I have not done this route and it looks very challenging with the elevation so be warned!!! I saved this as a future idea to check out. This goes from the summit of guanella pass to montezuma vai leavenworth creek, argentine pass , Red cone jeep trail, and Bruno Gulch trail this route is 67% dirt (gravel, 4x4 and single track) and 33% pavement (guanella pass rd)
