Profile No. 2(minor soil type)
Horizon Depth (cm.) Description 
Aoo (0-1.25) Dark brown partly decomposed needles, twigs, moss, dead wood, etc. 
Ao (1.25-3.75) Dark brown well decomposed organic matter, with a large number of small feeding roots. 
A1 (3.75-6.25) Black friable Mixture of organic matter and mineral soil. Small granular structure, some of the granules having a soft core of concretionary iron. pH 4.55. 
A2 (6.25-27.5) Ashy gray clay with small granular structure at the top, becoming platy in the center of horizon and platy-granular combination in the lower part. The granules increase in size with depth, some having a core of concretionary iron. pH 5.31. 
A3 (27.5-35) Light gray clay with slight yellowish tinge when damp. Small fragmentary structure. More compact and heavier than horizon above. pH 5.01. 
B1 (35-41.25) Brownish yellow clay, the color being from concretionary iron particles with brownish centers and yellowish fringes on a gray background. Fragmentary structure and vertical cracking, the fragments being one inch in diameter capable of breaking down into small ones of the same shape. pH 5.52. 
B2 (41.25-53.75) Grayish brown clay with iron accumulation and fragmentary structure 1 1/2 inches in diameter. Compact and heaviest horizons in profile. pH 5.80. 
B3 (53.75-73.75) Clay with horizontal layering and some evidence of broken lamination. Alternating brown and light gray layers about 1/2-inch thick. Partly weathered parent material, compact and heavy. pH 6.40. 
C   Heavy varved clay with alternation of gray and dark brown layers. Main horizontal cleavage is about 1/2-inch apart. pH 6.55.
