and scattered cottonwood and Douglas 

 fir. Forest merges into grassy mountain 

 slope, typical merging of mesophytic into 

 xerophytic in short distance. General as- 

 pect characteristic of forested plain adja- 

 cent to treeless mountain side in Mon- 

 tana. Fauna includes pine squirrel, and 

 chipmunk. The lake was wide, coarsely 

 graveled beach. Water rises in May and 

 June from 9 to 17 ft., receding in summer 

 to low level in late August. Lake 50- 

 70 ft. deep, clear, little polluted. Lake 

 fauna includes a dozen species of fish, 

 entomostraca, protozoa, and other 

 plankton 2900 ft., level, rising in three 

 directions. State preserve, shooting

 line to Dayton, and two mi. by boat, or

Flathead River Islands, t (B2.) In the 

 river between Poison and Dixon. Ten 

 islands, comprising about 2000 acres, 

 mostly flood area, largely of deciduous 

 forest, mountainous vegetation, trees 

 mainly cotton wood. These islands and 

 the river adjacent are great resting 

 places for migrant water birds, are the 

 home for many native birds, and exhibit 

 flood-plain development in various 

 stages from early to mature. They 

 should be made a permanent preserve. 

 Flathead river, also called Pend d'- 

 Oreille, is the outlet of Flathead Lake, 

 has much beautiful scenery is swift, 

 little polluted, with the fish and in- 

 vertebrates of the lake. About 2600 ft.

Isolated Forest**. (B2.) In the Jef- 

 ferson National Forest, also in the Fort 

 Belknap Indian Reservation. About 

 60 sq. mi., with deciduous and conifer- 

 ous forest, mountainous vegetation, and 

 vegetation of talus slopes and gravel 

 slides, glacial topography with moun- 

 tainous formation, the Little Rocky 

 Mountains. Isolated mountains near 

 the Missouri river, but reached from 

 Malta!, Dodsonf, or Harlem|. Valu- 

 able as showing tree growth in a semi- 

 arid section, removed from other moun- 

 tain ranges or groups. Springs and 

 creeks. Headquarters may be made at 

 Zortman or Landusky.

* Pablo Reservoir Site^. On former 

 Flathead Indian Reservation near Pol- 

 son, Mont. About 3000 acres, level 

 plain, prairie, partly filled with storage 

 water several ft. deep, from clear and 

 unpolluted streams from the nearby 

 Mission Mountains. Breeding place for 

 water birds, resting place for migrants. 

 Fenced, used only for storage site. 

 About 3200 ft. Glacial formation.

 beyond a morainal hill 450 ft. above 

 Flathead lake (a) or (h). M. /. E. 



Nine-Pipe Reservoir Site. In the 

 former Flathead Indian Reservation 

 near Ronan, Montana. About 2000 

 acres of former level plain prairie, in 

 part covered with water, a permanent 

 water reservoir, a great resting place 

 for migratory birds and breeding range 

 for water fowl, with aquatic vegetation 

 and natural prairie adjacent to the 

 water. Water several feet deep, from 

 clear mountain streams, filling in spring, 

 lowering in summer. About 3000 ft.; 

 level.

Southfork Range]. (B2.) A short 

 spur from the main range of the Rocky 

 Mountains, containing large glaciers, 

 tremendous cliffs several summits 9500 

 ft. elevation across the Middlef ork river 

 from Glacier National Park. About 300 

 sq. mi. almost wholly mountains, of the 

 same general character as Glacier Park; 

 glaciers, lakes, waterfalls, cliffs, and 

 general coloring effect as beautiful, 

 striking, and interesting as that of the 

 Park; should be added to the Park. 

 Approach from the west side, from South 

 fork river is through dense forests of 

 untouched coniferous timber with pro- 

 tected stands of large and mature tama- 

 rack (western larch) up wooded slopes, 

 and up a 2000 ft. talus to narrow summit, 

 or up almost vertical cliffs of 3000 ft. 

 Approach from the east, from Great 

 Northern railway and Middlefork river, 

 is past Stanton lake, up a ridge matted 

 with yew, along exposed and arid slopes 

 to extensive snow and ice field with 

 alpine meadows and lakes. There is 

 much glaciated country; talus slopes, 

 canyons, ravines, lakes, and rushing 

 streams are common. Chapman glacier 

 faces north and is a large field. On the
