In reply to myrddinmuse:
Southern route: Moab area (towers), Zion, Red Rocks, Needles, Yosemite. Or if the first three are too warm (north facing routes should be fine in Sept.), do Needles to Sierras alpine, to Yosemite.
“Direct” route: Notch Peak (by Delta, UT – multi-pitch lines on its N. Face look fantastic if adventurous), Lovers Leap, Yosemite.
Northern route: City Of Rocks in Idaho, Sawtooths (also ID, check out Elephants Perch), Lovers Leap, Yosemite.
Too bad Devils Tower is kind of out of the way as it probably is in the top 5 among unique N. American climbing venues.
