"(Coming from Romagnat). Exit Clermont on the N9 on the south side and immediately to the left take the D21 to arrive at Romagnat where one can find quartz at the place called 'Le Puy-Giroux'. Follow the D3 south and take the D52E left of the intersection to arrive at Gergovie." [Belot, 1978]

Small unauthorized workings on the eastern slope of the Gergovie plateau.
