S" Photo by George Shiras, 3rd BIG BULL MOOSE AND TWO CALVES AT A BEAVER POND IN THE UPPER YELLOWSTONE VALLEY In the background is one of the heavy pine forests which harbor the moose during the winter, whilethe adjacent willow thickets provide nourishing bark after the coming of the deep snows, just as the warm waters of the numerous beaver pondsafford the choicest of summer food. The variegated horn growth is shown here, where in one bull are two of the three prevailing types, the left antler being round and long, like that of an elk's, while the right one is heavy and broadly palmated. This great collection of moose live continuously inthe valley, seldom ascending any of the hills more than 50 feet, so thoroughly satisfied are they with their yearly surroundings. It is forthis reason that they solong escaped observation by government scouts.
