A northwest-trending belt of dolomite of the Middle Ordovician to Silurian Beaverfoot Formation is well exposed along the Trans- Canada Highway (Highway 1), 1.5 to 3 kilometres west of Glenogle Station of the Canadian Pacific Railway and about 9 kilometres east of Golden, in the canyon of the Kicking Horse River. South of the river, the dolomite is thrust faulted against limestone of the Upper Cambrian to Middle Ordovician McKay Group to the west and flanked by quartzite of the Middle to Upper Ordovician Mount Wilson Formation to the east. The strata are overturned and dip moderately to steeply eastward. The belt continues northwest of the Kicking Horse River for 12 kilometres where it becomes complicated by recumbent folding and thrust faulting.

The dolomite exposed along the highway is massive to thin bedded, light to dark grey and fine grained. Chert is abundant in places. Two grab samples analysed as follows (in per cent) (CANMET Report 811, page 191, Samples 53, 53B):

------------------------------------------------------------------
Sample    CaO        MgO       SiO2     Al203     Fe2O3    Sulphur
 53      31.21      21.02      1.28      0.41      0.28      0.01
 53B     31.09      20.71      1.10      0.29      0.46      0.01

Sample 53 is of very fine grained, light grey dolomite and Sample 53B is of faintly mottled, light grey dolomite.

The Glenogle quarry was operated by the Canadian Pacific Railway, 1.6 kilometres west of Glenogle Station, to supply dolomite for use as railroad ballast, sometime during the early 1940s.

In 2017, 92 Resources Corp. completed a rock sampling program on the property. A total of 60 metallurgical and 53 frac sand samples were taken from three areas on the property containing the occurrence. Highlighted results included zones of 99 to 99.5 percent silica content (Lindinger, L. (2018-03-28): Technical Report of Exploration Activities on the Zim Frac-Wil Property).
