About this area:
High Acres Nature Area (HANA) consists of a collection of ponds, marshes, and two deciduous forests. The landfill was established in 1971, and is owned by Waste Management. The wetland and nature area was created during a later expansion. They have made the area and trails available for public use. There are several parking lots and trails are open from dawn to dusk. Restrictions are posted at the entrances. This area is full of wildlife and there is much to see and hear. (And smell!)
To solve the puzzle start on the YELLOW trail (aka the Christine Sevilla overlook) and follow the virtual stages.
