This is a square of the Isle of Walney, which has been part of Barrow in Furness since the late 19C. In 1873 it was “nominally a subdivision of Hawcoat”, a division of Dalton Township in Dalton parish. It lies on Triassic mudstone.
The 1873 map is 6in / mile, on the 'old-maps' site; the 1891 map is 1:2500, on a Digital Archives CD. The 1in. Map of 1965 is also referred to occasionally, and the 'modern map' is Explorer Sheet OL6.
The roads that form the framework in this square were mostly there in 1873. They meet at csq 85 -
SD178685, Sandy Gap Lane going SW to the beach, Black Butts Lane, now a housing estate road, to the SE and Moor Tarn Lane to the NW. The latter becomes Mill Lane at csq 69 -
SD176689, but the site of the mill is not shown; it was a windmill, and the licence allowing its erection is dated 1558. Central Drive, continuing Sandy Gap Lane eastwards, is modern (but before 1965). The footpath along the coast northwards from Sandy gap is also shown on the 1873 map.
Between the footpath, Sandy Gap Lane and Mill Lane there were some enclosures called Moor Lots, which I take to mean plots of common land allotted to local landowners by an enclosure commissioner. The 1873 map shows a building called 'Moor', ruined at csq 56 -
SD175686. This area is now a golf course, so I doubt there is any trace left of the ruin, although the modern map shows traces of the field boundaries. The sand pit on the 1891 map (gravel on the 1873 map) at csq 45 -
SD174685 is on the modern map, perhaps providing a bunker. At csq 68 - SD176688was Moor Tarn (its site in the middle of the present road), and a spring, stream and culvert. The building at Beacon Brow is modern; there was a trig. Point here, but no sign of a beacon. Finally, the school at csq 84 -
SD178684 was built here in 1951. It is a comprehensive secondary school.
