This is one of the hot spots for looking for Wolves in the Yellowstone area.  This group is the Slough Creek Wolf Pack (well, this is just a photograph of some trees and reflections...but I am referring to the group of wolves who inhabit this area) pushed out the Druid pack that used to inhabit the Lamaar Valley.  They are now called Agate.

This baby moose and his momma were being hounded by folks...I really thought that someone was going to get hurt.  Fortunately, no one was injured.
