The
Huws – 100 great Welsh Hills under 2,000ft – Summit Relocations
The Huws – 100 great Welsh
hills under 2,000ft is
a subjective list outside of every hill having to be less than 2,000ft (609.6m)
in height. However, there were a number
of parameters the contributors wanted to meet, these include that the hills
should cover the whole length and breadth of Wales and that the list should
have the fullest variety of hills, both in height, prominence, geology, history
and difficulty.
The contributors to the list are Alex Cameron, John Gillham,
Myrddyn Phillips, Adrian Rayner, Mark Trengove and Rob Woodall and the
posts that have appeared on Mapping Mountains detailing the summit relocations
to this list appear below presented chronologically in receding order.
Ynys Llanddwyn (SH 385 626) - 1st summit relocation
There has been a Summit Relocation to a hill that is listed in the The Huws – 100 great Welsh hills under 2,000ft, with the summit height, bwlch height and their locations and the drop of the hill derived from a Trimble GeoXH 6000 survey and LIDAR analysis.

When the listing of The Huws was published by the Haroldstreet website and Mapping Mountains in March 2021, the summit of this hill was given to where the Lighthouse is situated at SH 38502 62500 in the south-western part of Ynys Llanddwyn and listed with a 17.4m summit height and a 6.3m bwlch height, with these values giving this summit 11.om of drop.
