Guido Tamayo
Guido Tamayo was a pioneering Colombian mountaineer and explorer who co-achieved the historic maiden first ascent of Ritacuba Blanco (5,410 m) alongside Erwin Kraus on April 3, 1942. His relentless exploration of the Sierra Nevada del Cocuy helped establish domestic mountaineering across the Cordillera Oriental of Colombia.

Biographical Record & Archival Chronicle
Guido Tamayo was one of the core pioneers of twentieth-century Colombian alpinism. Possessing exceptional physical endurance and a passion for high wilderness, Tamayo joined Erwin Kraus during the golden age of Colombian mountain exploration in the early 1940s. At the time, the glaciated peaks of the Sierra Nevada del Cocuy in the department of Boyacá were known only from distant paramo trails and indigenous legends.
In March 1942, Tamayo, Kraus, and Heriberto Degen organized an expedition into the northern heart of El Cocuy to attempt the highest peak in the Eastern Cordillera: the unclimbed ice dome of Ritacuba Blanco (5,410 m). Overcoming freezing rains, steep moraines, and the thin air of the paramo, the three climbers established an assault camp beneath the western ice tongue.
On April 3, 1942, roped together across untracked glacial firn, Tamayo and Kraus climbed steep 45-degree snow slopes, skirted crevasse chasms, and navigated an exposed corniced arête to step onto the 5,410-metre summit. Tamayo's success proved that native Colombian climbers possessed the technical courage and stamina to conquer their country's highest ice walls. Tamayo continued to explore El Cocuy for years, helping map high-altitude passes and inspiring the establishment of Colombia's earliest mountaineering clubs.

Ritacuba Blanco
Ritacuba Blanco is the 5,410-metre crowning peak of the Cordillera Oriental of Colombia and the Sierra Nevada del Cocuy. Dominated by a massive western ice sheet and sheer eastern rock walls dropping precipitously toward the Amazonian llanos, Ritacuba Blanco is celebrated for its pristine glaciated ramps and high-altitude paramo lakes. The mountain was first climbed on April 3, 1942, by Erwin Kraus, Guido Tamayo, and Heriberto Degen.

Ritacuba Blanco Normal Route (West Glacier)
The classic ascent of Ritacuba Blanco ascends the expansive western glacier sheet of El Cocuy from the Kanwara cabins. Featuring steady 35°-45° snow slopes, crossing moderate crevasse bridges, the route tops out on an airy corniced summit knife-edge overlooking a sheer 1,000-metre drop into the eastern llanos.
