The Idaho Twins


North Twin (10,196 ft)
South Twin (10,340 ft)


Wednesday, 21 September 2016
Route: Ascend North Twin from Twin Peaks Pass > Descend to Pass > Ascend South Twin > Descend to Pass
Distance: ~2.5 miles R/T
Gain: ~2200 feet


The Twin Peaks of central Idaho are two summits situated in the middle of the Salmon River Mountains, northwest of the town of Challis. From the valley around town, the peaks appear clearly visible and prominent. North Twin is the 5th highest peak in the range, while South Twin is the 2nd highest. The highest peak in the Salmon River Mountains is White Mountain. It stands at 10,442 feet, only 102 feet higher than its neighbor which happens to be South Twin.

Access to these peaks is incredibly easy. Challis Creek Road leaves town and becomes Twin Peaks Road (NF 086) as it heads northwest toward Twin Peaks Pass at 9,183 feet. The road to the top of the pass is very much what I'd call a "Subaru road," and from the top of the pass it is just over 1000 vertical feet to either peak. The pass forms the saddle between the two peaks and is a fantastic place to start a hike of one, both, or even a trio which would also include White Mountain. It's possible to drive all the way to the summit of South Twin where there is an old fire lookout, but that road is high-clearance 4x4 only, the fork for the road is a bit below the top of the pass, and why drive when you can hike?

With plans to hike peaks near Meadow Lake (southeast of Salmon) foiled due to rain--although the lake itself was very pretty--I was just driving around the middle of the state, and I noticed "Twin Peaks" shown on the map in my atlas. The marker was right off the highway near the town of Challis, so I did a quick google of the area. I found detailed Summitpost pages, and after learning about the easy access, decided to head that way and crossed my fingers for good weather.

I reached the top of the pass, got myself and Sven the pup ready, and set off for North Twin at 2:25 PM. The eastern side of the southwest ridge of North Twin featured a sort of cut in the forest, which I used to ascend the slope until I reached the ridge crest. From there, I made an ascending traverse just below a bump in the ridge and found another gap in the forest.

The second gap is covered in loose dirt and scree. It's not at a terrible angle, but enough to make upward progress somewhat of a task. After reaching treeline and returning to the ridge crest, I followed the ridge to the base of the false summit, where this time I encountered larger scree and small talus. I skirted the false summit through the talus and proceeded toward the real summit. After only 25 minutes of hiking from the pass, I was on the summit of North Twin at 2:50.

Rocky!

I spent a few minutes enjoying the summit and left at 2:55, following my ascent path down North Twin toward the pass. The dirt which I found tedious to ascend earlier in the second "forest gap" proved to be a wonderful descent path, offering premium scree skiing.

No choice but to scree ski, really.


I made my way down the first gap in the forest and reached the pass at 3:15, 20 minutes after leaving North Twin's summit. It looked like any possible rain was going to hold off for a while longer, so I made the decision to climb up South Twin as well. I crossed the road and was suddenly heading up again, this time along the northeast ridge of South Twin.

The second objective for the day.


From the hike of North Twin, this route looked steeper and more loose. It checked out. However, I also noticed what looked like a climber's trail heading up the ridge in switchbacks, starting about halfway up. I made it my goal to find that damn trail.

Loose stuff, part deux.


Progress up the ridge was slow, no matter where I tried to hike up. After passing remnants of previous mining-like development, I found the climber's trail and began to follow it. It was so much better than heading directly up the mountain!

Following the climber's trail now.


I followed the switchbacks of the climber's trail until I reached a rugged rock outcropping just below the summit. The talus slope steepened and became more loose as it reached the base of the outcropping. I carefully made my way up this section with Sven and was soon past it. I was under the impression that the entire route would be class 2, and I wouldn't be surprised if it can be kept that way on South Twin by somehow going around this outcropping, but I would say that this one tiny part of the route is class 3. It's fine without a helmet, but be aware you will most likely need your hands to help you get up this several feet of the ridge.

Once we were over the rock outcropping, it was a short stroll to the summit of South Twin, which we reached at 4:00 pm, making for an ascent time of 45 minutes.

I spent a bit longer on South Twin's summit, looking around and exploring the outside of the old fire lookout and other minor developments, as well as enjoying the views. From the summit of South Twin, a large chunk of Idaho can be seen, including the Sawtooth Range. Mountainous terrain dominated the view in all directions, and it was gorgeous.

At 4:10, I said my goodbyes to the summit and started down the ridge with Sven. We quickly negotiated the brief rocky outcropping and made our way down the climber's trail, eventually reaching the tedious lower half of the broad ridge. Before I knew it, we were back at Twin Peaks Pass at 4:35.

Having never been to Idaho (only through it a couple of times) prior to this little trip, I found this quick hike to be a good introduction to what the state has to offer in terms of peaks. The diverse colors of the Twin Peaks area only adds to the spectacular scenery. Headed to central Idaho any time soon? Check this place out; you won't regret it.
