Monumented along the Canada-U.S. border in 1905, the
Joint Report Upon The Survey and Demarcation of the Boundary Between The United States and Canada, by the
International Boundary Commission, tells us the following:
TYPES OF MONUMENTS
The monuments which mark and reference the boundary are of the following 11
types:
1. General type of cast—iron monument made in 1872—76 and in 1908—13. (Fig. 1.)
2. General type of aluminum-bronze monument made and set in 1904—9. (Fig. 2.) ...,
meaning that this border monument, from 1905, was made of an aluminum-bronze alloy. It is covered with silver paint. Raised lettering reads "Canada" on the north side, "United States" on the south side, "Treaty of 1846", etc. on the east side, with the monument's number, "166", on the west side.
One may drive to a spot quite near MON 166 thus:
From the Canadian Customs station at Cascade, proceed 1 kilometre northeast on Highway 395.
Turn right onto a dirt trail at 49.004369, -118.213130, just east of a driveway into a house.
Proceed down the trail generally south-southeast for about 550 metres, to the southernmost point on the trail. From there one may walk the next 30 metres to Monument 166. There is a fairly new page-wire about 2 metres north of the monument.
