These photos were taken by Dan & Arlette Schweitzer, of Keystone, South Dakota on October 9, 2008. The photos are of an adult female cougar and apparently her 2 nearly grown cubs. They were feeding on a white-tailed deer killed by the cougars near the Schweitzer property just west of Hayward, South Dakota, and about 4 miles east of Keystone. The adult female has a yellow ear tag, and cougar researcher, Brian Jansen of South Dakota State University, believes she was a study animal that had recently slipped her collar. The pictures are not of any cougars in Buffalo or Trempealeau Counties in WI, or any location in northern Minnesota.
