After visiting the degree confluence at 22°N 160°W, my wife and I continued on to Lehua and looked for this survey marker.
We did not find the survey marker. The top of Lehua is barren and no evidence of the survey marker was found. It probably has been destroyed. We are reporting it as not found, because the NGS prefers to see the remains of the actual marker before classifying it as destroyed.
We did not find reference mark 1. We did find an empty 1.5" pipe set in concrete at N 22 01.138 W 160 05.887, which corresponds to the location given for reference mark 1. This probably was the setting for reference mark 1, so reference mark 1 was presumably destroyed.
We found reference mark 2 in good condition at N 22 01.144 W 160 05.908.
The wooden tower with light no longer exists. The current Coast Guard light, named Lehua Rock Light, is on a metal post and is located at N 22 01.140 W 160 05.901.
We also found an unknown disk, stamped "ROCK 1972", at N 22 01.129 W 160 05.793. This presumably was left by the U.S. Navy recovery in 1972.
