Part of this area, constituting the expansion south of Martinton, was produced by the breaking of the water over the moraine south and east of Hooper. Much sand was deposited by this overflow and this area south of Martinton contains many sand dunes. The soils of Iroquois county are divided into the following groups: (a) Upland Prairie Soils, including the upland soils that have not been covered with forests and on which the luxuriant growth of prairie grasses has produced relatively large amounts of organic matter. (b) Upland Timber Soils, including nearly all the upland areas that are now, or were formerly, covered with forests. (c) Terrace Soils, including bench lands, or second bottom lands, formed by deposits from overloaded streams, or by broad sheets of water arising from the melting of the glaciers. (d) Swamp and BottonuLand Soils, including the overflow lands or flood plains along streams, the swamps, and the poorly drained lowlands. Table 1 gives a list of the types of soil found in Iroquois county, the area of each type in square miles and in acres, and its percentage of the total area. For example, it may be noted that the brown silt loam of the prairie occupies sixty percent of the area of the county. The accompanying map shows the location and boundary of each type of soil, even down to areas of a few acres.
