Steinman Run


The 245-acre preserve is divided by an unpaved and gated section of Clearview Road. North of Clearview was clear-cut circa 1980.

Planning Your Walk

There are many deer trails, but follow the narrow, less-steep blue-blazed trail to prevent erosion. This trail ascends gradually from a 520′ elevation to a 740′ elevation among huge trees whose dense shade limits the understory.  The total trail length is estimated at 2.5 miles.

Nice views and scenic limestone outcroppings exist along the stream. The hilly terrain is underlain by schist. Soil type is dry, acidic, and crystalline with minimal nutrients. The badly eroded wide trail shows the glistening orange soil.

Watershed Facts

Steinman Run flows north to Trout Run to Pequea Creek, to the Susquehanna River, and Chesapeake Bay.

Autumn stars the brilliant reds of sumacs, the dark glistening red of sour gums mixed in with the yellows, pinks, and orange of maples, hickories, and tulip poplars.

On the ascending slope, red maples and oaks predominate, with tulip poplar, birch, beech, cherry, catalpa, and a fairly large, fruiting American chestnut (Castanea dentata), as well as wild grapevine (Vitus labrusca), heavy with tart, ripe fruit. The understory contains a few laurels, dogwoods, numerous fragrant spice bushes, and viburnums.

In autumn, look for the verdantly green Christmas fern. An occasional late-blooming white lychnis and yellow toadflax bloom in open areas, along with goldenrod and the seedheads of heal-all. White aster, smartweed, and white snakeroot are common.

A few mulberry trees and ironwoods can be found. As you approach Clearview Road look for a magnificiant stand of huge, straight, pawpaw (Asimia triloba).

The area south of Clearview has not recently been logged, so the trees are much grander. This area is a rich deep, wet marsh, alive with moisture-loving plants like skunk cabbage and trout lilies. The near hillside is a virtual white carpet of dwarf ginseng. Far less common is wood anemone. Solomon’s seal is common, along with several violet species and ferns such as interrupted fern and cinnamon, New York, hay-scented, lady, sensitive, and wood fern.

Steinman Run is pristine, with juvenile brook trout. June brings the flutelike call of the wood thrush.
