I'm looking for information on something called Mog Mathon (I'm sure I've spelled it incorrectly), supposedly a dragon that lives within the Earth, set loose upon the first Caddo men to come above ground. I haven't been able to find out why, but we've been told that it burned all man's crops so he'd respect the Earth. Now the dragon dwells beneath the Earth, warming the water of Arkansas' Hot Springs. Any additional information (that's NOT word-of-mouth) would be GREATLY appreciated. Putting together info for a video.
