The cub scampers away, and the mom hops up on the trunk of the fallen tree and walks away, sneering back over her shoulder. I fumble with camera settings, hoping to get a shot before she gets too far, when she turns around to have a word with me. I get one picture as she growls and advances toward me. The growl sounds like that of a horse expelling air through its jowls, but much more effective at communicating a threat. I backpedal as fast as I can without turning to run, still trying to click pictures.
