Short notice but the weather looks good for this kind of ride. Think of this as a warm up (11,600 foot) for the to-be-organized Nivot Ridge ride. Jenny Creek starts at the Eldora ski resort and winds its way up along rocky and sometimes wet trails past Yankee Doodle Lake all the way to the continental divide. The views up there are spectacular but the air is thin and perhaps even cold. This is a bit of an adventure ride: it takes some time to get up there; you could get a little wet; there are intriguing but hard to find options, e.g., the connection from Jenny Creek to the Guinn Hut trail (sweet but short single track).
