The Pueyrredón/Cochrane Lake is a glacier fed lake located on the eastern edge of the southern Andes, straddling the border between Argentina and Chile. It is named after Lord Cochrane on the Chilean side and Pueyrredón on the Argentina side. The border is a peninsula the juts out into the lake on the North side. The border to the North of the lake follows the ridgeline of the last major expression of the eastern Andes.

A narrow land bridge separates the southern end of Lake Pueyrredon from the smaller, shallower Lake Posadas. Lake Ghio is the lake that is centered in the photograph. Asador Lake is in the upper-right part of the photograph. Lago Cochrane drains into the Rio Baker through the short Rio Cochrane on its western edge. Near the bottom right of the image is the glacier-covered Monte San Lorenzo. The 12,156 foot (3,706 meter) high Mount San Lorenzo has a small stream originating on its north flank that flows generally northeastward into Lake Pueyrredon. The vast semi-arid Patagonia Plateau covers most of the upper half of the image. The Ecker River and the Blanco River cut canyons across the plateau. The former is the main tributary of the Pinturas River.

The town of Cochrane and the Lago Cochrane National Reserve are located in the vicinity of the lake.
