The Baker Creek phosphate occurrence is located on a steep east-facing slope, southwest of the Burnt River and approximately 4 kilometres northeast of Mount Kinney.
Regionally, the area is underlain by a series of folded and northwest-trending sedimentary rocks comprising mudstone, siltstone, shale and fine clastic sedimentary rocks of the Devonian to Mississippian Besa River Formation; limestone, marble and calcareous sedimentary rocks of the Mississippian Prophet Formation; undivided sedimentary rocks of the Carboniferous to Permian Stoddart, Fantasque and Kindle formations; and calcareous and fine clastic sedimentary rocks of the Triassic Spray River Group.
A 1-metre-thick sandstone bed of the Permian Mowitch Formation, containing 20 to 30 per cent phosphate nodules by volume, overlies a chert bed of the Permian Ranger Canyon Formation. The Mowitch and Roger Canyon formations are correlative with the Permian Fantasque Formation.
A grab sample from this locality contained 11.66 per cent phosphate (P2O5) as fluorapatite (S. Butrenchuk, personal communication, 1991).
