Demolition
The demolition of the LORAN-C tower took place from November 8th, 2011 to November, 10th 2011. On the first day, all but three guy wires were removed – and an extra guy wire was added for temporary stability.

On the second day all oil was removed from the base insulator and safely removed off site. The guy wires on the first level were removed, along with three guys from levels two and three that were on 40 ft. slings to reduce the tension in the guys. The site was also secured at this point. All doors to the facility where locked in preparation for a controlled demolition.

On the last day the appropriate signage and perimeter were created to ensure that no unauthorized personal were on site. When this measure of safety was established the top level guys were cut, finally the middle anchoring guy was cut – allowing the tower to safely drop without incident.
