In a study recently published in the Journal of Geophysical Research: Planets, researchers from the University of Arizona used drones equipped with ground-penetrating radar to learn more about two debris-covered glaciers in the US. These so-called ‘buried glaciers’ bear striking resemblance to buried ice deposits observed on Mars and could therefore guide the search for water on the Red Planet. … These kinds of glaciers only make up 5% of glaciers globally, but they’re found in mountainous regions across the world, including in warmer areas such as Colorado and California, where debris insulates the ice underneath and stops it from melting. On Mars, similar-looking, debris-covered glaciers are found in mid-latitude regions.
