"Those are the obo, the sacred signs and altars for the bad demons watching this pass," explained the guide. "This pass is called Jagisstai. Many very old tales about it have been kept alive, ancient as these mountains themselves."

We encouraged him to tell us some of them.

The Mongol, rocking on his camel and looking carefully all around him, began his tale.

"It was long ago, very long ago. . . . The grandson of the great Jenghiz Khan sat on the throne of China and ruled all Asia.
