The fact that soil mantles on hillslopes are often shallow, < 1-2 m, provides empirical evidence of a type of dynamic equilibrium between soil production and surface denudation, first identified by Nikiforoff (1949), since the conversion of bedrock to soil and subsequent denudation involves very little storage of soil material.
