Grasshopper is now learning less is more; above 2 figs. much better than Post No. 56.

Now I'm not rivet counting mine spoil heap shapes but :

Hard rock waste dumps are normally fan shaped or elongated rectangular - as the tipping track is advanced across a flat topped pile and using end or side tipping wagons. Conical heaps are typical of soft rock coal mines where a conveyor or aerial ropeway dumps stuff at the apex of a 360 deg cone.

Maybe I should get out more ? (I would if I could)
