After clearing it with my physical therapist, I decided to test my left shoulder on a moderate hike to Cienaga Peak. The MRI and surgery are still weeks in the future. Most of the pack weight was carried by my hips, while the shoulder straps were supported mainly by the collarbone and trap muscles. Nothing directly hit the external rotator or deltoid. I modified how I put the pack on and took it off, and didn't use my left arm with the hiking pole. I tried to keep the left arm down and stationary.

I arrived at Humber Park in Idyllwild about 8:45 AM to a mostly empty parking lot. It was sunny and cool, 55F, where pleasant temps hovered all day. I think the San Jacinto Wilderness is the most beautiful of the three major SoCal ranges (others being the Angeles and San Bernardino). I had kept this peak in my back pocket for when I needed a chill hike. I really needed a chill hike. I started up the Devil's Slide trail, a moderate grade with soft sand winding through giant evergreens. I was focused on my shoulder as I gained elevation. At Saddle Junction, everything seemed OK. I turned north on the PCT and hiked to the saddle north of Cienaga, then came back south to the summit. When I left the PCT, I had about a quarter mile of open country to reach the summit. I half expected a use trail, but found none. I went around various boulder piles until I reached the highest one. Since Cienaga has low prominence, I didn't see the summit through the trees until I was near. The summit block was about 20', class 2. I dropped my pack and was able to get up without using my left arm at all. Cienaga was not a listed peak, but there was a register in a single can. The most recent visit was a week prior and it appeared quite popular based on the number of entries. The views were great up toward San Jacinto and the satellite 10k peaks, and down to Tahquitz Peak and Suicide Rock.

A note on permits: The Devil's Slide trail starts in a national forest and requires a self signed day use permit you can get at the Idyllwild ranger station. The section of the PCT that heads toward San Jacinto goes through the state wilderness and requires a different day use permit. The route I followed barely crosses into the state park (about 500') before turning south. Cienaga itself is in the national park. I didn't have a state wilderness permit, but if you left the trail earlier, it wouldn't even be a consideration.

My shoulder seemed no worse the day after, no noticeable change in pain. This was a successful test of the shoulder on a moderate hike, and I'll take it. I'm slightly encouraged, but I'm not counting it as a data point for how things will feel post recovery.

Mount San Antonio routes

This is a meta post showing the most common official and unofficial trails to Mount San Antonio (Mount Baldy).


The official trails:
  • Ski Hut trail (aka Baldy Bowl trail)
  • Devil's Backbone
  • North Backbone
  • Bear Canyon
The unofficial trails:
  • Register Ridge
  • San Antonio Ridge
Here is my take on difficulty in ascending order:
  • Devil's Backbone
  • Ski Hut trail
  • Register Ridge
  • North Backbone
  • Bear Canyon
  • San Antonio Ridge

The Devil's Backbone and Ski Hut are the most popular by far. If you want solitude, any of the other trails get you some.

The single ascent I did in winter was the Ski Hut trail, and it was quite a bit more challenging with snow and ice. The Devil's Backbone is notoriously dangerous and fatal when covered in snow.

Register Ridge used to be a faint use trail, but it's well groomed now and seems more like a maintained trail.

For the San Antonio Ridge, I went up the Ski Hut trail, then descended from Mount San Antonio to Iron Mountain #1 and finished at Heaton Flat. The trail along the ridge is good until you get to Gunsight Notch, then it becomes technical and harder to follow. It remains one of the most difficult and dangerous hikes I've done.

An uncertain future

A couple of weeks ago, I started getting severe pain in my left shoulder. It built up over four days, and I woke up one day with limited ranged of motion. Multiple trips to the doctor, including a PT and orthopedic, showed arthritis and deterioration of the joint. The orthopedic recommended a shoulder replacement and I am waiting to complete the MRI and CT before scheduling the surgery. It will be a very long and difficult recovery with some permanent loss of strength. It's unknown whether I will be able to get back to the challenging scramble routes I enjoy the most. I knew the day would eventually come, just not this soon. I am left with mixed feelings about whether to continue my peak bagging adventures or call it.
