Natural gas explosion?
February 28, 1990. Nowata, Oklahoma. On this date, residents of the Nowata area heard and felt an explosion. Its source was unknown until W. Mitchell checked to find out why Double Creek had backed up. He found a scene of curious devastation, which was then linked to the earlier explosion.
"The explosion blasted up large shale rocks, some estimated to weigh more than a ton, and filled about 150 feet of creekbed with shattered stone. Trees were blown down and the creek was partly blocked."The water level upstream from the site is 3 to 4 feet higher than below, although water is flowing under the rocks. .....
"'It looks like a giant mole went all under the ground,' Mitchell said, ...'There is no telling how big a hole is under there. You can hear water falling. Gas was bubbling up all along the bank. In one place the water was shooting up a couple of feet yesterday, like a fountain, but it has gone down now.'
"Large pieces of shale landed 20 to 30 feet from the creek bank, mud was blown outward from the explosion and pieces of shale as large as a big tennis shoe were found as much as 200 feet from the creek."
(Smith, Charlotte Anne; "Nowata Creek Blocked after Apparent Explosion," Tulsa World, March 4, 1990. Cr. P.A. Roales.)
Comment. A similar, though more violent, natural gas explosion occurred in 1890 in a river bed near Waldron, Indiana. See ESC4-X3 in the Catalog: Anomalies in Geology. For ordering information, visit: here.
