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.

| Devonian 358.9 - 419.2 Ma ID: 2744936 | Chemung Formation (redefined as Foreknobs Formation) Age: Devonian (358.9 - 419.2 Ma) Stratigraphic Name: Foreknobs Formation Description: Chemung Formation (Hall, 1839). Redefined as the Foreknobs Formation (Dennison, 1970). Sandstone and shale, dark-gray and greenish-gray, fine-grained, thin- to thick-bedded, lithic sandstone and interbedded greenish gray, fissile, clay shale. Minor quartz-pebble conglomerate, thin red sandstone, and locally, fossil shell beds. Very thin or absent in southwestern Virginia; thickens to about 2500 feet northeastward in Frederick County. Gradational contact with underlying Brallier Formation and equivalent to part of the Chattanooga Shale to the southwest. Redefined and described as part of the Greenland Gap Group by Dennison (1970).
