1) ELBOW STRUCTURE:

This structure, described by G. DeMille, Journ. Alberta Soc. Petrol.
Geologists, 1960, vol. 8, p. 154, is included in a list of possible
meteorite craters due to W.H. Bucher (Monod, 1965, p. 35.).

2) HICKS DOME:

Mentioned by W.H. Bucher (Nature, 1963, vol. 197, p. 124); Further
literature, see Monod, 1965).

3) MANSON:

A large circular disturbed area concealed by glacial drift (W.H. Bucher,
Amer. Journ. Sci., 1963, vol. 261, p. 597; R.S. Dietz, ibid., p. 650).

4) VERSAILLES DISTURBANCE:

W.H.Bucher, 1963, Cryptoexplosion Structures Caused from Without or from
Within the Earth? ("Astroblemes" or "Geoblemes"?), Am.J. Sci., 261,
597-649.

5) WELLS CREEK BASIN:

Five craters, from 2 by 3 miles oval to 375 feet in diameter, occur in a
line; there is extreme brecciation and shattercones indicating explosive
force from above (C.W. Wilson, Jr., Bull. Geol. Soc. Amer., 1953, no.
64, p. 753; W.H. Bucher, Nature, 1963, vol. 197, p. 1241; and Amer.
Journ. Sci., 1963, vol. 261, p. 597

Best wishes, Bernd.
