content: Brush Creek Chert, also known as Hughes River Flint, is a honey or light olive drab chert. When weathered it is a dull reddish brown. It has inclusions of cryptocrystalline and microcrystalline quartz, dolomite, pyrite, hematite, limonite, mica, sponge spicules, brachiopod valve fragments, and echinoderm plates. Depoits are flat lenses 6 in. thick. The limestone matrix at the oucropping has weathered to the point where huge blocks of limestone and Brush Creek Chert have separated, dropping downward, leaving small overhangs approx. 3 in. deep. This unconsolidated situation provides a dangerous threat to procurers of chert. The Brush Creek limestone outcrop is clearly visible on both sides of the ravine about 8 to 10 feet below the top. However, the highest quality chert is on the south or left side when facing upstream.
