Built on a former municipal dump site, Riverview was operated by the city government as a ski park and was affectionately known as Mount Trashmore. Due to heat produced by decomposition of organic material in the landfill, it was difficult to keep snow on the hill. Operations were not profitable and the area was de-commissioned in the 1990’s. According to this website from 1997? it had 2 quad lifts, 2 handle tows, 8 slopes and 190′ of vertical.
According to the city of Riverview, the area is now used as a golf practice facility and landfill gas collected on the site is being used in a very successful green energy project in cooperation with Detroit Edison and generates enough electricity to power 3700 homes while reducing greenhouse gas emissions.
