Native to the midwest, the Chinkapin Oak can be easily recognized due to its small, yellowish, green toothed leaves. Unlike most oaks, the Chinkapin has unusually flaky, and fissured bark. Although this tree grows best in deep, well drained soil, it may also grow on dry limestone bluffs and hillsides. Also referred to as the Yellow Oak, early settlers used this tree for fencing, and fuel for steamships.
