The following information from Pastscape.
"A blocked Old Red Conglomerate about 7'6" high probably from
the lower beds of the conglomerate, according to J G Wood.
"It is manifest that the Queen Stone is not in situ so far as
vertical position is concerned, but it is probable that it
rests on the surface of the old denuded beds of rock
underground." The sides of the rock are marked with deep
vertical grooves, which are almost certainly natural (of the
North Arrow at Boroughbridge, Yorks at SE 36 NE4). (3)
There is a reference in Hereford Museum to the excavations here
in 1926, together with a number of undistinguished worked
flints and a photograph showing that the striations on the
stone do not extend below ground level. Museum visited 14.7.52. (4)
Queen's Stone, a monolith. The block with the grooves in the
strata is of natural formation, but seems to have been placed
in its present position by human agency. (5)
A standing stone, which, judged from the depth of the grooves
of 0.2m, has been standing in its present position since
antiquity. It has a maximum height of 1.8m, is 1.6m wide and
0.9m thick. Situated upon level ground, at present under sugar
beet, within a loop of the River Wye. Published 1:2500 survey
correct. See GP. (6)
The standing stone described above (1-6) is visible on aerial photographs at the site stated by source 1 but was therefore not mapped for NMP. There do not appear to be any related features visible on the aerial photographs, such as sockets for other stones around the Queen stone."
