Tinkham Mountain (8447feet) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.[3] This mountain's name was officially adopted in 1929 by the United States Board on Geographic Names to recognize Lieutenant Abiel W. Tinkham, the first white man to cross the Continental Divide at what would later become Glacier National Park.[4]
