South is in a dip [Pic]. The southern horizon is very distant and fairly uniform.
Thus the profiles of nearer hills may make more reliable markers in this direction.

It looks as though the other end of the range starts with the cross-quarter at the foot of the slope but only the major end has been accurately surveyed because the remainder is obscured.
Almost the entire eastern horizon is hidden behind a field boundary but it is low and distant.

range could be accurately surveyed. The remainder was either obscured or too hazy.
South-westwards, a distant hazy horizon is just visible above nearer ground.
The major eighth is at a local high point and, were this nearer ground covered with trees,

and the winter cross-quarters would be at intersections of the near and far horizons.
To the west, most notably, the equinox is on a hilltop and the quarter-month south of it is at the bottom of a major dip.
The north-western quadrant is clearly the major focus here.
Foel Cwmcerwyn, the highest of the Preseli mountains, marks the minor standstillLunistice positions vary cyclically over an 18.6 year period but are fairly static for more than a year at either end of the range

Being situated close to the ridge crest, Carn Besi would have been visible on the south-east horizon from Gors Fawr Stone Circle.
There are many prehistoric tombs in the U.K. but the only other surveyed ones are:
- Bryn Celli Ddu Chambered Tomb on Anglesey.
- Stoney Littleton Long Barrow in Somerset.
- West Kennet Long Barrow in Wiltshire.
