Director WENDY STURGESS Producer PAT HOULIHAN

The setting is the misty blue mountains of the Hindu Kush in northern Pakistan. Above towers snowcapped Mount Tirish Mir; below are the green and fertile valleys of the Kalash. The Kalash tribe have lived here for hundreds, perhaps thousands, of years; an independent culture and religion, a lost kingdom of their own surrounded by a sea of Islam. The women are unveiled and wear flowing brown robes decorated with cowrie shells. The men work in sparkling, flooded rice paddies terraced out of the hillside. Everywhere is the sound of mountain streams and the music of flutes.

In April last year, nine
KC 135 Stratotankers - flying petrol pumps - took off from Fairford to refuel the F-llls that bombed Libya.

The Wannabees
'I wanna be like Madonna'
TEN-YEAR-OLD GIRL
Never before have children been as heavily bombarded by media images of adulthood. But have children gone too far in their envy and emulation? Is there now a real risk of our children growing up too fast in a world increasingly dominated by expensive - and sometimes dangerous - fads and fashions?
Helen Boaden reports on Britain's image-conscious youngsters, and in the studio John Harrison discusses with parents, professionals and children the desires and anxieties surrounding 'the wannabees'.

Spirits of the Canyon
(Richard Wetherill 1858-1910) Presented by David Drew Richard Wetherill was a cowboy rancher in the American south west. In 1888, while searching for strays in the bleak canyons of the Mesa Verde, he and his brothers stumbled upon the extraordinary cliff dwellings of the ancient Indians - entire stone villages sheltered by giant rock overhangs, never before seen by white men.
For Richard, it was the start of a new career. From the wilderness areas of Utah to the plains of New Mexico, the heights of Colorado to the canyons of Arizona, the Wetherill wagons searched to find the lost culture of the Anasazi Indians.
But despite Richard's serious attempts as an archaeologist, he was accused by the Federal Government of pothunting and barred from further work. In the last programme of the series David Drew follows in Richard Wetherill 's footsteps and attempts to unravel the mystery that surrounds his death.
