Cycles of microlows and microhighs are repeated each 7 to 15 feet. The thickness of the A and ABss horizons varies from 30 inches in the microlow to 15 inches in the microhigh. Reaction throughout the A, ABss and BC horizons ranges from neutral in the microlows through mildly alkaline in the microhighs. Intersecting slickensides are common in the A ABss horizon. The A and ABss horizons have hue of 10YR, value of 3, and chroma 2 through 4.
Texture is clay.
The BC horizon has hue of 7.5YR or 10YR, value of 4, and chroma of 4. It ranges from clay to gravelly clay. The 2C horizon has hue of 7.5YR or 10YR, value of 4, and chroma of 4. Texture is very gravelly loam or very gravelly clay loam with 35 to 60 percent by volume of gravel. These are the Aguirre , Cartagena , Fe , Fraternidad , Guanica , and Poncena series in similar subgroups.
