Pico de Orizaba

A 5,636-metre stratovolcano in central Mexico, the highest peak in the country and the third-highest in North America after Denali and Mount Logan. Pico de Orizaba — also known by its Nahuatl name Citlaltépetl, "star mountain" — sits on the border between the states of Veracruz and Puebla. The volcano is currently dormant, with the most recent confirmed eruption in 1846, though geological monitoring indicates the peak remains capable of significant activity. The summit holds permanent glaciation, the southernmost glaciers in North America.

The first recorded ascent came in 1848 by an American expedition led by William Reynolds. The team reached the summit on May 5, 1848 — during the Mexican-American War — and the political circumstances of the climb produced extended diplomatic and scholarly debate about whether the expedition counted as the first ascent. The climb was repeated by various Mexican and international expeditions through the late 19th century, and the mountain became one of the early Mexican mountaineering destinations.

The standard route is the Northern Glacier route from the Piedra Grande hut at 4,260 metres. The climb takes a single long day from the hut, with most parties starting at 1 a.m. to reach the summit before the daily warming destabilizes the glacier. The route involves a long approach across volcanic scree, the transition to glacial ice at approximately 5,000 metres, sustained climbing on a 35-degree glacier, and a final summit dome with crevasse routing that has changed substantially as the glacier has retreated. The Jamapa Glacier, which the route ascends, has lost approximately 80 percent of its mass since the 1980s.

Orizaba is climbed by approximately 1,000 summit attempts per year. The fatality rate is moderate, with most accidents involving altitude sickness on the rapid acclimatization profile that the standard climb requires. For climbers progressing toward larger objectives, Orizaba has functioned as a primary North American 5000-metre peak, comparable in role to Cotopaxi in Ecuador or Huayna Potosí in Bolivia. The summit views, on a clear morning, extend from the Gulf of Mexico to the Pacific.
