Coulter pine, or big-cone pine, is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico. Isolated groves are found as far north as Clearlake, California on the flanks of Mt. Konocti and Black Diamond Mines Regional Preserve. It is named after Thomas Coulter, an Irish botanist and physician. The Coulter pine produces some of the heaviest cones of any pine tree, up to 5 kg (11 lb) and among conifers is exceeded only by the cones of Araucaria bidwillii.
