There are many locations in the mid-latitudes of Mars that look like material has flowed. This image shows an example flowing downhill between two ridges.

Mars Glaciers Are Purer And More Uniform Than Previously Thought
On the slopes of Martian mountains and craters clings what appears to be flowing honey, coated in dust and frozen in time. In reality, these features are incredibly slow-moving glaciers, […]
![Site locations and hypothesized pan-Arctic glaciation. ODP Site 910 and MD99-2277 (red dots) are located in the Eurasian sector of the Arctic Ocean and central Nordic Seas, respectively. Site 910 lies just beyond the margins of the maximum MIS 2 Eurasian ice sheets [gray dashed line; based on (51)], while MD99-2277 was simultaneously covered by sea ice. However, both sites are hypothesized to have been fully glaciated under the maximum pan-Arctic ice sheet extent (white shaded extent with blue flow lines) proposed by Hughes et al. (75) [modified from Jakobsson et al. (7) and Geibert et al. (3)]. - Science Advances](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/07/Ice-World-Oceanography-The-Arctic.png?resize=1200%2C718&ssl=1)

Ice World Oceanography: The Arctic Ocean Remained Open To Life During Ice Ages
For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages.

During Snowball Earth Early Life May Have Sheltered In Meltwater Ponds
When the Earth froze over, where did life shelter? MIT scientists say one refuge may have been pools of melted ice that dotted the planet’s icy surface.

Four-million-year Marinoan Snowball Shows Multiple Routes To Deglaciation
Twice during the Neoproterozoic Era, Earth experienced runaway ice-albedo catastrophes that resulted in multimillion year, low-latitude glaciations: the Sturtian and Marinoan snowball Earths.
