The Martian middle latitudes (about 30-50 degrees North and South) reveal many strange landforms.

This latitude is where significant ground ice has formed and may still be present, and where the temperatures were sometimes high enough in the recent past for ice to flow. This image shows roundish landforms covered by polygons and surrounded by trenches. Some combination of ice expansion and contraction, sublimation, and flow may have created this landscape.
