MIDWEST REFINING - 1921

On June 17, 1921, it set ablaze the Midwest Refining Co. tank farm in Casper, Wyoming.

Flames raged for 48 hours and consumed 360,000 barrels of oil even after application of chemicals, according to the Associated Press.

Casper "was darkened by billows of smoke which spread over it," the Ogden Standard-Examiner, a Utah newspaper, reported. "The blaze continued under a downpour of rain which approached a cloudburst. ... More than one thousand men were rushed to the scene to protect other tanks."

Lightning struck again on July 2, 13 and 18,  according to a History of Natrona County, Wyoming.
