Impact melt tongue
Another beautiful impact melt feature found in Jackson crater! This thin flow of impact melt spreads across the surface of a terrace. The boulders around the edges of the flow may have eroded out of the flow, or were carried there by the impact melt. In the upper right hand corner of the image, there are many large boulders, as well as smooth areas which are impact melt. The impact melt flow seems to originate from that area. Since the large boulders are on top of the impact melt, the impact melt probably landed in the spot first, and the large boulders are a later addition, falling down from a point higher up on Jackson's wall.
