Pickering Passage is located in the South Puget Sound region and extends from Case Inlet in the North to Peale and Squaxin Passages and Hammersley Inlet at the southern end. This waterway has a swift current at maximum flood and ebb, flushing the passage rapidly. Depths are around 100 feet in the north end of the passage near McLane Cove. McLane Cove is mostly shallow intertidal zone with some depth at the entrance. The embayment receives weak flushing from Pickering Passage.
