Deep snow and predators kill many calves at this time. The moose leave the mountains when the snow gets belly deep in the mountains. They go to the rivers where the winter chinook has caused the snow on the river to be far less deep. They live individually on islands and sandbars unless there are many wolves, when they will get in groups as big as 15 moose on an island. Predators kill many calves during this time.
Wolves surround a moose, keeping it from eating until it is too weak to fight well.
Again, during crust time the moose are in great danger. Moose typically sleep in a certain type of place. A moose is a ruminant. Find and describe the four stomachs. Identify the traditional names for each.
