Researchers at the University of Lausanne (UNIL) used a simulation to reconstruct the journeys of giant rocks transported across the Alps [1, 2].
This study provides a visual explanation for the presence of massive boulders located far from their original geological formations. By modeling the movement of these rocks, scientists can better understand how the landscapes of modern Switzerland were shaped during the last Ice Age [1, 3].
Thousands of giant rocks scattered across Switzerland have puzzled people for centuries, a researcher at Knowridge said [3]. Many of these huge boulders are sitting far from the mountains where they were originally formed [3]. The new simulation allows the team to trace the paths of millions of rocks that influenced the region's topography [1, 3].
According to the findings, these movements occurred approximately 24,000 years ago [1, 3]. The research team utilized ice flow modeling and geological analyses to determine the trajectory of the stones [4]. Scientists said it is possible that glaciers carried the stone part of the way during the last Ice Age [4].
"For the first time, researchers at the University of Lausanne (UNIL) have reconstructed the journeys of these giant rocks across the entire Alpine region using a simulation," a researcher at UNIL said [1].
The simulation serves as a tool to bridge the gap between the current location of these boulders and their points of origin. By recreating the glacial flow of the prehistoric era, the UNIL team can now visualize the specific routes these massive objects took as they were pushed across the Swiss landscape [1, 3].
“Thousands of giant rocks scattered across Switzerland have puzzled people for centuries.”
This simulation transforms static geological observations into a dynamic map of prehistoric environmental change. By proving that glaciers acted as conveyor belts for massive boulders 24,000 years ago, the research helps geologists refine their understanding of glacial erosion and deposition patterns, which are critical for mapping how ice sheets have historically altered the Earth's crust.
