Dasht-e Kâhou (Persian:دشت کاهو means Lettuce Plain; Kurdish: گیادورن means vegetation harvest) is a mountaintop plain above Taq-e Bostan Mount located in north of Kermanshah city in west of Iran.
The plain is surrounded by rocky outcrops and its floor consists of fine-grained sediments in bright red color (Terra rossa (soil)).
Archaeological excavations have shown that about forty thousand years ago, Neanderthal humans used natural outcrops of radiolarite or chert around this plain to make stone tools.
Water from snow melt and rain passes through karst channels under the plain into the mountain's calcareous system and comes out as the Taq-e Bostan spring.
According to experts, the construction of this station, in addition to severe damage to the prehistoric open-air site, will destroy the unique vegetation and contaminate the karst aquifer of Taq-e Bostan and Do-Ashkaft springs.
