An amygdaloidal basalt dike-sill intruding the Devonian Millboro shale that outcrops along County road 21 approximately 5.5 miles south of the village of Sugar Grove, WVa. The intrusion is Eocene age, 45 MA+/- and up to approximately 10 feet thick. Amygdules greater than 1 inch in diameter are uncommon making this locality strictly a micromount locality.
This intrusion is part of a suite of Eocene dikes, diatremes and plugs centered on the areas around Monterey, Va and Ugly Mountain, Pendelton Co., WVa. Older, Jurassic and Cretaceous, dikes and plugs extend into the Shenandoah Valley to the vicinity of Harrisonburg and Staunton.
The road side outcrop south of Sugar Grove is the only one known to contain attractive secondary minerals. These are the youngest volcanic rocks east of the Rocky Mountains.
