GROUP OF SANDY LOAMS AND FINE SANDS. 
47 
COLOMA FINE SAND 
Extent and distribution .—While by far the greater portion of 
the material included in this type is fine in texture, there is a 
marked variation to this in some of the areas to the east of Clin- 
tonville. In these areas, the soil and subsoil both consist of 
very fine sand. Because of its extreme fineness and the pres¬ 
ence of organic matter, these areas approach in value the fine 
sandy loam. The chief areas of very fine sand are found in T. 
25 N. R. 15 E. in Section Nos. 14, 15, 21, 22, 23, 24, 25, 26, 27,* 
34, 35, and 36. 
The Coloma fine sand is confined to the eastern part of the 
county. The areas east of White Lake, south of New London, 
and those about 5 miles east of Clint onville are the most exten¬ 
sive. 
Description .—The surface soil of this type to an average 
depth of 6 inches consists of a brownish-yellow, loose, fine sand 
which contains only a limited amount of organic matter. The 
surface two or three inches has a somewhat darker color than 
the material immediately below this depth. This is due to the 
larger amount of organic matter near the surface. 
The subsoil consists of a loose yellow fine sand which extends 
to a depth of at least 36 inches, and usually to a much greater 
depth. In a few instances, traces of red clay were found a lit¬ 
tle below three feet. This is the same material which makes up 
the subsoil of the Superior soils. 
Topography and drainage.- —The soil has a gently rolling sur¬ 
face which in a few places becomes nearly hilly. It usually oc¬ 
cupies the most elevated positions and is thus exposed to pre¬ 
vailing winds. Where the surface is not protected the material 
is sometimes blown by the wind into dunes. In a few places 
wind action has rendered this soil unfit for cultivation. Such 
places, however, are of limited area. 
Because of the loose open character of this soil and the sur¬ 
face features, the natural drainage is very, thorough and in 
places somewhat excessive. 
Origin .—This soil has been derived largely from glaciated 
sandstone material. No limestone has entered into its forma¬ 
tion, and both soil and subsoil are in an acid condition. 
Native vegetation .—The original timber growth consisted 
chiefly of scrubby white and black oak, poplar, and pine.
