It crystallizes in the tetragonal system and forms yellow vitreous tabular crystals with perfect cleavage. It has a specific gravity of 3.3 and a hardness of 2.5.[2]

It was first reported from a Colorado Plateau-type uranium deposit near Moab, Utah. It is named after mine operator Jess Abernathy.[3]
