  These appear to be US Navy Keystone PK-1 flying boats belonging to Patrol Squadron VP-1F, flying along the Na Pali coast of Kauai, Hawaii (note the Honopu Valley). The PK-1 was (like the Martin PM-2) an improved production version of the Naval Aircraft Factory (NAF) PN-12. VP-1F operated the PK-1 out of Ford Island, Oahu from 1932 to 1938.
