What does the freezing Rocky Mountain water do to beaver pelts?

Freezing Rocky Mountain water causes beaver pelts to become stiff and brittle. The cold temperatures can lead to the pelts losing their natural oils, which are essential for maintaining their softness and waterproof qualities. As a result, untreated pelts exposed to freezing conditions may become less desirable for fur trade, impacting their value and usability. Proper handling and storage are essential to preserve the quality of the pelts in such harsh conditions.
