A hog-nosed skunk is seen near a campsite in the Grand Canyon 

A hog-nosed skunk is seen near a campsite in the Grand Canyon in Arizona in this photo made on Aug. 4, 2012.  A river guide familiar with animals in the Canyon spotted the skunk - not known to the area - and now park officials are deciding whether to add it to the list of species found in the park or ignore it as just another animal passing through.
