A mountain that reaches elevation 755 m and underlain by Proterozoic quartzo-feldspathic gneisses some of which are graphitic and well exposed on the east and southwest slopes of the triangular peak of the mountain. Pods of graphite-rich diopside gneiss are also locally present (see Gates, 1961). One of these was prospected on the southern side of the mountain (see https://www.mindat.org/loc-265971.html).
