Sternberg's Law Statistical Study of Surficial Gravels in North Central Montana--Part II: Analysis and Conclusions.

As was shown in Part I of this paper, a simple application of Sternberg's Law of downstream fining does not accommodate all the data included in this study. The study area includes the low-relief Great Plains and the high relief of the Rocky Mountains, good overall terrain for application of Sternberg's Law, but with some complications from isolated mountain ranges. Most of the study area exhibits evidence of glaciation, but diluvial planation surfaces are also present. Channelized flow, transport by ice, and sheet flow are all candidate processes for transport of gravel. Results from statistical analysis of 5,839 sieve analysis reports indicate a complex history for the surficial gravel deposits. [ABSTRACT FROM AUTHOR]
