Tour Maryland Geology
Maryland's diverse landscape is an expression of her geology. The mountains, valleys, waterfalls, rivers, and dunes, islands and cliffs you see are produced by erosion. Bedrock, soil and sand are sculpted by water, ice and wind over thousands or millions of years to present us with breathtaking vistas throughout the state. Mountains, cliffs and highlands are formed of hard rocks where erosion removes softer surrounding rocks and sediments. Gorges, valleys and caves are the result of water grinding or dissolving away softer types of bedrock and sediments.
