(Mitchell, OR)  --  The Klamath County Museum says the Mitchell Monument has been spared from the Bootleg Fire burning in southern Oregon.  Officials say firefighters wrapped the monument with flame retardant and insulating blankets to protect it from the blaze earlier this week.  The Mitchell Monument was built in 1950 to mark the site where a Japanese balloon bomb from World War Two killed six Klamath County residents in 1945.  The Bootleg Fire has now scorched over 395-thousand acres and remains the largest wildfire currently burning in the U.S.
