Eventually he ended up in the notch between Haystack Butte and the Garden Wall ridge, still digging up hornet's nests. At this point, we didn't want to make him feel like we were total groupies and we had to get over Swiftcurrent Pass and down to Many Glacier, so we left our cordial bear to perform for the large crowd that had gathered. If only all grizzly bear encounters were like this!
I hesitated to post this, as it is obvious that one should never TRY to get this close to a grizzly bear. This guy however, got close to us. After he crossed the trail going uphill, we tried to put some distance between him and us by going away from him, north on the trail, but he ended up following us northward. As you can see from the last photo, we made sure we weren't the closest hikers to the bear!
