This curious piece of industrial junk is very close to the so-called "kitchen area" for the backcountry campsite. We heard a rumor that it was debris from oil drilling in the area. It looked like a heat exchanger of some kind, and it was very heavy. Whomever brought it in, took a lot of effort. It's a great landmark for boaters to find the backcountry camp.
No motors are permitted on Kintla Lake anymore, which really helps maintain the quiet.
