Operation Sun Beam, Shots Little Feller I and II. Project Officer's report - Project 1. 9. Crater size and shape
Objectives of Project 1.9 were to obtain the dimensions of the apparent and true craters formed in desert alluvium by the Little Feller II event, a low airburst, and to measure the permanent earth deformation occurring within the plastic response zone. A later requirement was the measurement of the apparent crater formed by Little Feller I, fired ten days after Little Feller II. The Little Feller II experiment used colored sand columns, vertically embedded in the vicinity of ground zero, to enable postshot measurement of permanent earth deformation below the apparent crater. In this report, postshot excavation and mapping of these columns is discussed, the results are evaluated, and correlation is made with previous cratering data.
