GRANTSBURG, Wis. (AP) – Department of Natural Resources crews continued to secure fire lines and put out any hot spots after a planned fire unexpectedly spread in Burnett County.  Crews contained the fire near Grantsburg Tuesday afternoon, but not before it consumed 600 acres beyond a planned burn area of about 500 acres. DNR crews worked the lines and hot spots Wednesday.  The prescribed burns are routinely used to manage marsh and grasslands for wildlife habitat. No structures were damaged and no one was hurt.
     Grantsburg is about 70 miles northeast of Minneapolis.
