The spiral pattern is due to the Coriolis effect, which is when a planet\u2019s rotation bends the course of winds.<\/p>\n<p class=\"paywall\">The darker parts of the spiral are actually deep canyons, which have been cut over a long period by the springtime winds. The Chasma Boreale, which is visible to the right of the center of the polar cap in the image, is particularly spectacular. It is as long as the Grand Canyon (about 450 kilometers) and up to 2 kilometers deep.<\/p>\n<figure class=\"AssetEmbedWrapper-eVDQiB byBkf asset-embed\">\n<div class=\"AssetEmbedAssetContainer-eJxoAx dBHGoQ asset-embed__asset-container\"><span class=\"SpanWrapper-umhxW kGxnNB responsive-asset AssetEmbedResponsiveAsset-cXBNxi eCxVQK asset-embed__responsive-asset\"><picture class=\"ResponsiveImagePicture-cWuUZO dUOtEa AssetEmbedResponsiveAsset-cXBNxi eCxVQK asset-embed__responsive-asset responsive-image\"><noscript><img decoding=\"async\" alt=\"Image may contain Person and Outdoors\" class=\"ResponsiveImageContainer-eybHBd fptoWY responsive-image__image lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" data-src=\"https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_1600%2Cc_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg\" data-sizes=\"auto\" data-srcset=\"https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_120,c_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg 120w, https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_240,c_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg 240w, https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_320,c_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg 320w, https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_640,c_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg 640w, https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_960,c_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg 960w, https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_1280,c_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg 1280w, https:\/\/media.wired.com\/photos\/67a0d5b68bcda918ed4657fb\/master\/w_1600,c_limit\/7_e5-pia26517-hirise-views-frosty-martian-dunes.jpg 1600w\" data-sizes=\"100vw\"\/><\/noscript><\/picture><\/span><\/div>\n<\/figure>\n<p class=\"paywall\">The strong spring winds also move sand dunes on the Martian surface, just like winds do in deserts on Earth.<\/p>\n<p class=\"paywall\">The white stuff you see in the image is frost surrounding the elevated dunes, which remain static while frozen.
