Monte San Valentin
Monte San Valentin, also known as Monte San Clemente, is the highest mountain in Chilean Patagonia and the highest mountain south of 40S outside Antarctica. It stands at the north end of the North Patagonian Icefield.
Monte San Valentin can be climbed from Lago Leones, to the south east, or from Laguna San Rafael, to the west. The ascent is long and is particularly subject to bad weather. The accident and fatality rate is high.
There is some confusion about the elevation. It was originally estimated at 3,876m by Nordenskjold in 1921 but later thought to be 4,058m. The latter is the most commonly quoted elevation and is quoted here. A French group that climbed the San Valentin in 1993 included two surveyors, who calculated an elevation of 4,08020 m by using a GPS. In 2001 a Chilean group measured 4,07040 m, also using GPS. SRTM data also supports an elevation in excess of 4,000 metres. But Chilean IGM mapping gives only 3,910 metres. ChIGM maps are usually accurate and reliable, but the summit is uniformly white, which may have created problems for the cartographers.
Laguna San Rafael National Park
Although Monte San Valentin is often referred to as the highest mountain in all of Patagonia, Argentine Patagonia is considered to extend northwards to include Neuquen Province, which includes Domuyo .
