Layers of the Earth

When I was a little kid we would often visit my grandmother in Denver, Colorado. Then we would drive up into the mountains for some fun skiing. Driving west on 70 my mother would say, "Look Joules, the layers of the earth." Inevitably my nose would be buried in a book & she wanted to make sure I took a moment to observe the natural world. All these years later I am still looking at those layers of the earth, mostly layers of the water & sky these days, but I am thankful my mom taught me to observe the natural world.
