The government had put in large 

 areas of grass on the dunes near the 

 mouth of the Siuslaw River about 1917 

 in an effort to keep the sand from blow- 

 ing into the river. Some of this grass 

 still flourishes, but much of it has been 

 blown out and the sand still blows into 

 the river. The Forest Service has 

 stopped the grazing and the sand move- 

 ment has been slowed up.

*Crater Lake National Park (A3). 

 This area of about 249 sq. mi. lies on the 

 summit of the Cascade Range, about the 

 wonderful lake of that name. It is 

 surrounded by National Forest lands. 

 It is covered chiefly with the type of 

 forest characteristic of the upper slopes 

 in the Cascades. A few exposed peaks 

 have alpine conditions. Much of the 

 Park is in its absolutely virgin condition 

 and is likely to remain so. Trapping, 

 timber cutting, hunting and grazing of 

 stock are forbidden. 



It may be reached during the summer 

 months by stage from Medford or 

 Klamath Falls, Ore. T 7 . T. M.
