The Mapleton Meteorite 101 v. 77 steep hill (fig. 35) in the northwest quarter of Section 15, Township 85 N., Range 42 W., about three miles east and one mile north of Mapleton, Monona County, Iowa (42° 10' 47" N.

About X Vs. crop up with divergent reports, and attempts are made to connect the find with one of these reports. The finding of the Mapleton was no exception. Stories of a "fire-ball" streaking across the sky at such and such an hour, day, and year, poured forth in rapid succes- sion, but none of these stories could be verified, much less associated with the Mapleton. However, it is well to point out here that only the surface of the meteorite had suffered oxidation, as evidenced by the partial alteration and decay of the fusion crust. The iron is otherwise remarkably well preserved, and, because of this excellent state of preservation, it may be assumed that the fall took place in recent decades. Apparently, the meteorite is only a portion of the original mass, as it appears to have been broken. The disruption must have taken place at a considerable altitude while the meteorite still had high velocity. This can be surmised by the presence on the broken side of elongated furrow-like depressions or pittings that could hardly have been formed under reduced velocity. >• v^.
