The hills at this site inspired the design of the Great Seal of the State of Ohio. First depicted in 1803, the seal was often reconfigured until the present image was sanctioned by the Ohio General Assembly in 1967 and modified in 1996. The 1803 law prescribed a sheaf of wheat to represent Ohio's agricultural roots and a bundle of seventeen arrows to symbolize Ohio's place as the seventeenth state in the Union. In the background is a range of hills, including Mount Logan, as viewed from Thomas Worthington's estate, Adena, now a state memorial. The sun's thirteen rays represent the thirteen original colonies, and the Scioto River flows between the hills and the cultivated fields in the foreground. Tradition attributes the design to the cooperative vision of Thomas Worthington, the first U.S. Senator and father of Ohio statehood, Edward Tiffin, Ohio's first Governor, and William Creighton, Ohio's first Secretary of State. After an all-night meeting at Adena, they viewed the sun rising over Mount Logan and chose the scene for the state seal. Much of the land illustrated in the Great Seal of the State of Ohio now comprises Great Seal State Park.
