A couple of bench marks I've found

[GalinAZ 0]

I am completely ignorant on bench marking but I took pictures of two that I've stumbled upon and thought folks in this forum might be interested in.

 

The first one is outside of Superior, Arizona along a road that parallels US 60.

 

The second is along the Denali Highway in Alaska and is not listed in the NGS Datasheet marker database.

 

I hope these are useful in some way!

Here's the gps coordinates on the Arizona one 33.2857889,-111.1818306

 

And here's the Alaskan one 33.2857889,-111.1818306

The first one is a land survey corner.  Some of those have also been measured for precise lat/lon and/or elevation, but that is a secondary usage and it isn't surprising if those don't show up at NGS.

 

The second one I would expect to be listed since it is a CGS disk, the predecessor name of NGS.

 

You gave the same cords for both.

The Alaska one is this:

Somebody needs to submit a POOR condition recovery report on this one to NGS.  Whatever bent the disk may have also altered its elevation, unless the 20-ft rod had hit bedrock.
