 Stains in the crater M1400134: in this image what's most interesting is that it's setting within 1 degree north of the Equator, and, less than 6 degrees east of the Prime Meridian:
Longitude of image center: 324.43°W
Latitude of image center: 0.84°N

Meanwhile, NASA is still rattleing on about "Water Streaks only appear at high Latitudes on Polar Facing Slopes," and, "only on slopes facing away from the Sun." Take a little tour of that image, and, see how many Streaks you can find that fit this description. I'm sure there are some facing the Poles, and, there are some on slopes down-Sun, but, there are as many facing in every other direction as there are which fit the description.

Also notice the difference in shades (light to dark), which indicates repeating and successive flows. The large Crater near the bottom of the Not-mapped GIF has fresh streaks, compasswise, covering around 340 degrees, and the center of that Crater is approximately 1 degree North of the Equator.

pond.jpg (241784 byte) Pond or lake; m1202473 shows a dark area inside the depression: the possible source of the liquid that modeled the landscape is the impact crater visible right above the portraited area (green). The region is dominated from a great bassin of a flat volcano (or an ancient huge impact crater that damaged the crust causing vulcanism) containing both the impact crater and the area of the image
