Tinker's Creek was named after Captain Joseph Tinker, the principal boatsman of Moses Cleaveland's survey crew, who died in a boating accident while returning to New England in the fall of 1797.
Tinker's Creek Gorge
Thousands of years ago, when the Wisconsinian Glaciation retreated, dips and valleys like Tinker's Creek Gorge Elevation: were created due to erosion in the underlying shale. The awesome, severely sloped gorge sculpted by Tinker's Creek became a National Natural Landmark in 1967. A raised viewpoint over the gorge is easily accessible from the Gorge Parkway in the Cleveland Metroparks' Bedford Reservation. The stream is sometimes run inwhitewater kayaks and is arguably the most challenging creek in the state of Ohio.
Great Falls
The continuous downward flow of water erodes the underlying shale faster than the harder sandstone, causing sandstone outcropping collapses and features such as the 25-ft-high Great Falls of Tinker's Creek or Gates Mills Falls Elevation:, in Bedford, Ohio.
Tinker's Creek Aqueduct
Elevation:, on the National Register of Historic Places, was built to bridge the Ohio and Erie Canal over Tinker's Creek near its confluence with the Cuyahoga River. The aqueduct and surrounding area are subject to flooding by the Cuyahoga River and Tinker's Creek.
Tinker's Creek Viaduct
Elevation:, on the National Register of Historic Places, was a railroad trestle built to span Tinker's Creek near the Great Falls. A 510-foot-long stone archway was later built to channel the creek through the gorge, which was filled with landfill for the construction of a newer two-track railway. The top of the viaduct is still visible.
Watershed
Tinker's Creek is the largest tributary of the Cuyahoga River, the river which flows through Cleveland and into Lake Erie. Because of its glacial history, the course of the Cuyahoga River is unusual: it rises in Geauga County, Ohio, flows southward into the city ofAkron, Ohio, and then abruptly turns northward and flows into Lake Erie. Its course is shaped like a reversed "J," and Tinker's Creek, entering from the east, drains almost all of the land nestled in the hook of the "J" that does not drain directly into the Cuyahoga. The creek itself rises near Tinker's Creek State Park in Streetsboro, Portage County. The creek then flows through Twinsburg Township and Twinsburg in Summit County, and Glenwillow, Oakwood, Bedford Heights, Bedford, and Walton Hills in Cuyahoga County before its confluence with the Cuyahoga River in Valley View village near Independence. The 24 municipalities within the watershed are: Cuyahoga County
Tinker's Creek has eight major tributaries and countless unnamed smaller tributaries. From the headwaters moving downstream, the major tributaries are:
Bell Run
Hudson Springs
Pond Brook
Beaver Meadow Run
Mud Creek
Hawthorne Creek
Deer Lick Run
Wood Run
Geology
The walls of the Tinker's Creek valley expose four geologic layers. The youngest sediments, unconsolidated glacial till deposited on top of bedrock by the retreat of the Wisconsin glaciation12,000 years ago, occur in the upper portion of the watershed. These poorly sorted and poorly drained materials largely account for the marshes, swamps, bogs and fens that characterize the headwaters of the creek. Further downstream, at the Great Falls, the creek plunges over a cliff of Berea sandstonecomposed of tiny quartz crystals cemented with clay. Berea sandstone is about 330 million years old, and was generated by rivers bearing sand from higher ground to the east and north and depositing it in fan-shaped deltas in an ocean. These deltas eventually dried and were buried under subsequent sediments where they hardened into a layer of resistant rock. Cleveland shale underlies the sandstone. The shale is composed of extremely fine bits of quartz, clay and mica deposited at the edge of a sea. Ripple marks created by the sea's wave action are visible in the shale. The Cleveland shale is less resistant to erosion than the overlying Berea sandstone, so the creek was able to scour its impressive gorge once it had penetrated the sandstone cap—a process still occurring at the Great Falls. Downstream of the gorge, approaching the creek's confluence with the Cuyahoga River, the creek has begun to reveal Chagrin Shale, bluish-gray and opaque, laid down 360 million years ago.
