Mars: The famous 2.6 km giant Keyhole Structure (Exclamation Mark) in sharp 4K detail. Closer detail than ever. > NASA Text: Exclamation Mark on Mars Science Theme: Landscape Evolution. Turn this image sideways (so North is to the right) and the highstanding landforms look like an exclamation mark. The origin of these hills may be difficult to understand on such ancient terrain. The straight edges suggest fractures related to faults. Maybe this feature was lifted up by the faulting, maybe the surrounding terrain has been eroded down over billions of years, or both. > VIDEO https://youtu.be/grCSrg1Dkhs MARS Keyhole Structure - Spider Plants Exposed. 4K.
