A hulk of a peak, this tower has a broad summit area with lower angled slabs at the top; its adjoining spire, Bollard, is at its base, and is one of a number of wide buttresses / pillars that have their accompanying deep chimney counterpart; these thin out higher up the formation. Spinnaker's north face has some formidable lines; its east side is also quite featured and shares its col with the basalt ridge line, which rims the Black Bowl, leads north, then west, & ends with the spire across the Black Gully from Spinnaker: Crow.
