Tree breaks
Tree breaks or twists are defined as when the tops of various species of trees (usually pines or firs) are snapped or twisted off. Often the trees are 4" dbh or larger, and the broken pieces are apparently left to hang in a precise direction. Proponents view tree twists or breaks as being consistent with the behavior of other great apes (i.e., displays) and with behavior reported by Native Americans (e.g., the Nelchina who note that tree twists are a territorial sign of the sasquatch) and some witness reports. Opponents view tree twists as an ambiguous form of evidence at best due to the ability of nature to create similar examples in abundance. Some researchers argue that tree breaks or twists should only be considered as possibly formed by sasquatch activity when accompanied by corroborating evidence.
