Duskrats! They've been eating the duskrats! Those little buggers only come from one place, a cave against the cliff-face to the east. Find a path up to the northeast and look for an opening under the waterfall.
The duskrats there are either getting into something nasty or someone's intentionally spreading some agent through them - in either case, just bring me back several samples of the stuff!
