19. Ponderosa Pine – Pinus ponderosa (look for a large tree with slightly yellowing bark)

Needles are 5 to 10 inches long and in bundles/fasicles of three, forming tufts at the end of each branch. Cones are oval, 3 to 6 inches long and 2 to 4 inches in diameter, with outwardly curved spines that make them prickly to handle. Bark is dark brown and rough textured in young trees and orange-brown with distinctive large plates in mature trees
