One-half mile east is the site of the former BIG EAR radio telescope. Designed by Dr. John D. Kraus, pioneering radio astronomer at Ohio State University, it had a collecting area of 340 by 70 feet (104 by 21 meters). The observatory was completed in 1963. The Ohio Sky Survey recorded here between 1965 and 1972 was the most accurate, reliable, and complete mapping of cosmic radio signals (the “radio sky”) for many years. BIG EAR gained fame for its ability to detect quasi-stellar radio sources, or “quasars,” and for its discovery of some of the most distant objects known. This observatory conducted a 24-year continuous search for evidence of extraterrestrial intelligence, during which the famous “Wow!” signal was received in 1977. BIG EAR was demolished in 1998.

This covered bridge in the oldest still (1962) standing in the state and the last of the “double-barreled” spans in Ohio. It was built across Seven Mile Creek on the Old Camden Road in 1829-30 by Orlistus Roberts and J.L. Campbell. Its three burr-arch trusses built of native oak and poplar with a clear span of 73 feet, support the double roadway. This plaque has been erected to give due honor to the early timber covered bridge builders of Ohio and the important spans they constructed. [This side also contains a bridge illustration in the upper left corner]

This covered bridge, spanning Salt Creek in Perry Township, Muskingum County was erected in the 1870s. It is a splendid example of an Ohio covered bridge built with Warren type trusses. It is being preserved as an important illustration of the sound, fine craftsmanship of the early bridge builders of Ohio. This plaque has been erected to give these men the honor they greatly deserve.

Seven-year-old Jonathan Alder was captured by a Native American war party in Virginia in 1782 and taken to a Mingo village north of the Mad River in Ohio where he was adopted by an Indian family. He remained with the Indians until after the 1795 Treaty of Greenville ended the Indian Wars in the Ohio Country. As white settlers entered the region, Alder frequently served as an interpreter. In 1805, he journeyed to Virginia and was reunited with his original family. He returned to Ohio with his new wife, Mary Blont, and built a cabin on Big Darby Creek. His cabin is now at the Madison County Historical Society Museum in London. Alder is buried in Foster Chapel Cemetery.

Brigadier General Albert G. Jenkins of Virginia, with 350 Confederate cavalrymen, crossed the Ohio River near this point on September 3, 1862, and advanced to Racine. After occupying the town for a few hours and after seizing a dozen horses, the troops re-crossed the river at Wolf’s Bar. This was the first invasion of Ohio soil by Confederate troops during the Civil War.

Sounds of boat horns and brawling packet crews resounded for many years at this lock and 142 others on the Ohio and Erie Canal. The canal was a 308-mile water toll road built between 1825 and 1832 from Lake Erie at Cleveland to the Ohio River at Portsmouth. The early growth of Akron and Massillon was due to the canal. Railroads caused its decline and the flood of 1913 destroyed its usefulness.

This covered bridge, over Middle Run, Elkrun Township, Columbiana County, is the shortest covered bridge in the United States still standing on a once-used public highway, having a clear span of 19 feet and 3 inches. It is an example, rarely found covered, of the simplest, most basic truss design, the two-panel king post truss. It has withstood the rigors of time and traffic since the 1870s and stands in eloquent testimony of the fine craftsmanship of the early Ohio bridge builders.

You are standing on the famous portage, carrying-place between the Cuyahoga and Tuscarawas rivers. The two streams and the portage across the watershed formed an early route between Lake Erie and the Ohio River. First the Indians, then French and English traders and trappers, and finally American settlers and travelers carried their canoes and packs across this narrow strip of land in passing, by way of the rivers, between northern and southern Ohio. The portage was a part of the defined boundaries in the treaties with the Indians made at Fort McIntosh (1785), Fort Harmar (1789), and Green Ville (1795). Use of the portage was discontinued in 1827 when the Ohio and Erie Canal was built along the old trail. Today, modern Akron streets–Portage Path and Manchester Road–follow the approximate route of the original portage.
