The grizzlies in our grizzly bear viewing area tend to avoid eye contact as it is seen as a challenge. In this case the eye contact on the part of the bear is a challenge in that we were to close. We were in the skiff on the river and this grizzly appeared suddenly out of the bush onto the grassy estuary and started walking toward the boat. It took a few minutes for us to drift down the river past the bear as were unable to go up river because of the low tide. The bear paused as we went by and we made sure not to stare directly at the bear.
