An adolescent Pashtun girl shields her face as she carries water through the streets of the Meira camp for earthquake survivors, Northwest Frontier Province, Pakistan. The conservative code of the Pashtun tribe of the area dictate that girls must cover themselves, including their faces, after their first period. The crowded life in the camp has made such rules difficult to follow. The Meira Tent camp (also called Mera, or Maria camp), is located on the Indus River in the Battagram district. The camp, the largest for displaced people in Pakistan, hosts over 21,000 earthquake survivors, primarily from the Allai valley in Pakistan's NWFP, one of the areas worst-hit by the October 8, 2005 earthquake.

A Pashtun man stands outside the Cuban hospital in the Meira camp for earthquake survivors, NWFP, Pakistan. The Cuban government sent 30,000 doctors, nurses and other personnel to set up field hospitals throughout the earthquake affected area.

A girl in the Meira tent camp for earthquake survivors stands on top of a pile of her family's belongings as they wait for transportation from the camp, where they have spent the winter, back to their devastated mountain village, in the NWFP, Pakistan. The Pakistani army, which runs the camp, has mandated that the camps be cleared by early April, despite the fact that many families are afraid or unprepared to return to their devastated homes.

Men from the village of Gangwal, which was devastated in the 2005 earthquake, show makeshift shelters that villagers constructed themselves after the quake, in the upper Allai Valley, NWFP, Pakistan. Most of the villagers fled to tent camps at lower elevations to spend the winter, leaving just a handful of families to look after livestock and possessions. The people of this remote area are Pashtun and until the earthquake, neither the government nor the military had much presence or influence in the region.

On the the road to the Allai Valley, men try to push a truck that is stuck in mud and landslide debris and which is blocking other trucks full of humanitarian aid and earthquake survivors returning to their mountain villages, Battagram District, Pakistan's Northwest Frontier Province. The region was one of the worst-hit by the October 2005 earthquake, and aftershocks and heavy rains continue to trigger landslides, which have hampered reconstruction efforts and the return of earthquake survivors to their mountain villages from the low altitude tent camps where many spent the winter.
