Dow Low (SK 100 675) – 400m Sub-Four addition
There has been an addition to the listing of The Fours due to analysis of data on the OS Maps website, which is the recent replacement for OS Get-a-map. The Fours is the title for the list of 400m hills of England and takes in all English hills at or above 400m and below 500m in height that have a minimum 30m of drop, the list is co-authored by Myrddyn Phillips and Aled Williams and the 2nd edition of the booklet containing this list was published by Mapping Mountains Publications on the 24th April 2018.
Accompanying the main list of The Fours are three categories of sub hills, with this hill being added to the 400m Sub-Fours. The criteria for 400m Sub-Four status are all English hills at or above 400m and below 500m in height that have 20m or more and below 30m of drop.
Prior to analysis of data on OS Maps this hill was not classified as its present construction is the result of mining activity from the Hindlow Quarry; therefore it does not possess any upper ring contours on the Ordnance Survey 1:50,000 Landranger or 1:25,000 Explorer maps.

The land where the summit of this hill is situated is positioned on that associated with Dow Low (SK 093 675) and therefore it is listed by the same name. The hill is situated in the Southern Pennines and is placed in Region 36, with its Cardinal Hill being Axe Edge (SK 035 706). The hill is positioned with the A 515 road to its north-east and has the town of Buxton to its north-west.
As the summit of the hill is not a part of designated open access land and a part of a working mine permission to visit should be sought, for those wishing to do so a public footpath passes relatively close to the summit of the hill and can be accessed from near Dowlow Farm to the north-east.
The addition of this hill to 400m Sub-Four status is due to the analysis of data on the OS Maps website coupled with analysis of imagery on Google Earth concluding that the hill is solid and stable. The mapping on the OS Maps website gives contour intervals at 5m which has enabled the height of the summit and col to be estimated when compared to the lack of detail on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps.
Therefore with an estimated summit height of c 412m based on an uppermost 410m ring contour on OS Maps and an estimated col height of c 392m, based on col contouring on OS Maps between 390m – 395m, this hill is now listed with c 20m of drop, which is sufficient for it to be classified as a 400m Sub-Four.
The full details for the hill are:
Cardinal Hill: Axe Edge
Summit Height: c 412m
Name: Dow Low
OS 1:50,000 map: 119
Summit Grid Reference: SK 100 675
Drop: c 20m
