Vashi Canyon

Tangeh-ye Vashi (Persian: تنگه واشی) (35°52′33″N 52°43′37″E) is a gorge and mountain pass in the Alborz mountain range, Iran. The narrow gorge was created by a perennial stream which comes down from a series of waterfalls upstream. Slightly lower, in a hilly area, the stream provided a patch of grazing land within the mountains.
