Notes from Karst:
We made it up Mosquito Pass today. The stage was set before we even got to the hard dirt: a pickup truck along the side of the road with a front wheel that had fallen off. Score: one for Mosquito Pass. Benchmark Maps says that Mosquito Pass is the highest auto pass in the US.
We came up from the east and descended on the west side towards Leadville. The east side is definitely the more challenging side. I would call this side impassable for big bikes except for the most experienced riders. You will have your hands full even on a 650 dual sport bike. A smaller dirt bike will make things a bit easier. There were several sections that we walked to determine a route over the rocky steep sections for our dual sport 650s. Lots of big rocks, ruts and drop-offs on a steep road the last 3 miles. It probably is critical you ride with others on the east side to help you get your bike back up in a vertical orientation.
We came down the west side, but it sure looked easier that side for an ascent. There was only one hairpin that may be a bit challenging. Even then, lots of rocks on a steep road to contend with before you reach the summit.

The stone marker reads: J.L. "Father" Dyer. Methodist preacher, author, South Park missionary. Carried mail and gold over this pass - 1864. "The Snowshoe Itinerant".
