The West Creek glacial headwaters walking tour (June 1, 2014, 2-5 pm) extends our knowledge back to the stream’s formative period, 23,000 to 14,000 years ago. The highland was one of the last Greater Cleveland areas to be covered by Erie ice and one of the first to see it leave. By 23,000 years ago, glacial ice was advancing up the Cuyahoga and Rocky River Valleys. About 15,000 years ago, with ice retreat, small streams began removing glacial debris. The upper creek is now a gathering of deep headwater ravines. In key ravines, we examine the debris of ice retreat. In the trunk stream, we explore the formation of post-glacial ecosystems. Led by Roy Larick (Bluestone Heights), Jessica Ferrato (NEO Sierra Club), Jenn Greiser (Cleveland MetroParks Watershed Stewardship Center).

- 2. West Creek is a success story in urban stream revitalization. In 1997, local residents formed one of the region’s first watershed advocacy groups. During the 2000s, the West Creek Conservancy helped establish the 326-acre Metroparks reservation and helped implement significant stream recovery projects. Opened in 2013, the Metroparks Watershed Stewardship Center is the current West Creek milestone. Many Clevelanders therefore know West Creek as an urban stream sustained with forward- thinking conservation practices. © 2014 Bluestone Heights West Creek Conservancy West Creek Conservancy

- 13. At the top of the rock sequence, surface runoff breaks through resistant Sharpsville Sandstone to dig deep into the underlying shale. The eroded rubble, a mixture of sandstone and shale plaquettes, then begins its descent to the trunk stream. geocaching.com

- Parma highland, without encumbrances
- Parma highland, without encumbrances
- Ice has advance across the area of low lying bedrock and has come to rest at the Berea sandstone ridge upon which the Henninger house sits (Rockside Rd) The Rocky River branch valleys are now paths of least resistance. Here we see ice working its way up the east branch valley.
- Ice is now how up on the highland, with a significant tongue filling the preglacial West Creek valley.
