above the valley. A small number of artifacts are on display in a display case at Withrow Avenue Junior Public School. A plaque is affixed to the main entrance of the school on Bain Avenue. The eastern side of the park was also used as a landfill in the 1920s. A walk along Broadview Avenue shows the evidence of this in the form of green exhaust pipes to vent the methane gas from the former dump beneath the park. In the 1970s, the park was the original site proposed for a new 40,000 seat stadium, a project that would eventually become SkyDome. The plan was eventually abandoned, in part due to the strong objections of local Alderman John Sewell. In 1990, a grassy slope on the eastern side was planted with trees. This was the first public event hosted by the Task Force to Bring Back the Don. The slope is now moderately forested with trees averaging 3–4 metres in height. In 2002, Bring Back the Don created a small marsh at the bottom of the slope. Water collects there from the slope as well as from adjacent playing fields. Other restoration projects include trees planted along a berm adjacent to the Don Valley Parkway.
