Basaltic lava flows are exposed in the valley across the center of this January 2021 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 61 km across). The valley is a tributary of Río Murta to the W. The flows were emplaced partly subglacially in glacial valleys cutting granitic rocks of the North Patagonian Batholith in the southern Andes. Lava flow features include columnar jointing, pillow lavas, and lava tubes.
