In the past few years, largely because of increased freight rates, a keen interest in finding sources of high-silica sand has developed. The Geological Survey has received many inquiries about possible sources of high-silica sand in the state. Although published information on the geology of the formations that may contain high-silica sand has been available, economic information, such as quality, distribution, extent, and accessibility, has not been available.
