KPLO TV, KPLO FM Medicine Butte – near Reliance SD.
A 711′ tower fell, apparently due to ice buildup. The base of the tower was at was 400’ above average terrain.
There was heavy ice on the tower. The technician in the area reported he couldn’t see the top of the tower for days.
The fallen tower was built around 1958, but rebuilt and strengthened in the 90s with a major rebuild. Then it was recently strengthened again when digital antennas went on.
On a couple of the pictures you can see the ice still on the guy wires. This photo was after a day of melting and you would think the collapse would have knocked the ice off.
