Thought I'd share some FA ideas which I've worked on over the past 12 years. Some of them are well known and have been attempted, others less so. They may or may not be worth doing, someone should let us all know. I won't be getting to them anytime soon.
Winterish:
NF Direct Sperry: Line by Mark and Ade back in 2010, but the obvious line straight up the middle awaits.
WF Sloan: you all know this one.
EF Pugh: Hella approach, great looking ramp, looks kind of like the EF of Whitehorse.
NF Kent: 3 lines already, but at least two others to do. 1 day climb, reasonable approach, can see it from I-90!
NF Booker: big, awesome. Reported to be decent, if not abundant, ice by the folks who have been back in there.
Labor Day Route Shuksan: I've seen it filled in exactly once. Any route you want up to the summit pyramid, then the business.
WF Lincoln Peak: several big lines, some probably death routes, others look reasonable
NF Right Buck: NF Central was pretty rad back in 08, this one looks good too.
Summerish
NR of East Cashmere: 1 day c2c, one line on it already, but I think a better one awaits.
NEB-NR link-up West Craggy: Old Doorish route. Did an FA on this peak looking for the Doorish route, it was mostly poop, but the route to do is the NEB, which Doorish calls good, and then finish via the NR to the summit.
SEF Bears Breast: 2000' slab, could be 4th class like the route vaguely described in Beckey or there could be 5.10
NE Couloir Bonanza: May-June. I think this could be the safest route to the summit. Just around the corner from the NE Ridge.
SSE/SE Ridge Berge: Granite! Looks steep and not well-featured.
NR Cleator: Scary, big, nice line, good shot of it in CAG vol 2.
N Couloir McMillan Spires: May-June.
Chimney Rock Traverse: smaller version of a Pickets traverse, combine with Lemah for bonus.
WF Lemah: Pretty impressively shear when seen from Chikamin, rock is terrible, what else is new.
NER of University Peak, California, near Big Pine. 13000' beautiful granite with three N-facing soaring buttresses. Only line on it is a Beckey Route which predictably goes up loose gully between the buttresses.
