"While monitoring the surface of the mixture during reduction in atmospheric pressure, we noted the formation of surface features on the scale of centimeters, notably geysers which appeared suddenly and decreased
in activity over time. The most prominent and abundant surface features were formed between the water volume percentages of 15%-25%. Less prominent
features were also formed in mixtures with a water volume percentage of 30% and 35%."
...
"We find that liquid water, or even ice, if existing in small quantities at near surface levels can be a primary agent in the formation of surface feature formations.
"The intermediate water volume percentages that produced the most numerous surface features are similar to
those suggested for shallow regolith aquifers by Odyssey."
