There is a noticeable difference between the rugged eastern section which has shale rock and an intricate surface drainage pattern, and the western part, which is limestone and has, predominantly, underground rivers.

St. Mary is mostly hilly just under 13 per cent of its area having slopes below 10 degrees. This geological phenomenon is significant because of the effect it has on urban and agricultural development both of which are made more difficult in steeper gradients.

The coastal area of the parish stretches between Palmetto Bay and the White River. Here the vegetation is primarily deciduous.
