The thaw of the previous week had left a nice crust on top of the snow
pack. Because of this, many animals, including us, could walk onto of the snow. We found we only had to
wear snowshoes about half of the time. However, Moose being very heavy, punch through this crust,
leaving these "potholes" in the snow.
Notice the dumbbell shape of the tracks. The moose's foot is larger than its lower leg. When the leg
enters the snow it leaves a large hole. As the moose's body moves forward its lower leg cuts a narrower
channel through the snow. Then when the moose's leg lifts out of the hole, it leaves at an angle going
forward and once again the foot makes a bigger hole. |
