@Biotop, glad that things worked out safely for all concerned. Black bears are typically not as aggressive and hence not as dangerous as brown bears (aka “grizzlies”) but AIUI colorations do vary, and after all, a bear is a bear, and always a potential danger.
In a previous post, I recounted my own close encounter with a Mama bear and two cubs . Sadly, it did not end well for Mama but the two cubs were found and relocated well north of the populated areas of the park. As mentioned in that post, although we were somewhat concerned for our safety, it was nothing compared to what happened to the couple camping on the other side of the bay, who were apparently not accustomed to basic camping practices and had Mama and her cubs actually invade their tent!
