Dépôt de versant polygénique associant avalanches et coulées de débris, dans la région de Zackenberg, au nord-est du Groenland. Les processus de versant peuvent perturber la datation des moraines, des amas de débris rocheux immobiles, libérés des glaces lorsqu'un glacier recule. En effet, ces processus de versant peuvent déposer sur une moraine, des blocs rocheux dont l'âge diffère de la mise en place de la moraine.
