Abstract

While at work on the geology of Muscatine County last summer, the writer found some diatomaceous earth in the south bank of the creek which runs west near the south line of section fourteen, in Cedar Township. It is associated with a peaty layer, which overlies it, and which appears somewhat disturbed. This peat is overlain by fine laminated sand and silt, which here forms the base of the loess. Below the peat bed and the diatomaceous layer there is a white sand without a trace of ferruginous stains. Boggy conditions are indicated, or perhaps the conditions of a lake or pond. The diatomaceous earth itself does not lie in a continuous layer, but in a broken layer, or in small pockets, which are scattered. It has a peculiar dull, pink color, and this has lately enabled the writer to find small lumps of it in the peaty soil under the loess in Scott County, near Davenport. It was from this loess that the remains of a mastodon have been reported by Mr. Pratt.
