Abstract
A general model for variance components in slope series comprise a mean, trend, periodicity, and autoregressive and noise terms. Series are generated for sixteen freshly deglaciated talus slopes by considering the slope angles of fixed lengths. Correlograms and power spectra show that most of the variance arises from low order autoregressive processes. This seems to imply a control of slope variance by processes other than supply and removal at least in the early stages of talus slope development.
