For some reason, the Mount Bierstadt page is attached as a child to this route page:
Two messages by two users have been sent to the owner of the route page to no avail. Perhaps you can detach Mount Bierstadt as a child to the West Slope Variation?
I reattached the route page as a child. Thanks for the heads up.
Guanella Pass is currently closed indefinitely due to a rock slide on the north side of the pass. Access to the Guanella Pass Trailhead is now possible only from the south from Rt 285. Source.
Winter access: Guanella Pass Road is no longer plowed to the pass in winter. The winter access trailhead is 1.5 miles south of the pass.
