Chestnut Oak - Quercus montana
The common name reflects the resemblance of the leaf to a Chestnut, but the teeth are more rounded and the leaves are widest at the tip. The bark is thick (the thickest of any eastern oak), ridged, and dark, and the trunk is variable, from short or branched to tall, depending on the habitat. This is a mountain oak, growing in the Appalachians at high elevations, often along ridges; it is adapted to rocky, dry sites. The acorns are long and reddish-brown, ripening in a year. A white oak, taller trees in good habitat are harvested for timber.
