The Mysterious Wesley Chapel Gulf and Orangeville Rise (Orangeville, Indiana)

The Wesley Chapel Gulf, and the Orangeville Rise, provide a rare glimpse into the mysterious Lost River cave system. Researchers have conducted dye tests, to see where these waterways flow, but the dye never surfaces anywhere. It's theorized that this cave system could be as big, or bigger, than Mammoth Cave in Kentucky, which is over 300 miles long.
