You will find that the largest meteorites found on Earth, all iron ones, leave no craters. The only standard explanations are that they either fell when there was an ice sheet covering the area (including Africa) or that for the Hoba West meteorite that because it is flat on both sides, much like Stanly Kubriks black stone, that it skimmed and bounced its way through the atmosphere for a soft landing. Of course any other non standard suggestions about the meteorites origins or how they got there are crazy talk. So its either glacial erratic meteorites or skimming stone meteorites at over 40,000 mph...
The Hoba West meteorite also had an interesting calcium tuffa layer on it and lime or calcium layer around it. It also has a fascinating iron shale found around it, although the Hoba meteorite is known for the fact that it is bloody solid, no fractures or cracks and does not really weather or fragment! Is the iron shale and the tuffa covering (similar to precious stones) evidence of an EU creation?
Some aspects of the nature of the Hoba meteorite are truely puzzling. On the one hand, the meteorite belongs, despite its huge size, to a very rare class of meteorites and is defined as nickel - rich ataxite. Ataxites consists almost entirely out a dense packing of the meteorite mineral taenite and do not display the otherwise typical 'Widmannstaettensche Figuren' on acid edging. Another enigma is the absence of any crater like structure. The meteorite was covered by a thin crust of calcrete at the time of discovery, but upon excavation no signs of the otherwise very typical temperature & pressure induced shock phenomenae, nor any burried remains of a crater structure were reported. During excavation an odd "Iron shale" = an odd magnetic (!) and limonite rich laminated sediment was observed in close proximity to the meteorite mass, which most probably results from long time weathering. All this support the theory, that the meteorite with its unusual form hit the earth - estimated 80.000 B.C. ago - at an very low angle, junping like a stone on water from place to place until it reached its present position.

Another interesting aspect of some iron meteorites are meteorite irons, odd and twisted shaped small iron lumps found around these iron meteorites. The photograph above is of an mundrabilla meteorites iron, these are found around the area of the Nullarbor Plain in Western Australia. Another area rich in minerals, like the Hoba meteorite area.
This
article on the fact that iron meteorites leave no craters is written from an Electrical Universe point of view, although of course not official in the slightest and I am sure that most may not agree with some of the ideas.
The end point is that are the largest iron meteorites formed where they are found, like some or most large glacial erratic rocks and boulders? For example like the Merton Stone glacial erratic in Norfolk, England.
