Type Section  The type section of the Brora Sandstone Member is composite. The majority of the section is in the cliffs on the south bank of the River Brora [NC 905 039], with the uppermost beds exposed south of Ardassie Point. The base of the section is 540 m west of the A9 road bridge, running eastwards to the fault, 140 m east of the bridge. From the fault, there is a gap in the exposure until the uppermost beds are seen on the foreshore south of Ardassie Point [NC 911 038 to 913 041].
