This image is taken by Mastcam 100, which is the same 2MP CCD, but with a 100mm (telescopic) lens in front. It’s pointing in the same direction as Mastcam 34 — it’s just more zoomed in. NASA has provided the raw (non-color-corrected) version, if you want to see what Curiosity actually sees; and there’s an annotated version, too. In brief, the gravel in the foreground is 125 meters away from Curiosity, the impact crater (about a third of the way up the image) is about 3.5km (2mi) away, and the farthest point is around 16km (10mi) away.
