Grand Coulee is a large coulee on the Columbia River Plateau.This area has underlying granite bedrock, formed deep in the Earth's crust 40 to 60 million years ago. The land periodically uplifted and subsided over millions of years giving rise to some small mountains and, eventually, an inland sea.
Moses Coulee is the second-largest and westernmost canyon of the Channeled Scablands, located about 30 kilometres (19 mi) to the west of the larger Grand Coulee. This water channel is now dry, but during glacial periods, large outburst floods with discharges greater than 600,000 m 3 /s (21,000,000 cu ft/s) carved the channel. [ 1 ]
The Channeled Scablands are a relatively barren and soil-free region of interconnected relict and dry flood channels, coulees and cataracts eroded into Palouse loess and the typically flat-lying basalt flows that remain after cataclysmic floods within the southeastern part of Washington state.
Coulées (or coulees) are lava domes that have experienced some flow away from their original position, thus resembling both lava domes and lava flows. [ 2 ] The world's largest known dacite flow is the Chao dacite dome complex , a huge coulée flow-dome between two volcanoes in northern Chile .
The Etzikom Coulee begins northeast of the town of Stirling, and makes its way southeast of the Hamlet of Wrentham, after that it passes by the Hamlet of Skiff into the Crow Indian Lake, then southeast of the Village of Foremost as well as the Hamlet of Nemiskam, and finally ending south of the Hamlet of Etzikom at Pakowki Lake, the largest lake in Southern Alberta.
