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 about 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, "121", on the west side.
One may drive to a spot quite near MON 121 thus:
Along Highway 3 east of Osoyoos, at coordinates 49.006462 -119.340580 turn south on Eagle Point Road.
Continue south to the very end of Eagle Point Road. The last 250 metres (~800 feet) is a narrow, overgrown, yet paved, road to a turnaround.
From there, bush-wack, first west, then south to find a reasonable route down to MON 121. You will have parked only about 85 metres north of MON 121 but well above it.
