Ice-contact cliffs, more than 100 m high, on the east margin of Pali Dome, in the Mount Cayley volcanic field. Pali Dome consists of coarsely plagioclase-hypersthene± hornblende-phyric andesite flows. Proximal parts of flows have large diameter columns (up to 90 cm) overlying scoriaceous, oxidized, flow breccia, thus, appear to be subaerial in origin. Distal portions of flows, however, like the cliff shown below, are finely-jointed, with column diameters commonly less than 20 cm and columns arranged horizontally or in complex radiating masses; these flow margins were quenched against ice. These cliffs are flanked by more than 70 m of glassy debris.
