Abstract
II.
SINCE Gilbert (in 1887) published his classical monograph on the geology of the Henry Mountains, in which he gave to the world for the first time a clear and connected account of the nature and occurrence of Laccolites, we have waited many years for further original work on this type of physical structure in America. A study of the writings of Peale, and of the exquisite panoramic drawings of Holmes, made it abundantly clear that laccolitic masses must be frequent in the United States. Mr. Whitman Cross has now collected a number of instances from Colorado, Arizona, and Utah.2 He has remarked on their structure so far as it has been made out by these observers, by Emmons, and by himself, given a description of the characters of the rock of which the laccolites consist, and offered some remarks on the general theory of laccolitic structure.
