Radiocarbon and OSL (optically stimulated luminescence) dates on the Beaumont/Prairie Formation range from roughly 28,000 to about 135,000 calendar years B. Mc Faddin Beach alone has produced more Clovis points than any single county in the state of Texas — over a hundred of them.Its nearest competitor, Gaines County in west Texas, has less than a third as many known Clovis points.Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.

A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.
However, by itself a fossil has little meaning unless it is placed within some context.
Mc Faddin Beach is a 32-kilometer long stretch of sandy beach in Jefferson County on the upper Texas Gulf coast, extending from High Island on the west to Sea Rim State Park on the east.
Sabine Pass and the Louisiana state line lie another 19 km farther to the east.
