Caption by Space Station Academy student: This image shows the junction of the Madre de Dios and Beni rivers near Riberalta, Bolivia in South America. The Madre de Dios River joins with the Beni River in northern Bolivia and continues through Brazil as a tributary of the Amazon River. Rich greens along the river show the rainforests with one city (Riberalta) where the rivers meet. The curving river supports lush rainforests and diverse wildlife. The sharp contrast of the river's brown, whimsical trail through the land's rich green makes this image strikingly beautiful.
