This is the block that came off during the winter ...


Mostly shady except in the mornings. It is brand new and is just outside of Irvington, WI.
As of now, there is only top roping with two developed routes.
The rock is sand stone and is not up to par with Necedah's quality. It is not crumbly but it is one of the more dirtier climbing areas that I have ever been too. There is a bar at the beginning of the trail to the bluffs.
Approach the bluffs from the top and rap down from main anchors. After climb out and set up a top managed system for the rest of the group.
A super-must-do classic would be "The Captain" 5.11- finger crack to off width roof.

Getting There 

Take I-94 to Menomonie, WI. Go South on Hwy 25 out of town to Hwy D. Make a right and follow until you reach Irvington. Go past the one bar and turn left on 420th street. Follow until you reach a pull off on the left side underneath big power lines. Roughly 600 yards. Then park and follow trail to the big power line pole and go down the bluff to a rope anchor. Good luck The bluffs are public land owned by the WI DNR.

The Captain 5.11- 6c 22 VIII+ 22 E3 5c PG13  Wisconsin : 420th Bluff
There are two crux's in the route. The first one is when you get to the roof. The second one is trying to pull through the off width roof. Height helps.Follow the finger crack up to the roof then work your way in to the parallel finger cracks up to the ledge. Then work you way up the off width crack and over the roof to the anchors....[more]   Browse More Classics in Wisconsin

The rock at 420th is just too brittle to safely climb on. A few of us when developing the area cleaned out the cracks, which froze solid in the winter. The ice then expanded in the cracks to the point of breaking off a HUGE block. The block that fell off is seen in the beta photo, it is the right most block about 3/4 of the way up. Also I uploaded the beta photo with the block circled. This sparked a realization that this rock is too brittle (Eau Claire Sandstone) and for the sake of preserving it should NOT be climbed on.
