This rock is a messy mixture of various poorly sorted particles of quartz, feldspars, occasional small rock fragments, as well as silts and clays. None of the particles greater than 0.08 inches (2 mm) in diameter and the silts and clays are not visible to the naked eye. The majority of the rock has a gritty feel to it. This rock does not dissolve with acid. There are no fossils present in this rock. This rock does not taste salty.
