cat face
n.— «Atzet stopped again, to drill into the bulging bark of a cat-faced sugar pine. The cat face is a ring of bulging bark that has grown to heal a scar left by a fire. Because the healing bark is loaded with pitch, it tends to burn more intensely each time fire sweeps past, and the cat face grows.» —“Some Species Need Forest Fires to Survive Plants Sprouting in Charred Oregon Woodland” by Jeff Barnard Los Angeles Times May 15, 1988.
