The majority of craters in this nighttime IR image appear as bright (warm) rings surrounding dark (cooler) centers. The dark "tails" of the craters are windstreaks. The crater rims are providing a wind-shadow, protecting the dust/fines on the downwind side of the crater. The wind has removed the dust cover from the surroundings, revealing the rockier/ warmer surface. These craters are located in Syrtis Major.
