To log a find on this cache
you must locate one of the several hundred CBN control survey
monuments located across Canada as indicated on the reference
maps available at the
Geodetic Survey of Canada web site. Detailed monument location
specification sheets can be downloaded for each monument which
includes the monument's coordinates and instructions on how to
locate it. Only monuments indicated on the above referenced map are
eligible to be logged as a find on this cache.
The coordinates listed above are not one of the control
monuments. They point to degree confluence unrelated to this
cache.
It is our intention that all of the CBN monuments located across
Canada be logged on this cache page.
You will need to provide the following information to
successfully log a find for this cache. You must provide the
monument station number, general location (city), and your recorded
position error as displayed by your GPSr as compared to those of
the published position. This will be a very good test of your GPS
receivers instantaneous accuracy at a known point.
You must also upload a photo of the monument with your GPSr
clearly visible. The photo must show enough of the surrounding area
to verify the location. You may also wish to include yourself or
your cache team in the photo(s).
We would like to have as many different CBN monuments found and
logged as possible. This will be a joint effort by cachers from all
across the country.
NOTE: The official recorded position on the monument reports are
given in DDD MM SS.ssss. That approximately equals 3 millimeter
precision. Also, note that the datum may be specified as NAD83,
which for these purposes, equals WGS84.
