Geologic block model of half-grabens with dike.
This block features a stratified sequence of cherry, green poplar, purpleheart, and maple that are offset by two normal faults and cut by a vertical dike of black walnut. These strata are exposed in a dendritic pattern of broad, glacially-carved, U-shaped valleys.
