Christy Mathewson (MLB HOF) played Pro Football from 1898-1902. More than two-thirds of the athletes who played at the top level of both sports did so in the early years of the NFL during the 1920s and 1930s.
Marine Terraces Marine terraces are formed by coastal erosion and reflect the history of the rise and fall of sea level over time. However, marine terraces are only found along coastlines where the land is rising. In areas where the land is sinking they are submerged or buried by younger sediments.
Coastal deposition is the laying down of material on the coast by the sea. It occurs when waves lose energy or when large inputs of sediment are made into the coastal system - perhaps due to the arrival of fluvial sediment at a river estuary. Wave refraction in bays also encourages deposition due to the dispersal of wave energy.
