An excellent and unexpected gem of a site. Visited 1.5.2010 on a walk between Garn Caws and Carreg Waun Llech. There are two cairns shown on the OS map, which, approached from the west appear prominently on a local ridge, with the dramatic backdrop of the Black Mountains behind.
The two cairns themselves are in decent condition, although the fact that the north-eastern one is a small ring cairn is obscured by the stones piled in its centre.
The unexpected treat comes to the east, where the OS map shows nothing. In fact there are a huge number of small cairns (I counted over 20, but Coflein indicates that there are over 40). As I hadn't researched the site before coming, I knew nothing about these, but they are unmistakeably small cairns, presumably Bronze Age. They sit on a NE facing shelf, under which sit the lovely Carreg Waun Llech standing stone. The stone is not visible from the cairn field, nor can the cairns be seen from the stone.
Coflein description of the site (there are 28 associated monument records):
"The cairnfield is located in a natural hollow. It covers an area of some 450m (NW-SE) by 200m and possibly includes also two cairns separately described (300970-1).
The group comprises at least 40 stony mounds and two or three short lengths of stony bank. The mounds are of variable shape and size but average 5m in diameter and 0.4m high. The banks are short and discontinuous and appear to form no clear pattern."
The two main cairns (shown on the OS map) are described as follows:
Cwalca Round Cairn (SO15901734)
"Situated on a local summit, the cairn measures 8m in diameter and 0.4m high. It is composed of mixed grade stones consolidataed with light vegetation. It lies on a ridge at the W edge of a larger group of smaller and more irregularly shaped cairns resulting from agricultural clearance (NPRN 300972); it could be a member of this group."
Cwalca Ring Cairn (SO15911746)
"Situated on a local summit in open moorland, the cairn consists of a stony ring bank measuring 2.5m wide and 0.5m high with an overall diameter of 10m. The interior is occupied with loose stones.
The feature lies on a ridge at the W edge of a larger group of smaller and more irregularly shaped cairns resulting from agricultural clearance (NPRN300972); it, or at least the infill, could be a member of this group."
