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.

Great summit climb!  Sucess!

Climbed with Jason on a nice partly cloudy day, not too hot, reached the summit in 2 hr. 43 min. Total time was 5:37 including breaks, round trip. 9.2 miles according to Strava.

No go due to snow

Had a great day but no summit. The weather was crap, tons of fresh snow, low visibility, howling wind on the ridge, tons of rime ice on the trees. After 4 hrs to reach 8000ft, we turned back but still felt lots of satisfaction for braving the weather!

Brought The Rope  Sucess!

It was a great climb. Really everything you could want… a nice hike from the trailhead to the PCT; a fun and easy scramble above the trees from the PCT to the summit block; a short but serious scramble up the summit block. We didn't need the rope but it was nice to have it since a fall in the area around the summit would have been really terrible. Helmets are also nice… I hope to go back and do it again. Such an impressive looking spire. It really was the kind of climb that checks all the boxes.

I did go back again in the Fall of 2014 (see entry above) and climbed it again. The 100 days of good weather broke the morning of our climb and we had clouds and rain. Thielsen is a different mountain when the rock is wet. The thought of lightning up there is not one that will encourage you much either. Still, we made the summit a bit wet and with no hope of a decent photo. Just a selfie of ourselves in a cloud.

First cat to summit Thielsen?  Sucess!

Myself, my service dog, and Burma first attempted the peak on Jume 1st, 2013, but there was a lot more snow and ice than expected, and the peak repelled our attempt about 400 feet or so from the summit.
We returned in mid July after the snow had melted and Burma and I tagged the peak. Puppi waited below the 80 foot summit sphere.
We had a lot of fun! This climb is a must if you're in southern Oregon. :)
