So anyway, the deep hydrosphere would be around 6 kilometers below the surface, kept liquid by geothermal heat. However, it's easier for water to stay liquid if it's already melted than it is for it to melt in the first place. If the water metls first, then according to a couple of studies, it stays liquid indefinitely below only 100 meters of gravel in Martian conditions from the internal heat of Mars. Ice is less insulating than gravel, but it can stay liquid indefinitely below 600 meters of ice. Without any geothermal hot spots, just the internal heat of the planet itself. |

With that background that new discovery of a lake at a depth of 1.5 km wasn't that surprising, if it somehow got melted at some point in the past even if it was just ordinary water, it should remain liquid. They'd been looking for them for some time because of that calculation. |

Seems it is probably laced with salts and very cold because the radar imaging of the ice showed ice that seemed to be much colder than 0 C as otherwise it wouold be more optically opaque to the radar. |
