Esker Riada

An esker riada is like a big long hill that was made by very hardworking ice and water a long time ago. The ice and water moved through an area and left a bunch of rocks and dirt in a long line. Then over time, the rocks and dirt got stuck together and formed a tall hill. Esker riadas are special because they can be really long, sometimes stretching for many miles! People often think they are important because they can help us understand what the environment was like in the past and how the world has changed over time.
