Robb Hidden Canyon is a steep-sided ravine with a clear stream running through it. Beech and maple trees grow on the slopes, and from the recent tree planting at the top, visitors have a panoramic view of Ball Lake. Robert and Phyllis Robb donated the property to ACRES because they wanted to see the acreage remain undeveloped.
On the slopes beneath the trees grow bishop’s cap, jewelweed, rue anemone, wild phlox, blue cohosh, spring beauty, Virginia waterleaf and large-flowered trillium. In the trees are scarlet tanagers, indigo buntings, wood thrushes and rose-breasted grosbeaks.
