I was at the Brule Lake put-in point getting ready to launch a 3-day family
canoe trip with my wife and 7-year old daughter when the storm hit on
Sunday afternoon. It was warm, cloudy, and still, and the mosquitoes were
active, as we loaded our ton of stuff- everything from the 14-pound tent
and the cooler of fresh food to the teddy bears and camera gear. We had
just chatted with some people who had come in, when I looked up at the sky
again and saw the low, ominous green swirling squall line approaching. Oh
oh, I got the others back in to the car, and was covering the canoe with a
tarp as the winds hit with sheets of blowing rain. The tarp became mostly
unmanageable, and the canoe started to fill with water. I pretty much
always use waterproof kayak bags for canoeing, so the gear was safe, and I
grabbed one of the camera bags and retreated to the car. It was difficult
to walk and the car was swaying in the wind.

1 to 1 1/2 foot waves had built up in the small bay as horizontal blasts of
rain obscured all but the immediate scene. Lightning was blasting down all
over and the trees were rocking, but we were in a bit of a low area, away
from the larger stands of older trees. The car windows began to fog up and
I lost sight of the canoe, so I staggered out to find that the wind had
blown the loaded canoe with four inches of water in it- perhaps 300 pounds-
about 50 feet across the gravel boat ramp. Since I was already soaked and
most of the lightning had moved on, I just stayed out to baby sit the
canoe, pumping it out with the kayak bilge pump I had along. Eventually the
wind and rain eased up, and I got the canoe emptied and checked for damage-
only some long scratches and a few gel coat cracks- thank goodness for
expedition Kevlar layups. 

Walking around, we found dozens of downed trees and a toppled information
sign. Two rangers from a nearby cabin came by and said there was another
storm cell moving into the region. advising us not to venture out for
awhile. At that time, they, and we, did not know how thoroughly blocked the
access road to the south was. After hanging out a bit, a couple returned to
the landing by canoe, seeking help. The man had gotten clobbered in the
head by a falling tree at their campsite, and had some memory loss. We
helped them load what gear they were able to recover, and the woman was
able to drive, so I gave her directions to the Grand Marais hospital, and
they took off, not knowing that the road was blocked.

Soon, a party of three guys returned- they had been blown into the shore at
the east end of the lake, lost some gear, and their solo canoe had been
partially crushed. The portage trail they were approaching had been
completely blocked. A third party returned from a camp on the lake and had
lost a tent and some gear, hopelessly buried by a huge downed white pine. A
fourth group, of fishermen, showed up with the first load of their stuff,
after their site was demolished, but no one was hurt. Three hours after the
storm first hit, the whine of chain saws got louder, and the first vehicle
made it in from the south with news of all the surrounding devastation. 

After the weather settled down for a while, we elected to go out to try to
find a campsite. After talking to several more canoeing parties in the
area, we headed for a site on an island I knew was relatively free of large
trees. The lake- the highest elevation large lake in Minnesota- was full
flating debris. After setting up, I had to use the trusty Swen-saw to cut
through about five downed trees to reach the campsite biffy. My daughter
thought it was all in good fun as she hunted for water bugs and had hot
chocolate. After dark, however, several lines of thunderstorms moved
through all night, with a constant barrage of lightning and about four
inches of rain. In the foggy, drizzly morning, we decided enough was
enough, and to call it quits. On the drive out to Hwy. 61, there were over
a hundred clumps of downed trees, each with a narrow chain saw cutout
allowing the width of one vehicle through. 

The storm was worst in a thirty-mile long area from the Ely area over to
the central Gunflint. The evening TV news showed areas of completely
flattened trees caused by rapid downbursts of 120 mph winds, in the
estimation of the meteorologists. 80-mph winds were common over a wide
area. Helicopters are searching for more remote parties that may be in need
of help. Many campsites and entry points will probably be closed for some
time. I would guess that volunteer help may be needed for some of the work
that lies ahead.

I have only seen a storm of similar intensity once before, on Lake
Superior, with similar winds that sheer off the tops of building waves and
blast horizontally with a fire-hose like power that makes anything but
hunkering down for dear life impossible. Lightning is the major hazard-
stay away from tall trees and other large objects if possible- which
unfortunately means going to the lowest, wettest, buggiest spots. Falling
trees are a problem in the BWCA  where the soil is a thin veneer over
bedrock and tree roots are shallow, and the forest is aging. Keep that in
mind when seeking shelter or choosing a campsite. Above all, be aware of
the dangerous stages of thunderstorm and squall line development and the
resulting cloud types, and be prepared to get off the water and seek
shelter well before it's too late. Nature can be relentless, and your only
real line of defense is to always anticipate the worst and be ready to take
protective action.
