Mount Price stands within a cirque-like basin cut into the plateau on the south side of the valley of Garibaldi Lake. This basin consists of a wall of granite, inclosing the volcano on its west and southwest sides. It is now almost completely filled up by Mount Price, but some small areas of its floor are exposed on the north side. The basin likely formed as a result of glacial action as its north side appears to have been almost certainly glaciated. It might otherwise have been attributed to explosive volcanism, but there are no fragmental materials around its margin which would confirm this.
