BWCA Jack Lake Mine

Have you heard of the Jack Lake Mine? I hadn’t either until my dad showed me an article about it in an issue of the Boundary Waters Journal. This was an intriguing adventure! After doing a bit more research, the decision was made. Jack Lake was to be our next excursion into the BWCA.

This “mine” was actually a test pit for iron ore. When the test samples came back lacking, the mine was abandoned. What was left behind is a sizable whole and numerous artifacts. I’m not sure how aged items must be to gain the title of “artifact” but these sure felt like artifacts to me. These are still strewn about the entrance of the cave. Thankfully visitors have been respectful and left the area as it is. It looks like the miners were simply on a lunch break, a long lunch break.

Finding the Mine

I wasn’t sure about finding this mine. The resources I had found weren’t too clear. It all seemed too simple, I was expecting this to be a hard to find and overgrown trail head lost in time with downed trees and brush. Or that it would be so long that we wouldn’t be sure it was the right trail at all, it wasn’t marked on any map I could find, so maybe it wasn’t really there. None of these things happened. Finding the mine really is that easy, I over thought it. Don’t overthink this one. It’s right there!

Entering from Baker Lake Entry Point #39 is an easy access point. Whether you’re traveling for an extended trip or for the day, this is a very doable adventure. It’s basically a straight shot. Baker lake is a quick dip in the water then it’s already portage time to Peterson Lake. Peterson, though longer than Baker, still isn’t that large of a lake. The paddle went quick, Peterson leads right into Kelly. With higher water, we skipped the 3 rod portage and opted to traverse the flowing water. It was a breeze. Kelly Lake is longer but a beautiful paddle up river with many beaver lodges to view along the way. You’ll know your at the next portage when you find yourself at some breathtaking rapids. The portage is at a rocky edge to the left of the rapids. Take the 69 rod portage to Jack Lake. Now here is were I over thought it. At end of this portage there is a small foot path to your left as you are looking at Jack Lake. That’s it, it’s right there. So obvious. The path is about 50 feet long and you’re there, can’t miss it.

Note: There is good fishing at the rapids on the north end of Kelly and in the sheltered entrance to Jack Lake.

Tools and Artifacts

Approaching the mine off the trail, you’ll be greeted with pieces of the past. Chains, rusted metal and tools are scattered about. At first glance, this seems like someone left a dirty campsite and it needs to be cleaned up and taken care of. Please leave these things as you found them. Treat it like a “Leave No Trace” situation. This little bit of history is a wonder for others to find.

Watch Your Step

I know this cave is intriguing and you’ll want to dive right in, but hold your horses. There are slippery rocks, ice on the cave floor, even the walls are damp and slippery in places. Proceed with caution, be sure to have steady footing and maybe hold onto that slippery wall. Take your time, the cave isn’t going anywhere anytime soon.

Ice in the rear of the cave is a marvel in the heat of summer. Even in early June, with the heat we experienced, I was surprised to find the thick cold slab. I would be curious to see if the ice remained by the end of August. I suppose that means another trip is in order. Yay!

It’s quite dark near the back of the mine, bring a flashlight or headlamp along. You’ll not want to miss any details hiding in the darkness. Speaking of things hiding in the darkness, that brings me to my next point… Wildlife.

Wildlife

As we all know, bugs in the Boundary Waters are horrendous and it can sometimes be muggy and hot in the summer months. The cave is an amazing escape from both of these things! The animals are aware of this too. On our first visit to the cave, we found a moose track in the ice. It was so unexpected, it had warn it’s way into the still melting ice.

Our second trip to the cave the following day was a bit more alarming. So much so that we did not attempt to enter the cave at all. At the mouth of the cave was a rather fresh bear track leading into the mine. So cool! But the problem was, we couldn’t find the tracks leading out. There is no other way into or out of this mine. That bear was still in there somewhere. We calmly vacated the area and decided to fish in the little bay leading into Jack Lake instead. A fruitful choice as my dad caught a nice bass off a bed near the small rapids leading into the larger part of the lake.

The Jack Lake mine is an easy addition to this already exciting area of canoe wilderness. It’s thrilling additions like these that can add a twist to an already exemplary trip. Especially when you have your children along. Having kids off on these grand adventures and treasure hunts creates memories that will last a lifetime and a sense of adventure that will carry on into adulthood.
