Thanks Moogie. I'll update that page. I see you went up Kays Creek. Gotta love those switchbacks huh? Thats why Adams is the better of the two. But, you made it, and thats what counts. If you want a very direct route, check out the Layton Peak page, and the Community Trail route. That is steep, and Layton Peak is just north of Thurston. You passed just below the summit I'm sure.
This might be well known, but about 1/3 of mile north of the ridge there is a natural spring on the Great Western trail. If you find yourself up around Thurston on, say, a July day and you're low on water, this might be helpful.
