text: Looks like it is Waterdog Lake Open Space based on the official site here https://www.belmont.gov/Home/Components/FacilityDirectory/FacilityDirectory/10/702
  The other name probably comes from Google Maps, which appears to be wrong. It also seems as though the open space encompasses the lower area to based on their map here  https://www.belmont.gov/home/showdocument?id=7373 and that a small area there is considered hidden canyon park, but it is within the larger open space. So that probably needs to be changed also. I'll change the park name but leave the two notes open until some time passes for possible feedback.
