I did "Windfall" a couple of years ago and it was cool! I did the first three pitches in 1 190' pitch, combining the 10a (a fun flake taking 3/4" gear), to 5.10 liebacking w/ 1 1/2" to 2" cams to the .11a fingers at the roof, which widens to thin hands over the lip. I went up & left on face to the ramp out left which leads to belay #3 on the old topo. The second pitch had a chimney w/ a chockstone then the business begins. Hand & fist in a bronze/orange corner and steep like the "Enema". Oh yeah, by the way, there's a mean 1 1/8" section to get to the ledge.
We didn't get to do the last pitch, the .10c thin hands but it looked great. A nice series of straight in cracks & flakes!
The other two routes there looked dirty &/or licheny and seemed to receive less trafic than Windfall, which would be highly traveled if it were as easy to get to as the Cookie or Reeds cliffs are.
It's about a 50 minute hike. I can't tell you more about the approach other than it was up a series of talus gullies but most of the time the tall trees obscured any views of the cliffs. Scope from the road carefully & go for it.
