Once located two miles north and 4 miles east of Gilbert on the banks of the Skunk River near today's Anderson Canoe Access is the H-Tree. The H-tree’s beginning was estimated to be the late 1800s. It was a graft (either intentionally done by Native Americans or by an accident of nature) of a red or slippery Elm and a white or American Elm. In the 1960s it became a victim of Dutch Elm disease but stood on, bare branched, for another 20 years finally collapsing in 1986. A cross-cut at that time revealed 200 rings.
