frac sand
Close-up view of frac sand (on the right) and a typical sand of similar grain size (on the left). Notice how the frac sand has a more uniform grain size, nicely rounded grain shapes, and a uniform composition. It is also a very tough material that can resist compressive forces of up to several tons per square inch. Grains in this image are about 0.50 millimeter in size.

Although most people believe that Vesuvius (79 AD - the Pompeii eruption), Mount St. Helens (1980), and Mount Pinatubo (1991) were enormous, they are very small compared to ancient eruptions such as Wah Wah Springs, Toba, Yellowstone, or Long Valley Caldera.

Utica Shale
The cross section above shows the subsurface position of the Marcellus Shale, Utica Shale and the continental basement rock. The line of cross section is shown as line A-B on the inset map. Note that the Utica Shale is about 2000 feet below the Marcellus under eastern Ohio but about 6000 feet below the Marcellus in south-central Pennsylvania. Also note that the Marcellus Shale potential source rock does not extend as far into Ohio as the Utica.
