Mapping Mountains – Summit Relocations – The Fours - The 400m Hills of England


Addlebrough (SD 947 878)

There has been a Summit Relocation to a hill that is listed in The Fours initiated by an Abney level survey conducted by Jim Bloomer.  The Fours is the title for the list of 400m hills of England and is co-authored by Myrddyn Phillips and Aled Williams with the 2nd edition of the booklet containing this list published by Mapping Mountains Publications on the 24.04.18.

The criteria for the list that this summit relocation affects are:

English hills at and above 400m and below 500m in height that have a minimum 30m of drop.

The name of the hill is Addlebrough and it is situated in The Northern and Central Pennines (Region 35, Section 35B) with its Cardinal Hill being Whernside (SD 738 814), and it is positioned with the A 684 road and the River Ure to its north and the B 6160 road and the Bishopdale Beck to its south-east, and has the village of Bainbridge towards the north north-west.

As the upper section of the hill is a part of designated open access land an ascent is feasible from most directions, with public footpaths accessing the open access land from a minor road to the west of the hill which gives a relatively easy route to the summit.

The summit area of this hill has an uppermost 480m ring contour on contemporary Ordnance Survey maps positioned at SD 945 880 and this is the position given for the summit of the hill in the 1st edition of The Fours published by Europeaklist in December 2013, however since the 1st edition of this list was published the summit has been Abney levelled and the position of its high point confirmed as SD 94746 87874.

Therefore, the confirmation of the relocated summit position is at SD 94746 87874 and this consists of featureless ground just south of a wall, this position is approximately 250 metres south-eastward from where the summit position was given in the 1st edition of The Fours.
