Bill Cassidy and the Campo del Cielo Strewn Field (1960′s)

Bill Cassidy shares some of his pictures from the Campo del Cielo strewn field taken in the 1960’s.

During a trip to Pittsburgh, Pennsylvania last week, I stopped-in at University of Pitt to pay a visit to Professor Emeritus Bill Cassidy. It was a treat to talk to him about his work in the early days with the Japanese in Antarctica. But it was an added treat when Bill started to discuss his even earlier work in the Southern Hemisphere – his collaboration with the Argentine researchers at the Campo del Cielo strewn field in the 1960s. The results of all of this field work are well-published. I’ve listed them below at the end of this article under “Academic References”. You can find these on-line and published in the “Supplement” issue (Vol. 45, 2010 July) of the Meteoritical Society journal, Meteoritics & Planetary Sciences (M&PS).

Here are some images of pictures taken “from the field” which Bill Cassidy shared with me:

This was supposed to be a "posed picture" of the recovered meteorite with the mayor of the local village in the Campo del Cielo strewn field, but several families with their children arrived at the same time.

I wish I could have spent more time talking with Bill Cassidy, but I had pressing family matters to attend, and Bill had to return to his current project, which is no surprise that the topic is “impact-stressed” iron meteorites from the craters in the Campo del Cielo strewn field in Argentina.
