Analysis of satellite imagery of Google Earth has revealed the active, inactive and fossil rock glaciers, glaciers and areas with permafrost in Iran mountains. The total number of rock glaciers is 355–360, and 70 of them are active. The active and inactive forms occur mainly in the altitudinal range from 4400 to 2700 m. The fossil rock glaciers are sometimes recorded even at the altitude of 2450 m. The length of the largest fossil rock glaciers reaches 5 km. The length of the largest active and inactive rock glaciers ranges within 2.4 and 3.4 km. Small cirque glaciers predominate in the mountains of Iran. The largest debris-covered rock glacier reaches the length of 4 km, whereas their usual length is 200–300 m. The total number of glaciers does not exceed 30. They are confined to 5 mountain massifs. Permafrost is spread at least in the 30 mountain regions.
