Wrike and Kearns (2007) reported that boulders and cobbles of miarolitic nepheline syenite occur in the bed of "Stotameyer Creek". On the USGS topographic map this drainage is called Stoutameyer Branch. Material was easily located in that part of the stream adjacent to Stover Shop road, just north of Route 250.

In this gray, dense brittle rock the cavities are highly flattened and occur in planar arrays. Wrike and Kearns (2007) note that the mineral assemblage in the miarolitic cavities is similar to that of the Buck Hill intrusion several miles to the northeast.
