Description

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).

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 375-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

Upper West Creek Lower West Creek Parma Highland Upper West Creek is well placed for viewing the effects of the late Ice Age. The stream drains the front of the Parma highland, a bedrock massif lying between the Cuyahoga and Rocky River valleys. South

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. Glacial effects are well preserved. Upper West Creek Lower West Creek © 2014 Bluestone Heights Parma Highland North

By 23,000 years ago, glacial ice was advancing up the Cuyahoga and Rocky River Valleys. © 2014 Bluestone Heights Parma Highland North

Soon after, ice pushed soft rubble up a small pre-glacial West Creek valley. By 22,000 years ago, the highland was completely covered in ice. © 2014 Bluestone Heights Parma Highland North

About 15,000 years ago, with ice retreat, small streams began removing the rubble. The upper creek is now a gathering of deep headwater ravines. © 2014 Bluestone Heights Sharon Sandstone terrace Berea Sandstone terraceNorth

In key ravines, we examine the debris of ice retreat and the scouring of bedrock outcrops. geocaching.com

In the trunk stream, we explore the formation of post-glacial ecosystems on raw, debris-laden terrain. West Creek Conservancy geocaching.com

We summarize historic land use, including the local quarrying of Sharon and Berea sandstones. John Froelich house, 7095 Broadview Rd. Built c. 1855 of locally quarried highland sandstone. © 2014 Bluestone Heights

Last but not least, we review recent land use results of current conservation and storm- water practices in park development. To ensure that West Creek retains its formative legacy
