This was our planned exit day. First trip with the 3 and 6 year olds, camped on Pierz Lake from East Bearskin Entry. After a warm, humid, night we woke up at 7:00 with the low, intermittent rumbling of very distant but big thunder. Almost questioning if we were even hearing it at all. In a reference to '93 Jurassic Park, my wife looked at me and said, "Maybe that's the power trying to come back on..." We shared a good laugh, but then started packing the kids up. The sky was mostly clear with maybe some high clouds, but with a limited view to the west while standing at the edge of the lake we could see the dark edge on the horizon. We took down the tent and gathered packs under the tarp as the thunder grew steadily louder, then ate breakfast down by the lake as we watched the dark front advance toward us.
It almost seemed to break up as it grew closer into a spectacular striated cloud pattern- almost like a rainbow of grey colors. For a moment I thought it might resolve before it hit us, but the sky did reform into a classic wall cloud: an advancing black band with a sharp lower edge trailing a curtain of deep greenish grey- flashing with the lightning contained within. That is always an ominous sight to see when the air around you is perfectly still and peaceful. I quickly made sure that camp was buttoned down and ready. The first raindrops fell, and in the time it took us to walk back to the tarp we turned around to see the lake churning with windblown whitecaps; and on this small lake with only 100yds or so of upwind reach from the west. Storms like this always seem to jump upon you faster then you expect.
The tarp was a 12x10 I sewed myself from 1.1oz silpoly that had already proven itself when a storm blew at my exposed campsite on Ramshead lake this past May.
I love the art of the tarp hang, and at this camp I feel like I had achieved the perfect tarp: high enough to stand at points, but still blocking any windblown rain, angled enough on both sides to prevent water pooling on top but still giving us a good view of the lake, and placed where it covered the best "tabletop rock" in camp and still shed water in directions that wouldn't run rivers beneath the tarp. Our site had enough surrounding trees to be fairly protected from wind; and perhaps the storm did loose some energy before crossing the gunflint as I witnessed a couple broken branches but no down trees (plenty of down trees later along the highway from two harbors to moose lake). The terrain and trees were such that I felt fairly safe from any ground lightning.
Just after the gust-front came the dark. It hit us at 8:50 am, after the sun had been up for three hours, but it got much darker than the kids had seen at any time during this near-solstice trip. An f2.6 lens wasn't fast enough to avoid blur and forced flash photos outdoors during daytime. It blended in with the lightning just fine. The kids were awestruck by the storm. Maybe a little scared, but their parents stayed calm enough that they didn't get any cues that there was anything to be frightened of. We drank coffee and cocoa and counted seconds between lightning strikes and thunder reports. We stayed in our 12x10 plot of dry pine needles and played tic-tac-toe beneath the tarp as we watched the blowing front subside into a steady rain with regular thunder.
It was about two hours total before the thunder again became a very distant and intermittent low rumble. We took down the tarp around 11:00, loaded the canoe and set off towards the entry, without further rain but with a stiff (now east) wind at our backs.
Not the worst storm I've weathered, but it sounds like it was more intense to the west of us an hour or so earlier.

Muddyfeet, how about starting a new thread and teching the rest of us "the art of the tarp hang"?

We rode this storm out on Lake 3 that morning. This pic shows us holding down the leading edge of our tarp, but this wasn't the worst of it...that was yet to come. We heard later on that a reporting station near lake 1 recorded a 90 MPH gust. Trees across the channel were falling down. I told my crew that if we were home, you'd be hiding in your basement, but out here you get to experience this raw natural event first hand. It was pretty exciting. You don't talk about the days of blue skies and sunshine, you remember and talk about these storms like they are badges of honor to brag about.

I was on Lake 3 the day before and we pulled out early due to the forecast. Kids would have been terrified and I want them to come back some time.

Another notch on the belt in terms of what you can handle. I appreciate these moments because it gives you confidence and a sense of pride knowing you've experienced some of the worst weather you can encounter on one of these trips.
