Karst is an area of land underlain
by limestone that is honeycombed with
sinkholes, underground streams,
and caves.
Limestone, a soluble rock, easily develops cracks, or joints.
As rainwater seeps through the cracks, it
slowly dissolves the limestone.
Gradually, underground streams
and caves form in the rock, and sinkholes develop at the surface.
The processes that form karst topography occur underground.
In areas where weathering and erosion have worn away the land
above, the limestone ridges, caves, and
sinkholes that are characteristic of
a karst region are visible.
Even where rain is plentiful, some karst looks dry and barren. In
these areas, rainwater seeps through a thin layer of soil into the limestone and
disappears.
The word "karst" comes from the Karst region of the former
Yugoslavia, which is rugged and lined with caves.
So... there are 5 logos I like... the five above this line...
I would, however, like to play with the actual font of the word, and
make it more angular than the ones here (more like the top two)...
The logos below here I'm not too keen on...
