It preserves fossils dating back to the Ediacaran period. It mainly contains turbidites, but is interrupted by a glacial diamictite, and tops out with sand and siltstones (these dated to 565 Ma).<ref name="Myrow1995a"/> It corresponds to the lower portion of the Connecting Point Group.<ref name="King1988aAvalonMap"/>

In some areas the Drook Formation continues from the base of the group to the base of the Mistaken Point Formation; elsewhere (in central / south Avalon) the Briscal, Gaskiers and Mall Bay Formations wedge in.<ref name="King1988aAvalonMap"/>
