How do I identify this?

[+krabbcachers]

Hi everyone,

While caching on Maui last week I came across a few markers and decided to try benchmarking. I've been able to identify and log two of them, but can't locate this one. It was in lava rock on the beach near GC2HZED at N 20° 38.864 W 156° 26.537 and says ?EIBU HAWAII INC. SURVEY MARKER (the first letter is illegible). Can anyone help me identify it?

Thanks!

You can look here:

but the nearest mark in the NGS database I see to your specified cache location is about 1/4 mile away.

 

From the text you mentioned, it sounds like the mark was set by a private surveying company.
