In the February edition of METEORITE, Geoff wrote:

NOTKIN G. (2001) Legend of Glorieta Mountain
(METEORITE, Feb. 2001, Vol. 7, No.1, pp. 24-27):

V.F. Buchwald supported an aerial breakup theory, and in his
Handbook of Iron Meteorites stated that the " t h r e e largest
blocks are oriented individuals with fusion crust and regmaglypts,"
and that their surface features were "in harmony with a late breakup
in the atmosphere, so that these masses fell close together."

Cohen even mentions 13 highly oriented pieces in:

COHEN E. (1903) Meteoritenkunde, Vol. 2, pp. 162-163:

"According to Brezina, Glorieta [Mountain] is a good example of
noticeable orientation, although disruption took place [high] in the
atmosphere; all the 13 pieces found so far and ranging between 67.5 kg
and 300 gr, are highly oriented. The disruption must have occurred at
quite a considerable height, as the exposed surfaces have been partially
covered by a secondary melting layer; its cosmic velocity, however, had
already been retarded so thoroughly that the oriented surface features
could not be wiped out anymore."

Best wishes,

Bernd
