More switchbacks lead to Sentinel Pass where you should have no trouble finding a path beaten into the scree of the southwest ridge, just right of the pass. Churn your way up the scree. Below the first towering wall, traverse horizontally right on a path dotted with cairns and ascend the third gully to the right to overcome the black rock band. The first two gullies are much more demanding. Continue up more gravel-strewn black ledges, angling right to reach an easy spot to scramble up the next rock band, grey in colour.
Cairns are abundant and seem to multiply yearly.
Although the rock is generally firm, rubble on ledges and slabs requires caution. Handholds are plentiful and ascending this short band is pleasant. The rest of the way up the ridge is straightforward, but the terrain is still steep and rubble is precarious. Even without snow, an ice axe helps immensely. As you heave upward through the ever-thinning air, myriads of deep channels worn in the scree testify to the popularity of the peak.
