In "A Report on Greene County" by Edward M. Shepard in Geological Survey of Missouri, Volume 12, Part 1, 1898, we find the following description of "Shaking Mound Spring" in n.w. 1/4 Sec. 15, T29N, R24W. "Here the water rises from the summit and seeps off all over the low mound, which is 12 ft. high, and 50 x 70 ft. in dimension." It "is most remarkable from the fact that it shakes all over when walked upon. Poles are easily sunk through the tenacious turf down to a distance of 6 to 10 feet into the black muck that makes up the bulk of the mound. **** Cattle are frequently mired in the bog. **** it is a rare example in the South, of the peat bog which is not uncommon in the more northern regions."
