Great climb with my Dad and my friend Tavva. Excellent views on the most crystal blue sky day with great glisades down the mountain.
Mr. Idahosummits, and I attempted this peak in the Spring, but were unsuccessful due to the snow filled gully that would have required crampons and an ice axe. So we made it up to the saddle, and got a unique view of the Big Basin area. There is nothing really known about this peak, other than if you have hiked in the Hyndman Basin area, and noticed it sitting above the canyon. It is a very impressive peak from many different sides, and it has a nice pyramid like summit.
So, I had a day to kill on Labor Day weekend, so I went back to this peak, went up the same route that Dan and I had attempted earlier (which is all cross country through sage, aspen, and pine forests). Then, made it to the Saddle of Jacqueline and this peak. The gully that leads from the summit to the west ridge is mostly a steep 50 to 60 degree slope with cliffs around it's sides. This is a hard class 2 slog in scree, and I don't recommend going up this route. Instead, there is a noticable goat trail that splits the face of the mountains summit from the west ridge to the rocky north ridge. Walk the trail from the west to the north ridge, and then just climb up the solid rock on the north ridge. The North Ridge is mostly a class 2 with some class 3 thrown in at spots. But, it's mostly a short climb once you land the north ridge. After I made it to the summit, I took some time to enjoy the views of the triple crown, and Big Basin. I looked for a USGS Triangulation Marker, but couldn't find one. So, i'm guessing that might be part of the reason it's not marked as a named peak on any maps.
I decided to return down the scree slope of the west ridge. Overall, the scree chute was fine, yet loose, but I'd really recommend a climbing helmet in this area, because this chute could be a prime spot for rock fall. So, if you want to avoid that risk, then just return back on the North Ridge.
After obtaining the West Ridge, I then walked it around and back out the main drainage between Jacqueline and the Peak of the Unknown and started my descent back down to the East Fork Road.
I guess the Peak of the Unknown is now a little known.
