The southern Appalachian Mountains have the most locations and the tallest trees in the present range of Pinus strobus. One survivor is a specimen known as the Boogerman Pine in the Cataloochee Valley of Great Smoky Mountains National Park. At tall, it is the tallest accurately measured tree in North America east of the Rocky Mountains. It has been climbed and measured by tape drop by the Native Tree Society. Before Hurricane Opal broke its top in October 1995, Boogerman Pine was tall, as determined by Will Blozan and Robert Leverett using ground-based measurements.
