U. S. Coast And Geodetic Survey epub Alaska Coast Pilot Notes from Yakutat Bay to Cook Inlet and Shelikof Strait (Classic Reprint)

From Cape St. Elias to the head of Cook Inlet and southward to Chiniak Bay, Cape Karluk, and Takli Island the principal points along the coast are determined by triangulation, and accurate courses and distances for coasting can be taken from chart 8502 (1910 edition). Some of the bays and arms are not surveyed, and their delineation on the chart is taken from the sketches of the early navigators adjusted to known points determined by later surveys. Vessels approaching Prince William Sound from southeastward generally make Cape St. Elias and pass 1mile or more southward of Southeast Rock. On page 8bearings and distances are given from Southeast Rock to the principal coast points of Southeast A laska. A current, constant so far as known, sets northwestward along the coast of Alaska as far as Cape St. Elias. This current is increased by southeast winds and decreased by northwest winds, but its estimated velocity under ordinary conditions is %mile an hour. This should be kept in mind, especially when approaching Cape St. Elias from southeastward, as a vessel will generally overrun her log when bound westward. Cape St. Elias to Cape Hinchinbrook. From a position 2miles southward of Southeast Rock a 295 true (W y Smag.) course made good for 67 miles will lead to a position y2 miles southward of Cape Hinchinbrook. An examination of the logs of several courses between Cape St. Elias and Cape Hinchinbrook indicates that the currents are influenced by the tides, being stronger with the larger tides, and that the current on the ebb has frequently, but not always, caused a southerly set, and the current on the flood a northerly set. On some occasions when the range of the tides was small no marked set of current was noted. Results seem to point to a stronger current toward Cape St. Elias than Cape Hinchinbrook. Surveying parties report a constant set south westward alon(Typographical errors above are due to OCR software and don't occur in the book.)
