"METEOR CRATER: THE FIRST HUNDRED YEARS OF
EXPLORATIONS"
By: Jim Tobin - Mr. Tobin, the author of the book by the same name, has now made his
extensive studies of Meteor Crater available in CD-ROM format. The following
information is condensed from a book review written by Martin Horejsi, which appeared in
"Meteorite!" magazine, May 1999, P. 41-42. The CD is laid out in six
sections. Navigation is easy, using obvious buttons and colored frames around graphics to
indicate active links. The material on the CD is coded so it can be read using any html
viewing program.
The first section begins with an introduction to the Solar System and the small bodies
that cause impacts on Earth. The importance of this section is to provide background
information, in which to place the resulting impact site here on Earth. The second
section, entitled History of Explorations, provides an excellent, in-depth story full of
pictures beginning in 1891. The early mining operations at Meteor Crater are a main focus,
but this section also chronicles the interesting journey of scientific thought as it
evolved through time.....it is hard to believe both how little, and how much, scientists
knew about meteorites at the turn of the century compared to our current knowledge. The
third section, Canyon Diablo Irons, describes the actual meteorite material found at the
crater site. Explanations for impact material are provided, along with several pictures.
Part four, Moment of Impact, contains more meteorite images as well as text explaining the
scientific information gleaned from the artifacts remaining after the impact. The
Conclusion contains a wrap-up of the craters history, along with its place in the
surrounding geology. The section entitled Other Craters offers a glimpse into eight other
cratering events. The final section covering Meteor Craters history is the Timeline.
From 1886 to 1975, all major events at the crater are listed in chronological order. The
user is then treated to a Walking Tour of the crater, featuring information about specific
locations around the rim, as well as down to the crater floor. Meteor Crater is closed to
public exploration, making this CD the only way most of us will ever explore the crater.
Tobin has also included a reprint of Barringers 1909 paper about Meteor Crater, as
well as some additional information about other craters and impact structures. In addition
to all of the above, there is a very informative section covering tektites. In summary,
this CD-ROM is a wealth of information for anyone interested in meteorites and craters
accompanied by nice, easy to listen to electronic music.
