Chimborazo, Pico Nicolás Martínez. Of the four peaks of Chimborazo, its lowest (c. 5570 meters, 18,275 feet) is the most attractive and most difficult. It was named “Nicolás Martínez” after a great Ecuadorian pioneer of the early 1900s. In 1983, two new routes were made on its flanks: O. Morales and M. Purúncajas climbed the southeast glacier or “Glaciar Boussingault” (June 26). The second new route was made by J. Anhalzer, R. Cárdenas and R. Navarrete, following the northeast ridge (July 3).
