Nahanni: karstlands

The Nahanni karstlands are one of the features that make the South Nahanni Watershed a globally significant natural area. These fascinating limestone formations are full of caves, sinkholes, alvars, underground rivers and streams, springs and sealed lakes.

Water moves swiftly through the "secret landscape" of karst. Rivers running across the surface suddenly drop below ground, resurfacing great distances away in springs or seeps.

From above, the karstlands appear to be outside the South Nahanni Watershed, but world renowned expert, Dr. Derek Ford, has determined that the Nahanni karstlands feed water directly into the South Nahanni River. That's why he's calling for the inclusion of the entire karstlands area in an expanded park.
