Smoke and heat from the massive wildfire created "fire clouds" (pyrocumulus clouds) over the Bootleg Fire in southern Oregon - dangerous columns of smoke and ash that can reach up to 30,000 feet and are visible for more than 100 miles away. Authorities put these clouds at the top of the list of the extreme fire behavior they saw on the largest wildfire burning in the U.S. This July 14 photo was taken with a drone provided by the Bootleg Fire Incident Command.

PORTLAND - Smoke and heat from a massive wildfire in southeastern Oregon created giant "fire clouds" over the blaze - dangerous columns of smoke and ash that can reach up to 6 miles in the sky and are visible from more than 100 miles away.
