Logan Elm State Memorial is said to be the site 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 U. S., the tree stood 65 feet tall, with a trunk circumference of 24 feet and foliage spread of 180 feet. It died in 1964 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.
