COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Mudlick soils are on mountain sides. Slopes range from 8 to 45 percent. These soils formed in colluvium and residuum from diorite. The mean annual temperature is about 55 degrees F. The mean annual precipitation is about 46 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Killarney, Irondale, and Trackler soils. Killarney soils are loamy-skeletal, have fragipans, and are on mountain sides. Irondale soils are loamy-skeletal, moderately deep, and are on mountain sides. Trackler soils are moderately well drained, deep, and are on mountain tops.
DRAINAGE AND PERMEABILITY: Well drained. Permeability is moderate. The saturated hydraulic conductivity is moderately high. Surface runoff is moderate to high.
USE AND VEGETATION: These soils are used mainly for woodland. Native vegetation is oak-hickory forest.
DISTRIBUTION AND EXTENT: The St. Francois mountains region of the Missouri Ozarks (MLRA 116C). The series is of minor extent.
