Interesting crusty-rusty specimen of Native Iron with strange botryoidal coatings of secondary iron oxides and hydroxides.
The old University of Copenhagen label that comes with the specimen only mentions that it's from Greenland, however it's probably from the Type Locality of Disco Island in the Kitaa Province.
