Bear Vaults are allowed in the High Peaks, just not recommended. Only one bear has figured out how to open them, Yellow-Yellow. The DEC has, reasonably, decided not to change regulations for a single bear in North America. Marcy dam, and Colden lake is her primary circuit...at least the last few years.
For any who would like to use the BV's, a simple wood screw, hot melted into the lid and case on the oposite side of the catch, will solve the problem. According to a reported instance, she presses the catch with her teeth, twisting with her head. The positive lock of the screw defeats this behavior. Hopefully, after a few times, she will no longer bother.
Anyway, the Berikade or Garcia are recommended. Both require an extra tool to open as does the BV after the modification.
