You've probably all seen the "big green" in Tim Treadwell’s documentaries on TV. This was taken at the South end of the big green. Our boat was anchored a few miles away and we were dropped off on shore by a skiff. The skiff then returned to the main boat. We have radio contact if we need them, but they are about an hour away.
Our bear guide has us set up our gear in certain areas where he thinks the bears will come. Several bears are in sight, just not close. After some time (sometimes 15 minutes, sometimes 2 hours, sometimes not at all) the bears feed our direction and sometimes come real close. We are unarmed, no bear spray - just one bear flare (similar to a road flare). We can't run or retreat, we just have to sit it out and take pictures until our bear guide tells us otherwise.
We sit on low stools and have the tripods set up really low (maybe 36 inches?). No sudden movements.. staying close together (3 people).
