Other collections of upright stones, arranged in lines, or placed without apparent order, are found in several parts. On Sleights moor there are a remarkable assemblage of this description, called the high Bride stones, forming a kind of irregular line, and perhaps originally an avenue. There were 11 upright stones in this cluster some years ago: at present there are only 6 standing, and 3 or 4 that have fallen down: none of them exceeding 7 or 8 feet high.

The only other stone circles known to me are the High Bride Stones, near large and small barrows, at an altitude of 900 feet on Sleights Moor. To-day six only are standing, and at least fourteen are fallen. The most conspicuous stone is 7 feet high and terribly weathered. Near it lie three others nearly as long, and another about 4 feet long, which together with the upright stone form a semi-circle. Some distance to the south stands a solitary stone about 3 feet high. Thirty yards north of the semi-circle, three upright stones from 2-3 feet high form part of another circle, the remaining stones of which to the number of at least eight have fallen over and are more or less hidden in the heather. Further north are two fallen stones and still further in the same direction is a monolith 6 feet high high and deeply rain furrowed. Thus the High Bride Stones, which from north to south extend about 150 yards, seem to have originally consisted of adjacent circles, one of large, the other of smaller stones, with outlying monoliths. Despite their deplorable state they are the most impressive standing-stones in North-east Yorkshire.

At the northern end, on Sleights Moor, the High and Low Bridestones offer an interesting contrast; the latter are natural formations, curious weathered blocks of sandstone, some of which look like huge toadstools, raised on narrow stems. The High Bridestones, on the other hand, though hardly so fine to look at, are human handiwork, a stone circle of the Bronze Age; the individual monoliths are many of them very large, and although today more than half have fallen, this remains easily the best sanctuary of its kind in this part of the country.

Note. The natural formations referred to by Hawkes are located in the Dalby Forest. The Low Bridestones on Sleights Moor are a number of low standing stones that have been interpreted as prehistoric walling.

On a bleak, often waterlogged limestone pavement the High Bridestones have been all things to all men. Even the name is deceptive. It has nothing to do with nuptials, sex or fertility symbolism. It relates to Brigid, the goddess of the Bigantes, the Iron Age tribe that inhabited this grim, windblown region. There have been varying interpretations of the eleven stones of which six stand. They have been called the remains of two stone circles with outliers to the north and south; standing stones among natural outcrops; and a ruinous double row or avenue. They may, instead, be the wreckage of two Four-Posters.
A. At the north-west and at right-angles to the line like a terminal stone on Dartmoor there is a single stone 5ft 2ins (1.6m) high. To its south-east, 190ft (58m) away, are three stones at the corner of a rectangle 25ft by 20ft (7.6 x 6.1m) from which the north-east stone is missing. The tallest pillar, 4ft 5ins (1.3m) high is at the south-east. The setting resembles a ‘christianised’ Four-Poster.
B. A further 76ft (23.2m) south-east is a low, loose stump and 28ft (8.5m) beyond it is a very questionable Four-Poster in such a disastrous state that little can be claimed for it. The biggest stone, 7ft 6ins (2.3m) high, still stands and around it in confusion lie three slabs, 8ft 4ins, 10ft and 7ft 6ins (2.5, 3.1, 2.3m) long. If this megalithic disaster had have been a Four-Poster its rectangle would have been about 15ft by 13ft (4.6 x 4m). Like the more identifiable setting to the north-west its sides would have been roughly aligned on the cardinal points.
