BOULDER COUNTY. 



(Area, 768 square miles; estimated forest area, 275 square miles.) 



This county is situated in the north-central part of the State. It is 

 bordered on the west by the main Eocky Mountain range, and is well 

 watered by streams tributary to the South Platte River. The western 

 half is mountainous and timbered j about one-third of the timber is 

 good, and one-fourth burned over, with a young growth following. The 

 IDrincipal arborescent species are. Yellow and White Pine, Spruce, and 

 Fir. The timber is scattered over nearly all of the mountainous por- 

 tions of the county, while along the foot of the range it is quite dense. 

 After forest fires, the second growth usually consists of wild Maple, 

 Alder, and shrubs. 



The eastern third of the county is rolling and valley-land^ most of 

 which is suitable for fjirming purposes. 



CHAFFEE COUNTY. 

 (Area, 900 square miles ; estimated forest area, 500 square miles.) 



This county, which occupies a central position in the State, is almost 

 surrounded by mountain ranges. It contains a large proportion of farm- 

 ing and grazing land, and is abundantly watered by the Arkansas River 

 and its tributaries. 



About two-thirds of the county is timbered. Near the summits of the 

 mountains is Spruce^ below them Yellow Pine, and in the foot-hills and 

 mesas Piiion and Scrub Pine j along the streams are Willow — (Black or 

 Narrow-leafed), Cotton- wood, and Aspen. The timber land is mainly sit- 

 uated along the eastern slope of the Continental Divide, which forms 

 the western boundary of the county, and in the range of hills between 

 the South Park and the Arkansas River. The timber in the more open 

 valleys of the river is largely Pinon, great quantities of which have been 

 cut and converted into charcoal for the use of the smelters of Leadville. 

 Pueblo, and Denver. There are a number of saw-mills, and a great 

 many railway cross-ties are being cut. This consumes the best part of 

 the timber. 



CLEAR CREEK COUNTY. 



(Area, 450 square miles; estimated forest area, 200 square miles.) 



This is pre-eminently a mountainous county. The main snowy range, 

 with an altitude of 14,000 feet and more, extends along the entire western 

 boundary. It sends off lofty spurs, many of the peaks rising far above 

 the timber line, and these, in parallel ranges, traverse the county from
