Logan Elm State Memorial is said to be where, in 1774, Chief Logan of the Mingo tribe delivered his eloquent speech on Indian-White relations. The speech was supposedly delivered under a large elm tree. Considered to be one of the largest elms in the United States, the tree stood 65-feet tall, with a trunk circumference of 24 feet and foliage spread of 180 feet. It died in 1965 from damage by blight and storms. The tree's former location is marked by a plaque. Other plaques and monuments in the park honor Native Americans and early Ohio settlers.

Logan Elm Memorial is five miles south of Circleville, in Pickaway County, one mile east of U.S. Route 23 on State Route 361.
