sch.3-sec.6Meaning of bedrock

### sch.3-sec.6 Meaning of bedrock Bedrock is a continuous mass of consolidated rock that has been little-weathered. It may underlie a profile or protrude above the surface. Even when moist, it is usually too hard to dig with hand tools. It is not underlain by unconsolidated soil material and is distinguished from hardpans that are underlain by unconsolidated soil material. However, bedrock may be underlain by other layers of softer rock. Under the field handbook it is defined as an ‘R’ horizon. - 1 It may underlie a profile or protrude above the surface. - 2 Even when moist, it is usually too hard to dig with hand tools. - 3 It is not underlain by unconsolidated soil material and is distinguished from hardpans that are underlain by unconsolidated soil material.
