How to reach:
Herendeen Island is located directly north of Little Koniuji Island; the two are separated by Northwest Harbor. All five(5) newly installed bench marks and the newly stalled HORCON benchmark are in close proximity to the shoreline and lie below a grass-covered ledge which parallels the shoreline. The tidal benchmarks span a linear region of approximately 250 meters (820 feet), beginning with ‘9459163A 2009’ in the north and ending with ‘9459163E 2009’ at the southernmost extent. The Herendeen Island tide gauge (#945-9163) is located on the southwest facing shore of Herendeen Island.
