Mt. Thielsen - Holly's Ridge Double  Sucess!

Mt. Thielsen and Holly's Ridge. Mt. Thielsen went as expected, easy few miles from the trailhead followed by scramble the last mile up to the summit. Good weather and great visibility.

Holly's Ridge was a difficult scramble from the PCT straight up to the saddle. 1K feet elevation gain on loose pumice with the occasional 4' snow drift. Tough going even for someone in good shape. After the saddle it's an easy walk across to the higher East summit which rewards you of amazing views of the northeast face of Mt. Thielsen including the Lathrop Glacier. 16.5 miles round trip with 5k feet of climbing. See the Vlog to see more.

Original entry  Sucess!

Not sure why this entry disappeared. Getting tired of finding my entries have vanished.

First climb was solo. Loved it.

Fun, easy trip  Sucess!

Fun overnight trip with two buddies. Hiked/splitboarded in and then camped on the ridge at 7300 feet and left for the summit at 5 AM the next morning. Took the left gully which was holding quite a bit of snow as opposed to standard switchbacks above the talus. Fun angled traverse of the gully, maybe 35 degree maximum in tennis shoes and ice axe. scramble above that to regain the regular trail was on very poor rock. Took a small trad rack for the summit pitch but easily a low fifth class solo. Fun outing!

Awesome summit  Sucess!

This was the most awesome summit. What a hike and climb! If you like a good scramble, Mt. Thielsen is for you! But be careful! The summit block is great rock with lots of hand and foot holds.

fun day on the mountain  Sucess!

Great day for a climb, I put together the climb on my meetup group. NW Wilderness. Had 8 people show up on a friday night drive for a Saturday Climb. out of 10 we had 9 summit, I being out of climbing shape stopped at about 8000 feet. No worries though it was my 4th trip up, I summitted all the others. This is my favorite climb in Oregon just always a fun one and so scenic. Doing 3fj in a few weeks. The most exposed mountain I believe.

Fun scramble  Sucess!

A fun morning scramble to break up the commute through Oregon. The summit knob is 4th class and remarkably solid. Trip report.

37 peaks in 19 days  Sucess!

There was bad weather for weeks in WA so Heather and I drove through OR, CA, NV, UT, and ID. We climbed 37 peaks in 19 days and Thielsen was the first. It was not as cool as all the hype I've heard over the years. In fact, the approach was rather boring. We did not use a rope. trip report

West Ridge Beautiful Day  Sucess!

Some smoke to the South, but otherwise very clear. Nice fast hike with Todd. Quite a few other parties.

Enjoyable, even with the smoke  Sucess!

Lots of smoke from the fires Northwest of Crater Lake. Met a father and his 12 year old son at the summit pinnacle rapping down, bravo for him giving his son a great outing. Enjoyed the brief scrambling on the summit pinnacle, only wished for better views.

Blue Sky Day  Sucess!

With Sue, Mark (birthday boy) and Natasha. Went up with axes and crampons but never even needed to put on gaiters. Sunny day, fun pinnacle climb and good Mexican food in Roseburg on the way home.

Roadtrip  Sucess!

Drove from Portland to Mccredie hotsprings, then Crater Lake, camped at Diamond lake then climbed Theilsen the next day. Snowy conditions, lost the trail a few times but made it all the way. Thrilling scramble to the top and amazing views. Perfect temperature and weather all day. Only saw one other couple the whole day.

Pleasant Surprise  Sucess!

Climbed on a whim while visiting a friend working at Crater Lake. Sloppy snow but we had a blast.

Awesome!!  Sucess!

Amazing climb! There were a couple of big rocks that came tumbling down during the scramble to the spire that made me wish I had my helmet, but otherwise a great day.

West Ridge  Sucess!

Team of three. Climbed this one on our way up to Smith Rocks. It has a fun finish and great views from the top.

Clouds & Rain  Sucess!

We summited but it was wet and cloudy the whole way. The summit block was wet and I would have never done it without some slings, a rope and a cam halfway up the pitch. It is "only" 80 feet but people who say everyone can just scramble it are totally irresponsible. It is certainly doable but if you did take a fall, it would be your last.

Solo climb  Sucess!

Seems like this mountain is a favorite for people to solo! I did it as well on a drive from California to Oregon. The route finding was pretty straightforward, and I was armed with some friends' beta, that the right side of the summit pinnacle was easier than ascending the left side. I'm a weenie on exposed third and fourth class, and this was just the right amount of exposure to scare me, but that I could work through. Great sense of accomplishment without an insane amount of difficulty. I'm a relatively slow and steady hiker, and this took me 6 hours and 20 minutes.

Perfect Exposure Level  Sucess!

Loved this hike. Just enough exposure throughout the second half to keep you on your toes and keep your heart pumping, but it's never anything over the top. One of my favorites in the area now, right up there with McLoughlin.

Solo day  Sucess!

A fantastic visit with spectacular views even with the forest fire smoke in the distance. Views reminded me that I need to climb Baily, Diamond, Mt Scott and many other unknown to me mountain features in this area.

Fairly easy walk to the PCT and summit trail junction.

Quite a few other climbers.

Classic and short volcanic scramble to the "chicken ledge" below the spire.

Climbed the N-NW side of the spire to the summit with fantastic exposure and a 2000+ drop to the glacier below. Got the heart pumping. Gusting wind made me wonder if climbing without a rope is such a good idea for such a climber as myself. After inspecting the spire from other angles- I would like to return with rope to play on a few other places. Climbing the spire from the "Chicken Ledge and staying a bit more to the center or even slightly more to the south seems a bit easier.

Lots of neat stuff to hike about and climb upon in the summit area.

Fantastic geology and photographic subjects.

Good conversation with PCT through hikers.

I will be back with my Wife and or Grand Kids for this one.
