As of 10/6/13 at 528pm, the CO Hwy 119 through Boulder Canyon has reopened. The most recent information is that OSMP and all the terrain north of CO 119 is closed.
The September floods released significant rockfall, and the Canyon is closed at the entrance out of Boulder. Certain areas may be accessible from Nederland, but it is unclear when the road will be reopened and whether pullouts for parking will be damaged.
This information is a public crowdsourcing effort between the Access Fund,
and Mountain Project. You should confirm closures, restrictions, and/or related dates.
Start on two underclings in the black part of the rock by the campfire. Throw first with your left to a microcrimp. Match here and keep moving left. Traverse as far as you want or top out (not recommended).
A pad would be nice depending on how high you're going. If you plan on topping this out it will be to the top of Castle Rock.
