Quaking Aspen Video Stock Footage
Quaking aspen is a tall, fast growing tree, usually 20–25 m (65–80 ft) at maturity, with a trunk 20 to 80 cm (8 inches to 2 feet 7 inches) in diameter records are 36.5 m (119 ft 9 in) in height and 1.37 m (4 ft 6 in) in diameter. The bark is relatively smooth, colored greenish-white to gray, and is marked by thick black horizontal scars and prominent black knots. Parallel vertical scars are tell-tale signs of elk, which strip off aspen bark with their front teeth. The leaves on mature trees are nearly round, 4–8 centimeters (1 1–3 1 inches) in diameter with small rounded teeth, and a 3–7-centimeter (1 1–2 3-inch) long, flattened petiole. Young trees and root sprouts have much larger (10–20 centimeters, 4–8 in long) nearly triangular leaves. Learn more about Quaking Aspen
