startling expressions of possible environmental degradation have been found in Minnesota, us . Deformed frogs have been seen in more than 100 sites in 54 of Minnesota's counties.

Reports of deformed frogs have also poured in from other parts of the state.

The deformed frogs were first discovered by school children during a field trip in south-central Minnesota. The amphibians were either found with missing or withered hind legs or extra limbs.
