Martian Orbit and Obliquity

Rocks were grouped in bands across the glaciers which indicated distinct separate flows over millions of years multiple ice ages instead of just one major ice age event. Research concluded that mars has experienced somewhere between six and 20 separate ice ages during the last 300 to 800 million years um Levi said this paper is the first theological evidence of what martian orbit and obliquity might have been doing for hundreds of millions of years. These glaciers are little time capsules capturing snapshots of what was blowing around in the martian atmosphere. It's we can just take a hike along the surface without having to drill down deep inside the crust.
