The public path at Warren Park has been constructed on the original flood plain of the Cooks River. North of the path is a low sandstone cliff. An area of Potential Archaelogical Deposit (PAD) was identified in a sandstone overhang within the sandstone cliff. The sandstone overhang contains the Thomas Holt Burial Vaults. Above the sandstone cliff is a steep slope on top of which are private residences.

A stone artifact was found in Area 1. A dark grey/brown sediment overlies the situ shell and forms the matrix to the midden. The lowest section of in situ shell material overlies a sandy clay devoid to shell. Below this clay is sandstone bedrock.
