A "lebnakan" or a "lubnakan" is where carabaos dip in mud and water. There are a number of reasons why they do this. They do it to cool down. The mud also helps protect them from intensive heat and from pests like flies.
Other Cordilleran words for it: tabbakan, lubnaan, tablakan, pitlawan.
We passed this "lebnakan" somewhere in Mallango, Tinglayan, Kalinga during the Lumin-awa Trek.
