Eberswalde Crater is an approximately 65-kilometer diameter, closed basin crater. It contains a delta, which indicates that flowing water was present for an extended period of time in the past.
Parts of the crater have inverted channels that have higher relief because a more resistant material was deposited in the channel and therefore it was less susceptible to erosion than the surrounding area. The image also shows resistant knobs and mounds as well as a scoured surface.
It’s always helpful to put something in the photo for scale. A pen or pencil, rock hammer, human or human limb, and hat are the geologist’s favorite articles to define scale.
It would also be helpful if you mentioned what planet (assuming it is a planet) this photo is from. Then we can talk about putting a rock hammer in the photo for scale.
And I don’t see no steeenkin crater in that photo.

From the “toolbox”: how is “Local Mars time” calculated?
Sorry. You are supposed to be able to click on it and go to the NASA site with the hammer. The link fell off. I’ll look for it and put it back when I find it. This is obviously Mars.
It certainly didn’t look like the Knobs around me (central KY), not enough trees. rb
@ kevin
You’re looking at the floor of the “steeenkin” crater!
