Miñiques has two summits, a lower northern summit which reaches elevation and a higher southern one which is high. The mountain features two crater lakes, one at and the other at elevation on the southeastern and western side of the northern summit, respectively. A set of well developed moraines exists on the southern flank and may reflect glaciers advancing either from the summit area or a plateau at elevation; overall however glaciation on Miñiques was of limited extent and the terrain of Miñiques today is dominated by periglacial processes. Laguna Miñiques lies on its northwestern foot; it was separated from Laguna Miscanti by a lava flow from Miñiques.
