Active Gullies in Kaiser Crater
HiRISE PICTURE OF THE DAY: 30 JUNE 2025
Active Gullies in Kaiser Crater

This megadune in Kaiser Crater is very interisting because it may have some active gullies formation on its surface. Other dune with gullies are also located here beside the megadune. Regular monitoring is important to understand the formation mechanism of the gullies and their seasonality.

Since July 23, 2023, HiRISE observations have lacked data from the RED4 CCD due to a hardware issue, creating a gap in the middle of image products and reducing the color swath to 1 CCD width. We are investigating the hardware issue and may be able to acquire some RED4 data in the future.

Glacial (Ice) or Lava Flow?
Glacial (Ice) or Lava Flow?
The geologic setting and latitude here suggest this is a glacial (ice-rich) flow, but the surface is broken into plates like many lava flows on Mars.
