Thirsty Bear Vault update

Sarah at BearVault was kind enough to respond to our recent questions about water getting into the BearVault during a storm.  Here's what she wrote:

There is a small lip on the BearVault housing which prevents a bear’s claw or tooth from getting under the lid during an attack.  If the BearVault is almost perfectly upright then during a rain this lip can allow a small “moat” of water to form at the top of the housing.  If the storm then passes during the night, the atmospheric pressure gets higher and this forces the water in the “moat” up the threads and into the housing.

To prevent this, just tilt the unit slightly during the night so that the water cannot accumulate in that “moat” if it rains- it’s that simple.
