the location of Empire City, the mountains surrounding it, the 
deserted beaver dams and the view obtained of Bald mountain, 
Mount Flora and Parry’s peak, of the Middle Park country, 
Grand River and its tributaries. He mentions “mazes of Beaver 
Dams” where you “flounder among the matted roots of willow 
thickets.” Then he discusses the places then and now known as 
Sulphur Hot Springs and the main valley of Grand river, “which 
forces its way through transverse ridges.” Another region visited 
by him in northern Colorado was Long’s peak. 
The exploring party of Hayden’s Survey visited the region 
and made a study of it. Whether J. M. Coulter who was the 
botanist for some of Hayden’s Surveys, visited the region, we do 
not know.^ Marvine, who was the geologist of the Survey, gave 
a good description of Mount Byers and the drainage of Fraser 
river^and its tributaries, as well as of Williams creek. 
Mount Byers, where most of the collecting was done, is the 
northwest spur of the Berthoud pass. James peak and Mount 
Byers are culminating peaks of a part of the Forest river basin, 
Williams creek coming from the Clear creek loop. The west 
sides of the peaks are all easily approached, the east side has a 
precipitous approach. The region is covered with fine timber, 
and there have been fewer forest fires here than in any other
