This thread is much appreciated. I will be touring across Colorado this June. Last year I toured Western Colorado for 4 days based out of Grand Junction. Since I was on my Royal Star, I could only get a glimpse of what lay beyond the asphalt, and hated to turn around when the asphalt ran out east of Silverton. This year I'll be on my brandie new KLR 650, and I have 10 glorious days, starting June 1st, to explore every dirt road in Colorado and Eastern Utah I can find. After slabing it from Indy to Colorado Springs, I am planning to ride Gold Camp Road to Cripple Creek, then Shelf Road to US 50. That's all I know at the moment. The other 9 days I am currently piecing together from information on this thread, as well as reading tons of Colorado Ride Reports on this site.
Thanks again for all the useful information!
