A trip report and photos from Keith Wootton on the Greyhorse TH and trail.
Like your website, and love granite chief wilderness. Here is the latest on Greyhorse Creek. Rode motorcycle in, 10 miles of dirt road, no road markers and it is possible to take some wrong turns. Seven miles of the road have water bars about every 100 yards, and some trees and large rocks on road. Lots of rock up to baby head size, and the water bars are high, not something to take a car on. High clearance vehicle, bike, horse, or motorcycle are good. It took me about an hour to get to the trailhead, from French Meadows, which has a Granite Chief map but no other designation. Road beyond trailhead gets worse, and steeper, and I decided I really didn’t need to go to roads-end and another trailhead, although i could have made it, just slow going. Any other method of travel would take more time than motorcycle (i rode up from Foresthill).
Trail starts out faint for the first 100 yards, then runs into a sprawling mass of large uprooted trees that make the trail hard to follow, as you cross a melt water creek and push your way thru a willow thicket. Trees are recently blown over and all from the north, some have root balls 15 feet tall! I dont think there is any way a horse is going to make it thru. After that trail becomes much better as it switchbacks up between two meltwater creeks. About 2/3 way up hill, trail gets faint, then lost. Working up and to north towards bare rock outcrop with out crossing creek until you get close to rock will reward you with an easy to follow trail tread to the trail fork at the saddle. I continued north, and trail was easy to follow as it climbs, then drops down into Picayune Valley, though there were many more blown down trees. All with drying needles, and all from the north.
I gave up before reaching the valley, I got a late start, travel time was more than I thought, and it took some time to find my way thru all the down trees. I did do some exploring around, and think next time I will cross the saddle at the top of Greyhorse Valley, get a better look at the Johnson monument, and continue towards Mildred Peak and lakes.
