#10 Colorado Trails Vol. I Video: Volume I of the Colorado Trails begins at the London Mine in Mosquito Pass and then shows Holy Cross City (near Red Cliff), Battlement Mesa (near Alma). The video finishes with a rollover on the Mine Sweeper Trail, a set of granite steps that will challenge even the best drivers and their vehicles. All the trails were run in June when the snow and mud increased the difficulty rating on higher elevation trails. There are 12-15 vehicles on each trail including CJs, YJs, TJs, Broncos, Toyotas and full size trucks. If you like 4-wheeling in the snow and mud, you’ll enjoy every minute of this video. 1997. Running time approximately 82 minutes.
