    Are these black hollow spots craters?

    Hi There. I see overlapping fans on the left of the image, with blotches below. There are some 'spider channels' between them. In the top right corner is a large blotch. The small round features in this blotch are lumps (or bumps) in the surface.

    Sunlight comes in from the lower right of these images so the lumps are lit up on the lower side, with the top side of the lumps being in shadow. Does that help? 😃

    Yes that helps! Thank you for clarifying with me. I will classify them appropriately in the future 😃

    My pleasure. 😉 If you'd like to see more examples of lumps and bumps on Mars, have a look at Angi's project here: http://talk.planetfour.org/#/boards/BPF0000008/discussions/DPF0000g25 Feel free to offer up a link to your image here.
