Benchmarks

[+mikdeni]

I'm in central B.C. Quesnel to be exact. Is there any known benchmarks in this area? I can't seem to find any using my home coords.

There are no Canadian benchmarks in the system yet. Do a search, it has been discussed.

Look here for a recent discussion.

 

This forum search shows a few more.

Canadian Geodetic Survey, it has a list of benchmarks. You can get the coordinates there and go find them. Sometimes on Geocaching .com there are locationless caches set up for finding of Canadian benchmarks in the area you live.

 

Good luck and have fun.

Yes! We have em, there called CGSN or Canadian gravity standardization network, stations.

I have located three in my area through this site and I will check them out with my gps.

They should work exactly like a Benchmark.

Thank you tons spud67

These are only the gravitational standardization network - there are 1000's of other benchmarks available to find. If you're in BC you are lucky - they have them on line here: http://mascot.gdbc.gov.bc.ca/mascot/

They even have a form on line to report marker condition etc.

One thing about the gravity network BM's is that the coordinates are often scaled off maps not surveyed (check the description of the BM) so you can't check the accuracy of your GPSr against them.

 

Gravity measurements are accurate however.

I checked out a couple of these gravitational stations today. One was partially covered with concrete on a sidewalk, but I could still see most of it. The other was supposed to be on the side of a cement block wall, but I could not find that one.

I felt uncomfortable looking for them with so many "muggles" nearby. I read in one of the forums to try wearing a reflective vest and carry a clip board and you are pretty much invisible.

Not quite as fun as I had anticipated. Will check out the one from "hard oiler" though.

I guess when you really think about it, there is no valid reason to worry about Muggles when hunting benchmarks. There is no cache container to inadvertantly expose so no worries of plundering or stealing. Also if anyone is curious enough to ask you what you are doing it's a perfect opportunity to explain the hobby. Also if you researched the BM ahead of time you can impress them with your knowledge of it's history.
