Firefighters say they could have the Waldo Canyon Fire in Colorado contained by Sunday. The historic blaze destroyed nearly 350 homes and burned more than 28 square miles.
Rain and cooler temperatures are giving firefighters a chance to gain ground and forecasters say more is on the way.
Colorado officials called off Fourth of July firework displays in many parts of the state. Law enforcement also warned of hefty fines for people caught violating personal fireworks bans.
Many residents, still reeling from the fires' devastation, joined in policing the ban.
One homemade sign in Colorado Springs read, "FAIR WARNING: Anyone using or allowing use of fireworks in this neighborhood will be dealt with harshly! And that doesn't mean just by the police!"
Meanwhile, wildfires continue to blaze in Montana, Wyoming, and Utah
Much of the Midwest is also still experiencing drought-like conditions. Cities and towns in at least 20 states banned fireworks on the Fourth because even the smallest spark could set off another wildfire.
