Part 3 - Gallery of the Middle Section



Periwinkle (Vinca minor) is commonly planted in parks especially near bridge abutments and other architectural elements. The Periwinkle planted over a half century ago in this old and remnant section of Devil's Hole State Park shows how this plant can dominate the soil surface in disturbed areas in full and partial shade.

On the other hand, opportunistic and pioneer native species can also dominate. In the area adjacent to the Periwinkle, the ground in this area is covered completely with one of the three common natural ground cover species. The first two are Virginia Creeper (Parthenocissus vitacea) and River Grape (Vitis riparia). The third is this species shown: Poison Ivy (Rhus toxicodendron).



Looking across the Devil's Hole cove from the middle section, the masonry constructed as a stream outlet and subsequently blocked is visible through the surrounding shrub layer. Looking at the south rim of the cove.


This alien Hawthorn is a favored horticultural species planted in many of the State Parks along the Niagara River: Crataegus monogyna. It is abundant in the middle and downstream remnants of old Devil's Hole.


Another Hawthorn species also planted is Crataegus phaenopyrum, both abundant in these sections. No other native Hawthorn has the leaf shape of these two species - a helpful characteristic in a group notoriously difficult to identify.



Several specimens of Red Cedar (Juniperus virginiana) have sprung up near the edge of the Niagara Gorge in this section.


A remnant of the old masonry wall: this is a pier, indicating that perhaps the intermediary sections between piers were pipe-sections, not continuous masonry.
