MPR’s Steve Monroe reports on numerous towers toppled in southwestern Minnesota by winter storms, including the KRSW 700 ft broadcast tower. A combination of freezing rain and high winds were too much for numerous radio and TV towers in Minnesota, Iowa, and South Dakota.
While freezing rain was the issue in southern part of state, the storms from March 23-24, and March 26-29, 1975, brought blizzards to northern Minnesota. 100 mph winds and 20 ft waves on Lake Superior dumped a foot of snow and created zero visibility near Duluth.
