This picture shows a shiny polished metallic tip on what looks like an eroded rock. According to NASA this can happen when wind and sand erode softer rock away from around the core of a harder rock, exposing this kind of projection.

This is a close of of the rock projection. At the tip you can see the area that has been polished and is metallic looking. Almost looks like a mini parabolic dish…hmmmmm :^). Anyone ever watch Twilight Zone…the miniature aliens….well, ok this is just an unusual formation of rock. It is very interesting and unusual.
