Prairie Creek is the geologic source behind the Crater of Diamonds field, a lamproite diatreme with diamonds plus mantle and alteration minerals such as chrome diopside, epidote, garnet, hematite, and amethyst. Its value as a rockhounding landmark comes from that rare volcanic pipe, not from ordinary stream gravel. Reported finds include amethyst, diopside, epidote, garnet, hematite.
