To reach the tidal bench marks from Honolulu, take H-1 West and exit at "Hickam
AFB/Pearl Harbor" off ramp. Stay to the left and enter the main gate of Hickam
AFB.  Proceed straight ahead passing the flight line and staying in the left
lane which turns into Vickers Avenue.  Proceed on Vickers Avenue until it makes
a sharp left turn where it changes its name to Fort Kam Road.  Instead of
turning left, you proceed straight ahead through the main gate of Bishop Point
NAVSTA, and continue straight ahead for about 46 m (150 ft) where the gauge was
located at the inshore end of the pier A3/A4.  The bench marks were located in
the vicinity.

Mean Sea Level (MSL) is a tidal datum determined over a 19-year National
Tidal Datum Epoch.  It pertains to local mean sea level and should not be
confused with any other fixed island datum.

This tide station location has a local island datum.  Island datums
are specific fixed geodetic datums whose elevation relationship to local MSL
and other tidal datums may not be consistent from one location to another.

The Vertical Mark Number (VM#) and PID# shown on the bench mark sheet are unique
identifiers for bench marks in the tidal and geodetic databases, respectively.
Each bench mark in either database has a single, unique VM# and/or PID# assigned.
Where both VM# and PID# are indicated, both tidal and geodetic elevations are
available for the bench mark listed.
