Saw Brian's WY 5th class peaks here. Interesting set of summits.
Most of these peaks are listed as 5th class in the Turiano and Kelsey guidebooks. Which is how they got rated as such on this site.
Additional info from my notes.
More definite 5th class for WY:
Coffman Butte
Boedecker Butte
Inominate - 5.10, final boulder
Mt Woolsey
Black Rock - 5.2, see report
The following I have seen in person from various angles/distances and are possibly/likely technical:
Cathedral Spire 5th class route done in 00s
10725
10683
10983
10340
11098
10912
12026(S)
11140
11690
Bear Head Mtn
South Chimney FA in 90s
Camel Rock
12590
8180
I've heard Black Tooth has a 3-4 route somewhere on the S side.
The above are limited to what I've actually seen in person. Just going off maps and steepness figures, there are many other possiblities.
