In 1974, the Lone Star Producing Company had been busy drilling for oil when it created the “Bertha Rogers hole” in western Oklahoma. You will find the man-made wonder in Washita County. How deep is it? Well, it reaches up to 31,400 feet below the ground, which means that it is nearly six miles deep.
