"South of Caen on the D562. After Saint-Remy, turn left and take the D133B. Between this road and the Yonne [sic, actually the Orne] river, after the railroad track, there is a quarry with arkose and quartz pebbles. Continuing down on the D562, past an airfield, turn right towards La Haute-Bruyère [Proussy], there is another quarry with chert." [Belot, 1978]
