在火星盖尔陨坑夏普山山脚的宽阔斜坡上，被风吹得锋利的岩石覆盖着。被称为鳄鱼背岩石的崎岖不平、鳞片状的外观被“好奇号”火星车在执行第3415号任务（2022年3月15日）时通过数字拼接的桅杆摄像头拍摄到。之前在鳄鱼背岩石上行驶导致了火星车车轮的损坏，所以好奇号团队成员决定掉头，走另一条路继续火星车的攀登。自2014年以来，好奇号一直在盖尔陨石坑中心5.5公里高的山峰上爬升。在爬升的过程中，这个经久耐用的探测器已经能够探索数十亿年前火星上由水形成的地层。

Wind-sharpened rocks known as ventifacts cover this broad sloping plain in the foot hills of Mount Sharp, Gale crater, Mars. Dubbed gator-back rocks their rugged, scaly appearance is captured in these digitally stitched Mastcam frames from the Curiosity rover on mission sol 3,415 (March 15, 2022). Driving over gator-back rocks before has resulted in damage to the rover's wheels, so Curiosity team members decided to turn around and take another path to continue the rover's climb. Curiosity has been on an ascent of Gale crater's central 5.5 kilometer high mountain since 2014. As it climbs, the durable rover has been able to explore layers shaped by water on Mars billions of years ago.
