The layers in the subsurface and bottom tier are commonly massive, but in some pedons they have weak thick platy structure. The materials are dominantly of hemic material. In some pedons, layers of fibric or sapric materials are within the subsurface and bottom tier but total thickness of either material is less than 10 inches. Some pedons have limnic materials at depths of 51 inches or greater. These are the Mooselake soils in the same family and the closely related Carbondale , Carlisle , Greenwood and Houghton series.
Mooselake soils have hemic material with mostly woody fiber.
Carbondale soils have sapric material dominant in the subsurface tier, and more than 10 inches of hemic material dominant in the subsurface and bottom tiers. Carlisle and Houghton soils have sapric material dominant in the subsurface tier and are mesic. Greenwood soils are dysic. Rifle soils are in bogs and depressional areas within ground moraines, end moraines, outwash plains, and lake plains. Slope gradients are less than 2 percent.
