The station report above is taken from the Canadian Spatial Reference System (CSRS) on-line database maintained by Natural Resources Canada.

When it comes to waymarking, I would rather be seeking benchmarks than any other objects. Snow cover was minimal. I was headed out on Dolman Ridge for one more geocache. I put the aforementioned co-ordinates in my GPSr.

I was surprised to encounter only the post, especially because the station report describes a tablet or cap. The published co-ordinates were a perfect match. There was no snow cover. Perhaps fifty years of grass, moss and soil have covered over the disk.

The round trip from the open end of Dolman Ridge Road was 4 kilometres.
