When I followed your link, and clicked on "larger image" it showed an object casting that shadow.
We're going to need some resident experts to tell us what the object is...it is fairly narrow, and somewhat taller (maybe) than the descent stage of the LM...but, remember....IF the terrain on the shadowed side is not level, and is a downslope, the shadow will appear exaggerated in length.
ALSO, it needn't be much taller than the LM to lcast a longer shadow. The LM is only a few feet higher than the height of a person....
