Ascend the scree field (lucky for us it was still snow) into Polemonium Bowl. Cross the terminal moraine of the Glacier, keeping to the right. You will see three peaks ringing the Bowl. To your left is Peak 13,962, ahead is Polemonium Peak, and to the right is Sill. The tops of Peak 13,962 and Polemonium are obvious; the top of Sill is not. Ascend the chute just past the moraine ridge; if your compass works, it will be on a Soutwest face. The lower portion of the chute is very loose small rock and sand, but not at all steep. Higher up, where it steepens, a ridge splits this chute and the right hand portion is firm rock. After reaching the summit ridge, traverse to the left to the summit. The only obstacle is a 10 foot notch that requires down and up climbing large blocks. However there is no exposure so even neophytes can handle it. On the descent the sandy (north) chute is the easiest.
