The leaves, often triangular-shaped, are 3 inches to 6 inches wide with three to five lobes. They have shallow, sharp-angled clefts between the lobes and are coarsely serrated (with teeth). The leaf is shiny green on top and pale green underneath, and it turns orange-red to brilliant red in fall.

Young trees have smooth, light grey bark, which darkens and forms crags and ridges with maturity. The bark of medium-sized trees sometimes has a distinctive concentric ring pattern.

The sap can be used to make maple syrup, though it's not as high quality as that of sugar maples. Its wood is used for inexpensive furniture, firewood and railroad ties.
