Striking similarities between Martian and Alaskan Landscapes

From the report: Little did Bucknell University geology professors Craig Kochel and Jeffrey Trop know, as they were working in Alaska, that they would soon predict one of the most important planetary observations ever made.

Although geologists can usually tell what shapes the landscape around us, it was a mystery what formed the Mars-like features found in Alaska.

The conditions on Mars are quite different than anything experienced on Earth. For example, Mars is much colder than even the Arctic — the average martian temperature is -81 degrees F (-63 degrees C) — and the planet's atmospheric pressure is lower than Earth's. Still, for the same features to be present on Earth and Mars, the two professors suspected similar processes would have made them.
