The Indian Signal Tree, an unusually formed Bur oak in Cascade Valley Metro Park, was reportedly shaped by Native Americans to serve as a marker on the old Portage Trail between the Cuyahoga and Tuscarawas rivers.

In winter, spring peepers hide under leaf litter and nearly freeze solid. Bullfrogs hide in mud at the bottom of ponds and lakes, breathing through their skin until spring arrives.
