With recent interest in "fracking sand" in Minnesota, I thought folks might like to see a picture of "perfect" fracking sand:
Near the muddy banks of Hay Creek, a popular trout stream, are significant bluffs covered with a hardwood forest of oak, bass wood and black cherry trees.The picture is at the link.
Underneath the forested land is an increasingly valuable resource called “frac” sand, highly sought after for its size and strength. With perfectly round grains that look like brown sugar crystals, the sand is ideal for the oil and natural gas industry, which uses it to extract fuel from underground rock in a process called hydraulic fracturing, or fracking.
Minnesota locals are likely to kill the project. My hunch is there is "perfect" sand elsewhere.
