Medina's Tank Testing Ground

In the midst of the Cold War, America was ramping up their military strength. Part of the that buildup was producing bigger, faster, better tanks. And what is now known as the IX Center, was in the 1950's, the site of the GM Cadillac Tank Plant, charged with building M41 Walker Bulldog tank.

While the tank was under production, GM needed a place to test the tanks that would reflect the rough areas they would need to travel during war conditions. An area near the Hinckley-West Richfield border was just what the company needed.

In February 1951, Cadillac announced that the location, just off State Route 303, was ready for use and already had a tank on site. Called the Cadillac Ordnance Proving Ground, the site had everything needed to give the tanks a good work out: hilly terrain, deep ravines, switchbacks, dense brush and water hazards. Two test courses were designed to replicate field conditions.

The spring rains were particularly effective in testing the tanks', and the drivers', abilities to maneuver through the muddiest conditions, as illustrated in this photo from the April 30, 1954 edition of The Medina Gazette.

The Army ceased production of the Walker Bulldog in 1955. A few years later, GM Cadillac turned over the tank plant to its Allison Division. They produced the M-551 Sheridan tank until 1972.

They continued to use the Proving Grounds near Hinckley until 1970.

By December of 1970, the Army had abandoned the site. Hinckley and Richfield Township officials worked together to obtain the land. It took until 1978 for the federal government to donate the land for recreational use.

Named "Rising Valley Park", the two townships jointly operated the park from 1978 to 2005, when they decided to terminate the cooperative agreement. 44.7 acres went to Richfield and 188.3. acres became part of the Cleveland Metroparks.

You can almost see the outline of the old tank testing grounds in this Google image.

I see a field trip in my future!
