Mount Greylock

Elevation: 9,857 ft
Prominence: 1,037

This peak is found on page 131.


This shapely summit is just 43 feet shy of ten thousand feet. As I noted in the book it served as a fire lookout between 1934 and 1942. As you will see from the accompanying photos the lookout is no longer habitable. From the summit there are exceptional views of the Salmon River Mountains, the White Clouds and the Sawtooth Range.

Undoubtedly, a trail once led to the summit of this peak but you would be hard pressed to find much left of it today. The ridge line east of the Yankee Fork drainage contains many unnamed peaks that are worthy hiking goals. You will find wild country interspersed with old and new mining works. You may spot wildlife including elk, deer, mountain goats and wolves.

I climbed the peak in 2014 with Gilbert Gallegos and Andrew Chiles following the route suggested in the book which traverses the ridge between Estes Mountain and Greylock. We started at the saddle south of Estes Peak and followed the ridge south to the summit crossing two unnamed peaks (not in the book) on the way. The following access information updates the entry in  the book which is (F)(3.2) Loon Creek Summit 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 designated it as the Estes Mining Road. This road leaves (F)(3.2) 5.1 miles north of the beginning of the Loon Creek Summit Road. The Forest Service map and the USGS Quad show this road as a jeep trail but in fact 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. From the end of the road to the summit of Greylock it is roughly 2.2 miles depending on the line you chose. There are three unnamed peaks, Peak 9366, Peak 9381 and Peak 9403, that you can easily add to your itinerary. (I have added entries for each of theses peaks.)

We skirted the two intervening peaks on the walk over and then climbed over them on the way back. Here is our GPS track:

This may be the reason we only saw one goat. This wolf track was found nearby. Andrew Chiles Photo

The old lookout may not be habitable but it's still a good place to take a shady break and enjoy the view. Andrew Chiles Photo

There is a large open pit nine just to the west of the peak. It is a huge scar.
