A field test held in the Hopi Buttes, Arizona, was planned to test geological, geophysical, and analytical operations and instruments that are of potential use in Apollo Extension Systems lunar surface missions. The test was conducted under "shirt-sleeve" conditions, but potentially useful methods of recording and compiling information during lunar exploration were employed. The test showed that by using specially planned procedures, field and analytical information can be evaluated during field operations and compiled at a location that is remote from the field. It also showed that the more information that is analyzed as operations progress, the more effectively can succeeding operations be conducted. Experience in field operations under these conditions appears to be a major factor in collecting and analyzing critical scientific information.
