Gorgan Bay, Iran. (A) April 1982 (NASA photograph STS003-010-586). Taken five years after the 1977 lowstand, this southwestward view of the fault-controlled southeastern Caspian coast portrays a narrow inlet to Gorgan Bay with a squat promontory just north of the channel. Note the western limit of Gorgan Bay waters, as well as the position of the Iran-Turkmenistan shoreline extending northward from the inlet. (B) November 1995 (NASA photograph STS074-708-035). By 1995 bay waters had transgressed westward, parallel to the Elburz Mountains, increasing the area of the bay by roughly one-half; the spit that defines the northern bayshore is longer and narrower owing to the westward flooding (arrow). Waters also encroached upon the eastern shore, widening the channel into the bay and changing the shape of the promontory. A lagoon, with a narrow outer bar (arrow), now covers what had been beach.
