A YOUNG BEAVER HOUSE 
A new or recently built beaver house always has steep sides and is generally as high as it is wide. 
If located out in a pond or lake there is often as much or more of the house material under water 
as there is above 
A WELL-BUILT BEAVER, HOUSE 
This house in the middle of a pond was being built up and thickened for winter use. Mud 
and sticks were piled on the sides and top every night, and green wood cached in the water 
near the house for winter food. Early mornings and late evenings the beavers Were often 
seen at work on it
