Found after a short, but cold and brisk, walk from the C-Train. It wasn't too much trouble locating this brass cap once I figured out which side of the road to be on. Cap is well marked but also very well worn unfortunately from, I suspect, years of "unintentional" human interaction.
TFTBC. Photographic proof on its way to the CO now.
