Trachytic pumice cones drape the upper NE flanks of Paka volcano in this view from the NW. The dark-colored trachytic lava flow with visible flow ridges at the lower right traveled down the N flank through a breach in the caldera wall. The 1.5-km-wide summit caldera is visible to the upper right, and a large crater to the SE appears to its left. Areas with brown vegetation are geothermally active.
