CHINQUAPIN CREEK. Chinquapin Creek, also known as Egg Nog Branch, rises just east of Venable in eastern San Augustine County (at 31°28' N, 94°04' W) and runs southwest for 10½ miles to its mouth on Ayish Bayou, at the east edge of Angelina National Forest twelve miles south of San Augustine (at 31°21' N, 94°08' W). The surrounding nearly level flood plain is surfaced by loam and clay that supports dense forests of pine and hardwoods. The area is used predominantly as forest land. The creek is named for the chinquapin trees that grow along its banks.
