difficult hike but we reached the summit in 5 hours and descended in 3.5 hours with a group of 11 at a variety of skills and fitness levels. We started at 7:45 am, glad we didn't start any later because the storm rolled in once we reached the peak.

Gloves and trekking poles were a must, micro spikes were very nice to have.

We had great weather until right before we reached the summit - then it clouded over and snowed the whole way down. Be prepared for all weather, even on a clear sunny day, it can change very quickly!!!

Run up  Sucess!

Summited with a buddy, running much (but certainly not all) of it, beautiful day, during a nice break in the summer smoke. Lots of fun rock jumping and sliding through the scree on the run down. 3.5 hrs, with lots of stops for pics. Fun summit, epic views.

Climb and ski  Sucess!

Great climb and descent! Left at 6 from Devils Lake. Still snow from large boulder about a mile from the trail head until the crater and actually stayed in the crater on snow most of the way along the ridge. Basically a boot pack the whole way. Skied down from just below the summit all the way back to the boulder. Took skis off just a couple times for small portages. Took our time. Back to the car at 3.

Heavy Cloud and Wind  Sucess!

South Spur to the top. Real windy and chilly up there. Traveling fast and light feels great, but didn't allow us to any time to enjoy ourselves up there. Not that there was anything to see.
