The claim within Ohio was for a -wide strip between Lake Erie and a line just south of present-day Youngstown, Akron, New London, and Willard, about south of present-day U.S. Highway 224. The claim beyond Ohio included parts of Michigan, Indiana, Illinois, Iowa, Nebraska, Wyoming, Utah, Nevada, and California. The eastern boundary of the reserve follows a true meridian along Ellicott's Line, the boundary with Pennsylvania. The western boundary veers more than four degrees from a meridian to maintain the 120-mile width, due to convergence.
