Hey, I found a benchmark!

Seeing as this thread has taken a serious turn for the loonie bin, I figured that it would be useful if someone other than the topic starter posted a comment. So, C-A why don't you share those pictures with us. Or should we prep the padded room for occupancy?

You can find them at:

You need to apply for an id/password but it's free and comes instantly. Takes a bit of poking around to get what you're looking for but if you persist you can get lists of all benchmarks in your area plus details on each of them The details make interesting reading and some are pretty old - over 100 years. From a thread posted by Jeremy somewhere else, one of these days we'll be able to log them on the site. Meanwhile I'm starting to build up a collection as there are a lot more benchmarks round here than there are caches by a factor of about 100:1 icon_biggrin.gif

I think I screwed up the BM name. Anyway, once you get onto the site this is the kind of information you can pull down. Here it is for the one I found (lots of geodesy information for those so inclined) Note use of NAD83 instead of the WGS84 we all know and love icon_smile.gif :
