2012 - A Highline Adventure, Cloquet, MN

Hanging over the St. Louis River in the state forest near Cloquet, MN, there's a 1" steel highline conecting the two river banks. No one knows why it's there. No one knows when it was built. Even the MN DNR is not sure of its history.

Mounted aboard the carriage that rides the line is a geocache named Highline (GC3EHXK) by EskoClimber. Today, in an attempt to practice safety in numbers, we held a geocaching meet-and-greet event in order to complete the 4.5/5 rated geocache. About twenty of us gathered for the The Great Geocaching Circus - A Highline Adventure (GC4023F) and while I was the defacto chosen one to ride the wire, I think it is safe to say that all of the event attendees had a great time.

In order to ride the wire out to the carriage, I had built a zipline trolley out of 1/4" plate steel. Two plates were held in place with four 1/2" bolts. Two steel idler pulleys were mounted between the plates using 1/2" class 8 bolts serving as a shaft. The idea is that for safety, the trolley gets mounted onto the wire. Therefore, if any single piece failed, the entire trolley should stay mounted on the wire. The device worked more or less as planned. Though, one small design change would have significantly lessened the amount of work required.
