A day in the life of sky above one of the world's most remarkable escarpments. This one hour scene out of a seven-hour segment - noon to sunset - delivers a taste of life, just beneath the clouds of the Great Basin High Desert.

The stately growth, dissolution and movement of summer clouds range from blue sky to threatening storm.

The subtlety of the high altitude landscape is revealed by the changing pattern of cloud shadows and sunlight.

A sentinel Belding's ground squirrel periodically climbs up into a foreground sage for his own view of the day (and the camera crew).

Beneath the slowly transforming sky, the dominant experience is one of remoteness, purity and silence.
