Mother Nature and Yellowstone

In 1988, there was a very big fire in Yellowstone Park. One third of Yellowstone's trees were destroyed. The tree's pine cones (which have a fire resistant exterior) exploded during the intense heat thereby spreading their seeds on the ground. As the pictures show you, new growth can be found all over the park. Apparently, mother nature has a wonderful way of regenerating itself. The fires which occur in forests are actually good for the soil. While we were traveling in the car, we saw a forest fire in the distance which was caused by lightning. I guess this is Mother Nature's recycling system!!!!!
