It's now thought that these could occur almost anywhere on Mars if the right mixtures of salts exist on the surface, even possibly in the hyper-arid equatorial regions-as it does not require the presence of ice on or near the surface.
It's now thought that these could occur almost anywhere on Mars if the right mixtures of salts exist on the surface, even possibly in the hyper-arid equatorial regions-as during deliquescence, the humidity is taken directly from the atmosphere. It does not require the presence of ice on or near the surface.
