Craters and Crater Springs of the Rio Salado
The Journal of Geology, 1948The craters and the crater springs are located approximately 8 miles, air line, northwest of the Jemez Indian Pueblo, which is some 45 miles northwest of Albuquerque, New Mexico. They lie on the eastern slope of the valley of the Rio Salado, a tributary of the Rio Jemez, which, in turn, flows into the Rio Grande.

Crater Studies: Crater Measurements
1967Abstract : Project Pre-Gondola I, a series of four 20-ton high explosive cratering detonations, was conducted by the U. S. Army Engineer Nuclear Cratering Group during October and November 1966 in order to determine the cratering characteristics of the Pre-Gondola project site located about 18 miles south of the town of Glasgow, Valley County, Montana.

Abstract Impacts of small celestial bodies, in terms of energy density, occupy the range between ordinary chemical high explosives and nuclear explosions. The high initial energy density of impact gives them some features of an explosion (shock waves, melting and vaporization, mechanical disruption of target rocks).

Lonar Crater, India, a Meteorite Crater?
Meteoritics, 1964AbstractA recent field reconnaissance by one of us (ECL) has tended to support the view that the Lonar Crater, India, is probably a Quaternary meteorite crater. This origin is suggested by the high degree of circularity, the depth to diameter ratio, the breccia of crushed rock revealed by drilling, the quaquaversal dip of the surrounding country rock ...

Comet craters versus asteroid craters
Advances in Space Research, 1991Abstract The assumptions used to determine whether active comets or earth-crossing asteroids currently dominate the terrestrial cratering rate are reviewed and intercompared. The principal sources of uncertainty are the number and mass distributions of earth-crossing bodies, the adopted crater-diameter scaling law, and the question whether the ...

Palaeomagnetism of the Vredefort meteorite crater and implications for craters on Mars
Nature, 2005Magnetic surveys of the martian surface have revealed significantly lower magnetic field intensities over the gigantic impact craters Hellas and Argyre than over surrounding regions. The reduced fields are commonly attributed to pressure demagnetization caused by shock waves generated during meteorite impact, in the absence of a significant ambient ...

To break the stalemate at Petersburg, a coal-mining engineer in a Pennsylvania regiment conceives a plan to tunnel under the Confederate works and plant a powerful mine that can blow a hole in the line for U.S. troops to exploit. The chosen assault troops are the Fourth Division of U.S. Colored Troops-trained to attack around the resulting bomb crater.

Meteoritics, 1966
Abstract Recent observational evidence emphasizes the importance of craters as a prominent surface characteristic of the smaller planetary bodies in the solar system. Craters of similar appearance may have very diverse origins. An initial assumption as to the type of origin should not influence an impartial and detailed physical study of any given ...
