This is a look at a Croatian island with two different karst landscapes. Comparing the two is an interesting look at the influences on karst development.

This isn’t strictly about karst - it discusses limestone erosion, but is a much broader discussion on landscape evolution, with a significant focus on Ireland.
Optional additional reading
If it looks like karst…is it karst? Or does it have to be formed like karst?
