Pemigewasset Wilderness Food Storage Requirement
Effective May 1st, 2026, all overnight campers in the Pemigewasset Wilderness must store all food, food containers, scented items (such as soap, lip balm, and toothpaste) and refuse in a cylindrical, hard-sided, non-pliable Interagency Grizzly Bear Committee (IGBC) certified bear resistant canister. Alternative methods, including bear hangs, for storing food and bear attractants in the Pemigewasset Wilderness will no longer be permitted as they have proven to be less effective than canisters. The only exceptions are the bear resistant food boxes located at the Thirteen Falls Tent Site.
