State Highway Department Benchmark

Recommended Posts

I found a State Highway Department Benchmark at 47.56991 and 114.62930.

It has State Highway Department Benchmark and 2918.65 stamped on it.

Is this a logable benchmark.

Is it in a database somewhere on the geocaching website?

Thanks, Joe aka Ajax One

Every state sets large numbers of survey marks. Occasionally the accuracy with which they are set is up to the standards of the NGS, and the mark is submitted for addition to the National Spatial Reference System. Usually not. So Waymarking.com is about it for these, if the coordinates don't turn up anything. Good hunting.

I recently found benchmark labeled US Coast & Geodetic Survey Benchmark~ Elevation Feet Above Mean Sea Level~ E 116 ~ 1934

1. Is there some way to log this on the geocaching web page?

2. Is the 1934 the elevation at that point or is that the year that it was placed in the ground?

3. Terrain maps show the elevation in the area at about 3000 feet so how does 1934 fit in?

4. How do I find the "Benchmarks" data base.

Doesn't look Sanders County or Lake County in Montana have any MTDOT BM's with a PID. The closest one might be this one:

Thank you Unainah

1. Yes that is it-- E 116

2. Ok I see 1934 is the year monumented

3. Year 1934 makes sense now with the 3000 ft elevation shown on maps.

4. Ok -- I found that -- But how do I get from the E 116 stamped on the disk to that page with TN0305 on it?

I have read the coordinates at the site over the disc as 48.11755 and -115.41940.

I have a picture of it but don't know how to attach it to this post.

It looks exactly like the picture at http://www.geocaching.com/mark/

Added: Ok I have it logged as found on 1 Dec 12 and have attached a picture of it to my log entry.

Ajax One,

Any chance of a scenery shot to go with the brass? I tend to show lichen covered rocks or concrete setting posts.

Ok, Thanks kayakbird,

Well, it was very overcast and raining when I found this disk.

There is a pic of the weather station nearby on my geocache "Weather or Knot" GC427X4 web page.

My link

I go by there a lot and will get a pic of scenery on the next nice day.

Bye
