That's the Freezeout Ridge locality. I had been there many moons ago 
(yes from ed. 1 of Gem & Minerals Collectors'  Guide to Idaho). Some 
of the best huckleberry picking within a day trip of Moscow will be 
back up the road in the saddle in a couple months. The garnets are 
0.33 mi. S of the kyanite on the W side of the road. I went to the 
end of the road at Castle Rock and didn't do any better. The old camp 
past the lookout is a killer place to stay the night.
