Dozens of wildfires burn across California

Dozens of wildfires are still burning across California, including the massive Park Fire in the north.

Cooler temperatures are now helping the thousands of firefighters battling to contain the blaze, which more than doubled in size in 24 hours.

Several fires are also burning in Oregon, but worst-hit is still Jasper National Park in the Canadian Rockies.
