Mysterious Moving Forest Scene

the prompt

Dense redwood forest during heavy fog. A wildlife photographer spends the night inside a fire watch tower. Everything seems normal. Until dawn. Entire sections of the forest have moved. Mountains are unchanged. The roads are unchanged. But the trees are somewhere else. Then he sees it. Far away. An entire forest walking. Thousands of trees moving together. Roots lifting from the ground. Branches swaying. The visible danger grows: highways disappear beneath advancing trees radio towers vanish inside the moving forest rivers change direction abandoned houses become engulfed The photographer drives desperately through foggy roads. Behind him: The living forest slowly advances. At sunset giant trunks tower above the highway. Then the movement stops. The forest stands silent. As if it had never moved.
