Mapping Mountains – Significant Height Revisions – The Fours

Minton Hill (SO 414 919)

This is the thirteenth post under the heading of Significant Height Revisions, and the following details are retrospective as the Trimble survey that resulted in this height revision was conducted on 2nd January 2015.

The thirteenth major height revision initiated from a survey with the Trimble GeoXH 6000 was conducted on a clear and sunny winter’s day in the hills of the Long Mynd, which are situated in Shropsire.

The hill is listed as a Sub-Four with 22m of drop in the 1st edition of The Fours published by Europeaklist in December 2013.  This drop value was based on the 453m summit spot height and 431m col spot height that appear on current Ordnance Survey maps.  The summit spot height is given to an ancient tumulus which is just one of a number of Tumuli that appear on the summits of the surrounding hills.

The hill can be easily accessed on a good tack from the north-west from the high road that crosses the extended summit ridge of the Long Mynd.  Or a more satisfying walk to its summit can start from the south-east from the small community of Minton, from where the hill gets its name from.

The name of the hill is Minton Hill and its summit height has been increased from its current Ordnance Survey map height, as prior to the survey with the Trimble GeoXH 6000 the hill was listed with a summit height of 453m based on the spot height that appears on current Ordnance Survey maps.  However, the result from the survey with the Trimble GeoXH 6000 gave the height of this hill’s summit as 455.4m (converted to OSGM15).

Therefore this hill’s new summit height is 455.4m (converted to OSGM15) which is 2.4m higher than its previously listed height which came from the 453m spot height on current Ordnance Survey maps.

The full details for the hill are:

Cardinal Hill:  Stiperstones

Summit Height (New Height):  455.4m (converted to OSGM15)

Name:  Minton Hill

OS 1:50,000 map:  137

Summit Grid Reference:  SO 41456 91920 
Drop:  23.3m
