Lake Hövsgol Rift & Transform Fault: Lake Hövsgol, north-central Mongolia, occupies a rift valley (graben) that is linked with the Baykal rift system, 200 km farther east in the southeastern Russian Federation. This exceptional view shows not only Hövsgol but also another rift valley to the west, which is of similar size but lacks a lake; the eastern and western margins of both are normal faults that drop the valley floors down. A straight, east-trending transform fault zone bounds the valleys on the north; this transform zone extends eastward, linking the Hövsgol complex with the great Baykal rift. Structural details of this remote and seldom-imaged region are now being mapped for publication by Office of Earth Sciences staff and Russian colleagues in Irkutsk.
