Can you explain a little further what you mean by a 'topographical' marker?
I think you may have a few members out there scratching their heads over the term 'cadastral' but it's just a fancy way of saying land parcel or lot boundaries. Most cadastal and even control survey monuments are steel with brass or bronze identification caps. I've never seen aluminum and wonder how well they would stand up being pounded into the ground. That, plus the ablilty to locate them with a typical survey 'bar finder' (or in the old days a 'dip meter') which operates on an iron/magnetic principle.
