I’m gonna hazard a guess that a spring grizzly bear guarding a carcass is likely to charge with little preamble or warning.
They are a little cranky this time if after not eating for 4 months. They tend to wander closer to people down low looking for food as the snow melts. Lots of snacks from winter die-off coming out of freezer.
