A wildfire in northern Colorado has increased to 11 square miles, and firefighters are trying to keep it from spreading to ranches and homes to the south and east near the Colorado-Wyoming line.

Routt National Forest spokesman Aaron Voos says more firefighters are on the line Thursday. Voos says there are a number of fires that have broken out across the West, and fire commanders are competing for resources.

Voos says a number of campers have been evacuated from the national forest, but no other evacuations have been ordered.
