Yellowstone September 2024
As Yellowstone slowly drifts towards autumn, the last days of summer are just beginning to show signs of transformation. Young aspens hint at fiery yellow. Willows blend red, orange and gold. The cottonwoods along Lamar River still hold their green leaves as the grass in the valley fades to brown. Each day more changes appear. By the end of the week snow will dust the mountain tops, and hillsides will become a collage of color.
