GEOLOGY AND PALEONTOLOGY 
INTRODUCTION 
BY GROVE KARL GILBERT 
The papers in this volume represent the results in geol¬ 
ogy and paleontology of the Harriman Alaska Expedition. 
The narrative of the Expedition and an account of its organ¬ 
ization are given in the first volume of the series, but as 
not all readers may have access to the entire series, a cer¬ 
tain amount of repetition may be permitted in this place. 
The Expedition occupied the months of June and 
July, 1899. Organized by Mr. E. H. Harriman, of 
New York City, and conducted at his expense, it was 
originally planned as a holiday excursion for his family 
and a few friends interested chiefly in hunting. The 
plan was afterward enlarged so as to include scien¬ 
tific work, and was further modified by giving the re¬ 
search corps practical control of the route and other 
details affecting their work. There were twenty-five 
scientific workers, representing a wide range of subjects 
— ethnology, zoology, botany, geology and geography. 
Five were accounted members of the geologic division, 
of whom three gave exclusive attention to geology and 
physical geography, while the others were partly occu¬ 
pied also with studies in ethnology and botany. The 
geologists were Dr. Wm. H. Dali, of the Smithsonian 
Institution and the United States Geological Survey, Mr.
