It was just an idea, connecting "rivers", possible net, and the "curtains of mountains". Hardly this place is the low edge of a mountain (where there often are sort of "curtains"). Isn't it funny, that mountains are complicated things, hard to understand, once been living. Englishmen could go and sound and probe the cone (with the same equipment, that they used in Janakkala & in Stonehenge). Contents... if that is not a mushroom, then it's some egg- or larva-pack. Or both).

Seems a bit like river sucking... as in the picture above, too.
