Limestone outcrops along the beach on the southwest side of Blind Bay, on the south shore of Shuswap Lake. The limestone lies on the northern edge of a belt of limestone and schist of the lower Paleozoic Sicamous Formation (Mount Ida Group), which trends westward for 27 kilometres. The limestone on the beach strikes 005 degrees and dips 15 degrees west.

The beach exposures reveal fine grained, dark blue, thinly bedded, graphitic limestone displaying mica flakes along bedding planes. Numerous white calcite veins and a few quartz veins, 5 to 10 centimetres thick, cut across the bedding. Several thin, platy masses of dark blue dolomite are exposed at one point.

A chip sample taken across 3.0 metres of strata analysed 51.78 per cent CaO, 0.75 per cent MgO, 4.04 per cent SiO2, 0.59 per cent Al2O3, 0.66 per cent Fe2O3 and 0.06 per cent sulphur (CANMET Report 811, page 191, Sample 50).
