Totally by chance, while working further with John VanSickle's height_field 
patchwork macro, I came across this landscape. I called it Drifting Over The 
Traps.

For those who wonder what Traps are: this refers to the Large Igneous 
Provinces, of which the Siberian Traps at the Permian-Triassic boundary, and 
The Deccan Traps at the Cretaceous-Tertiary boundary are the most famous for 
alledgedly being responsible for major global biological extinction events.

I shall probably work further on this, but I thought I would already share 
this image with you.

Hey Thomas,

Interesting landscape. I bet 'The Traps' have some great potential for 
good mineral hunting. That's assuming they harbor pegmatite dikes. If 
the composition is mainly basaltic, then there's a good chance of 
finding some zeolites. I've always wanted to find some apophyllite, 
which is found with zeolitic minerals.

I haven't forgotten about the weathered rocks tutorial I've been 
promising for months. I'm just not sure how to start new pages on the 
POV Wiki yet...

The traps are basaltic indeed. I rapidly googled and found this:

or this one:

How about the Karoo, Sam? Smaller than the traps in Siberia or India, but 
still a vast igneous province.

Would be nice... :-)
