East Mountain is part of a long trap rock (basalt) ridge that extends from central Connecticut just west of Hartford to Mt. Tom in Holyoke, Massachusetts.   Many sections of this ridge support a rich and diverse flora, with a high number of uncommon or rare plant species.  We explore one section of this ridge --  the beautiful, upland oak-hickory forest along the Westfield/West Springfield town line.  Among the many species we hope to find are Aureolaria pedicularia, A. virginica, Viola pedata, both species of Chimaphila, Asplenium platyneuron, numerous different Desmodiums, and a wide variety of Asteraceae.  Though the ascent is somewhat strenuous, the pace will be leisurely.  Wear sturdy hiking boots.  Bring bag lunch, water, field guides, insect repellent.
