SOIL SURVEY OF PORTER COUNTY, INDIANA. 19 



The Clyde series is represented in the poorly drained depressions 

 within areas of the Carrington, Miami, and Crosby soils, where there 

 has bee: a i accumulation of organic matter in the surface soil. The 

 soil is black to very dark gray to a depth of 8 to 12 inches. The sub- 

 soil is mottled gray, drab, brown, and yeUow, with gray as the domi- 

 nant color. The substratum is calcareous till, and the lower subsoil 

 may be moderately calcareous. Only one type, the silty clay loam, 

 is mapped hi Porter County. 



The Waukesha soils are dark brown to black to a depth of 10 or 15 

 mches, with brown or yellowish-brown subsoils, which rest at a depth 

 of 2 to 3 feet upon a porous substratum consistmg of stratified beds of 

 sand and gravel. The fine sandy loam, loam, and silt loam types of 

 this series are encomitered in Porter County. 



The Plainfield series includes hght grayish brown soils with light 

 yellowish brown subsoils and a sandy substratum which affords good 

 to excessive underdrainage. The Plainfield fuie sand, fuie sandy 

 loam, and loam are recognized in this county. 



The Lucas series resembles the Plamfield somewhat in color of soil 

 and subsoil. It differs from that series in having a heavy clay sub- 

 stratum, so that the soil is not droughty. Faint gray motthngs 

 occur in the subsoil. The loam and silt loam members of this series 

 are mapped in Porter County. 



The Maumee series is characterized by black soils and a gray 

 subsoil which, with depth, becomes slightly mottled with brown and 

 yellow, or stained mth bog iron ore. The substratum consists of 

 stratified material which may be moderately calcareous. The 

 Maumee loamy fine sand, fine sandy loam, loam, and silty clay 

 loam are found in Porter County. 



The Homer series includes forested soils similar to the Crosby 

 soils in appearance, but differing from them in being derived from 

 lake deposits and in havmg less lime in the subsoil. The soU is 

 light gray, the subsurface is almost white, and the subsoil consists 

 of mottled light-gray and yellow or brown, heavy, plastic clay. 

 This series is represented by a single type, the silt loam. 



The Newton soUs are dark brown. The subsoils are yellowish 

 brown, more or less mottled with gray, and are underlain by grayish 

 stratified sand, silts, and clays which carry some hmestone material. 

 The Newton fine sandy loam, loam, and silt loam are mapped. 



The recent alluvium of the overflowed stream bottoms is classed 

 with the Griffin series. The surface sod is brown, and the subsoil 

 brown mottled with drab and gray. The silt loam is the only 

 member of this series encountered in Porter County,
