From the Sugar Loaf to Llandovery the railway skirts the valley of the Brân, and below the town it continues in the same direction along the broad floor of the Towy towards Llandeilo, Carmarthen, and Swansea. Between Llandovery and Llangadock, 6 miles below, there is a main road on each side of the valley, that on the north side being the more frequented. The district is included in the 1-inch Geological Survey map, Sheets 41 & 42 N.W. (Old Series); in the 1-inch Ordnance Survey map, Sheets 212, 213, & 196, and in the 6-inch sheets, Carmarthenshire 10 S.E., 11 S.W., 18, 19 N.W., 26 S.E., 27 N.W. & S.W. The rocks near the town belong to the upper part of the Bala formation, but at the Sugar Loaf, 7 miles away to the north-east, a lower part of that formation, including the Dicranograptus -Shales, is rolled up in the core of aRead More
