This peak is not found in the book.
Peak 9403 sits between Estes Mountain and Mount Greylock north of the Yankee Fork Town Site. It is 1.4 miles SSE of Estes Mountain, 0.8 miles NNE of Mount Greylock, and 0.6 miles east of Peak 9380. Climb this peak in conjunction with a climb of Mount Greylock.
Climb this peak from the saddle south of Estes Mountain. The summit is a 1.6 mile walk from the parking spot described below with an elevation gain that will vary depending on whether you cross over or skirt Peak 9366. Access to the ridge is set out below. Class 2. USGS Custer
The following access information expands on the access information in the book. Start on Loon Creek Summit Road [(F)(3.2) on Page 141], which begins just north of the Yankee Fork Dredge. From this road, you can access the ridge between Estes Mountain and Mount Greylock via a road that, as far as I know, does not have a Forest Service number designation. I will designate it as FS-3.2.2, Estes Mining Road. This road leaves Loon Creek Summit Road 5.1 miles north of the beginning of that road. The Forest Service map and the USGS quad show this road as a jeep trail but it is a well-maintained (albeit steep) road that leads up and over the ridge to the east. Turn right onto this road and drive 2.4 miles to the ridge top, where you will find parking and a spot to make a pleasant, dry car camp.
