A 15 metre thick bed of limestone correlated to the Lower Cambrian Badshot Formation outcrops on either side of the Illecillewaet River in Albert Canyon, 10 kilometres southwest of Glacier National Park, about 34 kilometres east-northeast of Revelstoke. The bed strikes northwest for 1500 metres and dips 40 degrees northeast. The unit is overlain by mica schist and underlain by quartzite.

The bed generally consists of fine to medium grained, bluish grey limestone interbedded with some light grey limestone. Some of these carbonate beds consist almost entirely of dolomite. The deposit is cut by thin, white calcite veinlets. Occasional crystals of sphalerite are also present. A sample taken across the carbonate bed analysed 46.48 per cent CaO, 6.74 per cent MgO, 2.44 per cent SiO2, 0.61 per cent Al2O3, 0.44 per cent Fe2O3 and 0.01 per cent sulphur (CANMET Report 811, page 191, Sample 52).

The limestone was once used to produce lime in a pot kiln on the south side of the Canadian Pacific Railway track. The deposit was then investigated as a source of marble sometime in the early 1940s.
