Fires tend to go through a daily ebb and flow of activity. You can hear examples of that in these recordings made at the "heel" of the Maple Fire, a lightning-caused fire that started in Yellowstone on August 8. Earlier in the morning, after the previous night's cooler temperatures and buildup of relative humidity, the fire was less active. As the day heated up and the relative humidity dropped, the winds kicked up and the fire grew significantly.
