I have a guide friend who was camped on Kekekabic on the west end, and another who was camped on Eddy Lake.  As I remember, it was pretty rough stuff, but I'll try to get more details.

I was on Gibson Lake when I saw the approaching storm.  Figured it was a similar large thunderstorm blowing up as had the previous day at about the same time.  Pushed my crew to cross Gibson and take the Cattyman Falls portage.  At the end of the portage, we stopped for lunch, because there was no way I was going to be on Cattyman in a thunderstorm.

The Boy Scouts teach that in a thunderstorm, your group needs to spread out, as lightning can arc from person to person.  So as the lightning gets closer, I send everyone out into the woods.  All was fine until the trees started really cracking.  Thankfully, I got everyone huddled up together on the rocky portage as the trees started crashing down.  It certainly felt like the entire forest was coming down.

One thing I will never forget, but I seldom hear anyone esle echo, is the intense thunderstorm that night.  We were camped on Ima, and I remember that storm keeping me up for at least an hour of almost nonstop flash-boom nearby strikes with other trees falling in the night.  Did a lot of praying that night.
