Photogeology: Part L: crater morphometry
Richard J. Pike
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
Morphometric analysis of lunar craters (ref. 29-75) complements the more traditional photointerpretive study of crater morphology. These two indirect approaches to the scientific investigation of lunar craters continue to be productive because the preferred alternative method, direct field examination of specific large craters, is not being undertaken in the current...

Laurence A. Soderblom, Joseph M. Boyce
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The materials of most light or terra plains predate the lunar maria and postdate the Imbrian event. In the vicinity of the Imbrium Basin, these materials have been called the Cayley Formation (ref. 29-3) but because of the subtle diversity of the terra plains over the near side, Whilhelms and...

Wilbur L. Hartman
1972, Journal of the Fisheries Research Board of Canada (29) 899-912
In no other lake as large as Lake Erie (surface area, 25,690 km2) have such extensive changes taken place in the drainage basin, the lake environment, and the fish populations over the last 100 years. Deforestation and prairie burning led to erosion and siltation of valuable spawning grounds. Marsh spawning...
