Left flank, South Side of the Dome. Left of Bishop Jaggers, left of the curving, right-facing corner of the main face, and just left of Stars of Mars (listed in the Hubbel book).
I can't believe this isn't listed! Great route at the grade, but old-school run-outs probably keep the numbers low. 2 pitches. I didn't recall the second pitch being much harder, but more run-out for sure as the angle drops off. (Feel free to add corrections.)
Left of Stars of Mars on the left flank/South Face; not as far over as the South Side crack routes.
I checked "sport", but WAY trad in the Platte tradition, in that there are relatively few bolts [read: you could get hurt]. A medium cam at the roof with a runner, 3 QDs, plus something for the anchors. I always use 2 ropes to rap; no clue whether a 70 meter rope could get you down.
