I caught this tiny cub out of the corner of my eye and had to get closer to get a picture. Cubs almost always climb up a tree when they feel threatened and that was the first thing it did when it noticed me approaching. Never saw mama, but all the people I know who work with bears claim that black bear mothers will hide from humans, even if they stand between them and their cubs. The so-called aggressive black bear is a popular myth, although it holds true in places like Yosemite. A wild black bear will generally take all measures to avoid you.
