A search at the site of the Goose Lake meteorite impact point revealed large numbers of nickel‐iron and laminar oxide fragments. Evidence that the Neumann lines in the nickel‐iron fragments are quite dissimilar to those in the main mass of the meteorite suggests that their origin is independent, that they were swept up by the meteoroid during its long life in orbit around the sun. Only those fragments which found their way into the cavities of the main mass were recovered, all others being swept away by the air stream during its fall. Cavity transportation explains their abundance locally at the impact site, as well as protection against aerodynamic heating. The laminar oxide fragments, similar to those found at Canyon Diablo, appear to have come from another fall.
