阅读理解所给的答案中Samarkand的方位是在mountains and the airport之间，但它所说的依据局句并没有提到mountains，所以想问下Samarkand的方位是如何判定的？

文章的第一段：

    I myself first saw Samarkand from a rise across a wilderness of crumbling ruins and great graveyards which lie between it and the airport. Suddenly we caught a glimpse of painted towers and the great blue domes of mosques and tombs shouldering the full weight of the sky among bright green trees and gardens. Beyond the gardens and the glittering domes still were those watchful mountains and their evocative snow. I found myself thinking of the thrill I had on catching my first sight of Damascus after crossing the desert from Syria. The light, file orchards and many of the trees were the same but deeper still was the sense of coming into contact with one of the most astonishing cultures in history, the world of the one and only Allah and his prophet Muhammad. It was a world that completely overawed me.
