down the valley. Lodgepole pine forest is the general covering of the 

 surrounding hills, while the level portion of the park is a grassland area. 

 Streams and ponds are generally fringed with a willow-birch-honey- 

 suckle scrub, while alder-willow thickets and aspen groves occupy 

 seepage areas. Moor, meadow and dry grassland cover the more level 

 parts of the park proper. Many different formations and associations 

 can be recognized. Edaphic conditions, seasonal aspects, zonation, 

 principal and secondary species, the effects of glaciation — these have all 

 been touched upon briefly. Attention is called only to more obvious 

 ecological facts. Various problems are suggested for study. 



It may be well to note that the present paper is intended primarily 

 for use of students at the University of Colorado Mountain Laboratory.
