Martisco muck, on a less than 1 percent slope in a wooded area. Thickness of the organic surface layer ranges from 8 to 16 inches over marl. Depth to bedrock is greater than 60 inches. Some pedons have a sandy, loamy, or clayey substratum underlying the marl below a depth of 40 inches. The 0a horizon is neutral or has hue of 5YR through 10YR, value of 2 or 3, and chroma of 0 through 2.
Structure is weak fine granular to moderate coarse subangular blocky.
Reactions ranges from slightly acid through moderately alkaline. Content of mineral material ranges from none to 80 percent and is dominantly silt, very fine sand or fine sand. The 0a horizons are commonly continuous vertically, but in some pedons there are alternating thin strata of organic material and marl. Some pedons have a thin Oe horizon. The 2C horizon is neutral, or has hue of 10YR through 5Y, value of 4 through 8 and chroma of 0 through 2, with or without mottles.
