River Lune the West Coast Main Railway Line run. Below the gorge, the valley broadens out into Lonsdale. Bridges over the Lune include the Devil's Bridge near Kirkby Lonsdale and the Lune Millennium Bridge in Lancaster. At Caton, about upstream from Lancaster, there is a cluster of three bridges (one stone road bridge and two disused iron rail bridges now used as foot/cyclepaths) at the "Crook o' Lune". Here in a 180-degree right-hand bend the Lune turns back on itself; this is followed by a 90-degree left-hand bend forming the shape of a shepherd's crook and creating a beauty spot which was
Spherical lune example, a regular hosotope {2,p,q} has digon faces, {2}, where its vertex figure is a spherical platonic solid, {p,q}. Each vertex of {p,q} defines an edge in the hosotope and adjacent pairs of those edges define lune faces. Or more specifically, the regular hosotope {2,4,3}, has 2 vertices, 8 180° arc edges in a cube, {4,3}, vertex figure between the two vertices, 12 lune faces, {2}, between pairs of adjacent edges, and 6 hosohedral cells, {2,p}. Spherical lune In spherical geometry, a spherical lune is an area on a sphere bounded by two half great circles which meet at antipodal
