It lies west of Mount Fitz Roy, east of Cerro Rincón, and in the northern part of the Circo de los Altares. It stands at an altitude of {{convert|2465|m|abbr=on}}.

On the Chilean side, it is part of the Bernardo O'Higgins National Park, while its eastern side lies within the Chaltén Mountain Range Natural Site, which is part of the park.

Chile previously claimed the entirety of the mountain. However, following the arbitration ruling in the Laguna del Desierto dispute in 1994, the boundary was set on the mountain, recognizing it as a binational landmark by both countries.{{cite web|title=Cerro Domo Blanco, Chile/Argentina|url=https://www.peakbagger.com/peak.aspx?pid=28931|publisher=Peakbagger|accessdate=October 29, 2024}}{{cite web|title=The Laguna del Desierto case|url=https://jusmundi.com/en/document/decision/en-boundary-dispute-between-argentina-and-chile-concerning-the-frontier-line-between-boundary-post-62-and-mount-fitzroy-decision-friday-21st-october-1994|publisher=Jusmundi|accessdate=February 2, 2023|language=en}}{{cite web|title=Boundary dispute between Argentina and Chile concerning the frontier line between boundary post 62 and Mount Fitzroy|url=https://legal.un.org/riaa/cases/vol_XXII/3-149.pdf|publisher=Legal UN|accessdate=February 2, 2023|date=October 21, 1994|language=en}}
