It’s amazing how some peaks get all the attention, while lesser peaks get ignored. In 1992, I climbed peak 13,927, which is 0.5 miles W of Mt. Russell. That’s about a mile NNW from Mt. Whitney. The peak is now unofficially known as Mt. Morgenson, in honor of Ranger Randy Morgenson. The register (a tiny notepad inside a rusty Band-Aid can) had been lost for decades and then rediscovered. The second signature in the register was Norman Clyde in the early 1930’s. My signature was only the sixth one. While I was marveling at how rare it was for anyone to climb this almost 14,000 foot peak, I could see what looked like dozens of people milling around on the summit of Mt. Whitney. Mt Pickering and Mt. Young don’t see many ascents. You might be able to leave a wallet on either summit and find it a year later.
When I climbed Mt. Young, there was still a lot of snow. I went up the chute, not the switchbacks, to Trail Crest. The trails were pretty well covered in snow on the west side, so I just hiked cross-country. You might find a faint use trail on Young in the summer, but there is no official trail. You could follow the JMT to somewhere between Guitar Lake and Timberline Lake, and then head up sand and easy talus slopes to the summit of Mt. Young. Hiking from Trail Camp to Mt. Young and back would be a lot of work, but it wouldn’t require any special skills.
