I ran across this photo of the Track fire that was posted to TwitPic by the Colorado Department of Transportation on June 14, 2011. The fire, which we covered here, started on June 12, 2011 and burned over 27,000 acres on both sides of Interstate 25 at the Colorado/New Mexico state line. It was contained on June 29.
Compare the above photo with the one below taken on October 17 on Interstate 17 in Colorado at Loveland Pass, also posted on TwitPic by the Colorado DOT.
