Wildlife was not easy to spot considering the huge expanses of land we were traveling through but it was fun when we did see it. This moose and two calves came down to the river to grab a quick drink of water one evening. They could really move along when they wanted to... The moose (Alces alces) is the world's largest member of the deer family. The Alaska race (Alces alces gigas) is the largest of all the moose.
