The mountain 
Popocatépetl  (5,426 m (17,802 ft) is an active volcano, located in the states of Puebla, Mexico, and Morelos, in Central Mexico, and lies in the eastern half of the Trans-Mexican volcanic belt.  The name Popocatépetl comes from the Nahuatl words popōca  (it smokes) and tepētl  (mountain), meaning Smoking Mountain. It is the second highest peak in Mexico, after Citlaltépetl (Pico de Orizaba) at 5,636 m (18,491 ft).
It is linked to the Iztaccihuatl volcano to the north by the high saddle known as the Paso de Cortés.
Popocatépetl is 70 km (43 mi) southeast of Mexico City, from where it can be seen regularly, depending on atmospheric conditions. Until recently, the volcano was one of three tall peaks in Mexico to contain glaciers,[6] the others being Iztaccihuatl and Pico de Orizaba. In the 1990s, the glaciers such as Glaciar Norte (North Glacier) greatly decreased in size, partly due to warmer temperatures but largely due to increased volcanic activity] By early 2001, Popocatépetl's glaciers were gone; ice remained on the volcano, but no longer displayed the characteristic features of glaciers such as crevasses.
Magma erupting from Popocatépetl has historically been predominantly andesitic, but it has also erupted large volumes of dacite. Magma produced in the current cycle of activity tends to be a mixture of the two.
Climbing route 
The first ascent was made by ameridian Tecuanipas in 1289. Nowadays the easiest way to reach the top is via the north face. It begins at Tlamacas Lodge located at 3947 meters above sea level and accessible from the neck separating the Popocatepetl of Ixtaccihuatl via a paved road. The trail, which passes through Las Cruces and crosses snowfields and glaciers, measuring nearly five kilometers long with a climb of 1453 mètres. The best time to climb is winter and early spring, especially from  December to  April. The first mountain ski descent was conducted by Francisco Gonzalez Rul and Eduardo de Maria y Campos 1947.

The photographer 
 Alfred George Buckham  was a British photographer who specialised in aerial photography. He began his career in photography in 1905 and joined the Royal Naval Air Service as a reconnaissance photographer in 1917. He became the first head of aerial reconnaissance for the Royal Navy in the First World War and later a captain in the Royal Naval Air Service. Buckham was involved in 9 crashes, 8 of which saw him relatively unscathed. After the ninth, however, he had to have a tracheotomy and breathed through a small pipe in his neck for the rest of his life. Despite this, he carried on his aerial photography career, often in very perilous conditions. He felt the best shots were made standing up, writing If one's right leg is tied to the seat with a scarf or a piece of rope, it is possible to work in perfect security.
