Boulders of basalt with white, trapezohedral phenocrysts up to 2.5 cm in diamter, which were thought to be leucite, were reported to occur where Horsefly Creek meets Quesnel Lake (Hoffman, 1896), but they were later recognized to be analcime (A.M. Soregaroli, 1973 - quoted in Currie, 1976a. p. 41). A further, but unconfirmed, occurrence of leucite-bearing volcanics from the headwaters of Horsefly Creek on Big Timothy (Big Takomkane) Mountain is also reported by Currie (1976a, p. 41).
