Using a previously excavated exploration pit, Clark completed the following soil characterization: Soil field investigation was done to determine topsoil depth on areas mapped as Peetz, gravelly sandy loam, 5 to 20 percent slopes. These soils occur on terrace breaks and gravely ridges deposited during the Tertiary Period associated with the Ogallala Formation in Northern Weld County. This soil pedon description was taken in a Peetz, gravelly sandy loam, 5 to 20 percent slopes map unit. It had 3 percent slope and was on a nose slope of a ridge. The soil profile was moderately eroded. This soil does not correlate to the Peetz component but can be managed similar based on the somewhat excess drainage of the subsoil parent material.
