Parts II and III. Sandia Laboratory group and Sandstone report no. 41 34. CLASSIF. LEVEL TEXT unclassified 950. ABSTRACT The facts and events presented here will serve as a brief summary of various activities in chronological order which are presented for the purpose of acquainting those who are interested with the necessary preparations on the part of Sandia Base personnel who were involved in Operation Sandstone. This report is not meant to be a complete historical document and will, therefore, include only those phases in which Sandia Base (Z-Division) participated. However, in order to prepare this work intelligently, it is felt that a brief outline and overlap of the entire organization is essential material and worthy of review for background. The Los Alamos Scientific Laboratory had realized since late in 1946 that only through field tests and actual detonation with proper instrumentation could the experimental designs of atomic weapons be proven and thereby obtain verification of theoretical calculations. To this extent then, on April 3, 1947, the General Advisory Committee recommended that serious consideration be given a proposed test program.
