Alum Creek (Ohio)



Alum Creek is 58 mi long creek that runs north to south in central Ohio. The creek originates in Morrow County and then flows through Delaware County and finally into Franklin County, where it ends at Big Walnut Creek, which drains into the Scioto River. Alum Creek is a source of drinking water for the city of Westerville, Ohio.

History
The Alum Creek valley was inhabited by the Adena over 2,000 years ago. This mound builder culture constructed seven mounds along Alum Creek. The Lenape (Delaware) Indian tribe later established many settlements near the creek.

One of the first European settlers was Colonel Moses Byxbe, who constructed his home on Alum Creek in 1805. Colonel Byxbe owned or co-owned 38000 acres along the creek.

As a defensive measure during the War of 1812, local residents built four blockhouses in the area, including one on Alum Creek. The blockhouse, Fort Cheshire, was a 2-story log fortress, constructed so as to provide a place from which to shoot, drop boiling water, and defend against the threat of fire. The blockhouse was subsequently used as a schoolhouse and remained intact until the Civil War. The fort is commemorated by a bronze plaque where the blockhouse once stood.

Underground Railroad
The history of Alum Creek is also notable for its connection to the Underground Railroad, by which many slaves found their freedom. The Underground Railroad's Sycamore Trail ran along Alum Creek. Africa Road, near Alum Creek, is so named because of the nearby settlement of thirty freed slaves from North Carolina. In 2003 a plaque was erected in associated with The Ohio Historical Society to commemorate its significance.

Course
Alum Creek rises near Mt. Gilead, Ohio and runs south, where it joins with Bunker Run, Indigo Creek, and West Branch Alum Creek. It then flows into Alum Creek Lake, along with Big Run. It flows out of the reservoir through Alum Creek Dam, and joins with several tributaries. It flows through Westerville, Ohio and Columbus, Ohio, before joining with Big Walnut Creek with Blacklick Creek in Three Creeks Metro Park.
