Image Caption:
Kulunda Steppe, Russia, eastern Kazakhstan. The vast plains
between the Irtysh (bottom left to center-top) and Ob' Rivers
(top right) are one of Asia's best landmarks because of the
great, parallel, dark lines of lower country occupied by lakes
(across the bottom and right of the view) (view to WNW). Exposed
in the west Siberian Plain, they are visible from great dis-
tances, and acted as a regular landmark in the vastness of Si-
beria for the STS45 crew who shot this dramatic Linhof view.
Here the Steppe is shown under snow: equivalent summer views are
requested. The NW-flowing Irtysh River is paralleled by a rail-
road. East-west railroads cross this axis at Omsk (arrow)--the
Trans-Siberian Line-- Pavlodar (P) and Semipalatinsk (S) both in
Kazakhstan (the latter lies on the west end of the largest arc in
the pattern of lakes). (S45-151-021)
