- •
We found 24 RSL sites within Chryse and Acidalia Planitia (CAP).
- •
CAP RSL are likely briny and recharged via a briny aquifer.
- •
CAP RSL have an annual water budget of 1.5–5.6 m3/m of headwall.
- •
CAP RSL flow for 490 ± 40 sols spanning a solar longitude of 337° ± 11°–224° ± 20°.
- •
CAP RSL are significantly different from RSL within the southern mid-latitudes.
