A study was made of the distribution of ejecta from the crater formed by exploding 20 tons of TNT at the surface of a limestone outcrop. The distributions of both in situ material and material artificially introduced into the medium before the explosion are described. Variations with distance from burst point in ejecta areal density and the size distribution of ejecta are analyzed. Relationships between ejecta distribution and site topography and geology are discussed. Suggestions are made as to further work directed toward improving methods of predicting ejecta distribution from large explosions on rock. (Author).

The purpose of the Flat Top program was to photograph the fireball, shockwave, base surge, ejecta, and early and late cloud formations on each of three separate high-explosive detonations used to simulate equivalent detonations of nuclear devices. Excellent results were obtained on 16-mm, 35-mm, and 70-mm black-and-white film and 35-mm color film. Detailed descriptions of the photographic instrumentation and representative samples of the film records from each of the three events are included in this report. Recommendations for improved coverage on future experiments of this type include the use of an additional close-in photo station, faster framing rates, the use of a timer as a backup on camera shutter closure systems, and more extensive use of color film.

"This volume atempts to explore and clarify the relationship among the geological records, the extinctions, and the causes of catastrophes for life in Earth's history. Most of the papers address the geological record and the extinctions across the Cretaceou-Teriary boundary, and the buried Chicxulub structure that is now consensually deemed to be of impact origin and to be intimately related to that boundary."
