How long does it take for the sleeping bear dunes to move?

The Sleeping Bear Dunes, located in Michigan, are dynamic and constantly changing due to natural forces like wind and water. While the dunes can shift significantly over time—sometimes moving several feet per year—the exact speed of movement varies based on environmental conditions. Factors such as wind direction, speed, and moisture levels play a crucial role in how quickly the dunes can migrate. Overall, it's a gradual process rather than a rapid one.
