Compass rose two adjacent cardinal directions. For example, North-by-east (NbE) is one quarter wind from North towards East, Northeast-by-north (NEbN) is one quarter wind from Northeast toward North. Naming all 32 points on the rose is called "boxing the compass". The 32-point rose has the uncomfortable number of 11° between points, but is easily found by halving divisions and may have been easier for those not using a 360° circle. Using gradians, of which there are 400 in a circle, the sixteen-point rose will have twenty-five gradians per point. Linguistic anthropological studies have shown that most human communities have four points of
Swirl How spot height for Swirl How, although it is included on the 1:50,000 and the height is stated as 802m. Birkett and Wainwright also quote 2,630 ft (802 m) whilst Richards and the British Mountaineering Council 1:40,000 map quote 2,637 ft. (804 m) Swirl How sends out ridges to the four points of the compass, each leading to further fells. Consequently, it also feeds the headwaters of four valleys. The ridge northward to Great Carrs is named Top of Broad Slack, Broad Slack being a ferociously steep grass slope climbing out of the Greenburn valley between neighbouring crags. The ridge is
