Fork of the San Joaquin River and within a few miles of its 

 source. An appHcation for a reservoir site for power purposes is 

 now pending before the local officials having jurisdiction, and we 

 are informed will be acted on in a few days. The use of such a 

 reservoir site will result in the flooding and obliteration of the 

 Devil's Post Pile and the possible use of the Rainbow Falls. 

 These features were originally included within the boundaries 

 of the Yosemite National Park, but were unfortunately excluded 

 when the area of the park was diminished in 1905. 



We feel that before any such permit be granted, the situation 

 should be carefully examined to ascertain just how serious this 

 damage will be, and we urge the protection of these wonderful 

 features by the establishment of a national monument so that 

 they may remain objects of scientific and scenic interest. 

 Photographs of these features are enclosed herewith. 



Very respectfully,

The Mazama Club Outing to the Three Sisters, in Southern 

 Oregon, last August, proved to be of exceptional interest. The 

 region is comparatively Httle known, maps are hard to find and 

 not altogether to be relied upon, so to the great beauty of the 

 scenery and the interest attaching to the unusual volcanic forma- 

 tions is added the never-failing charm of exploration. The three 

 peaks composing the group lie close together, their dark, rugged 

 summits encircled by glaciers of considerable magnitude. The 

 Middle Sister, the most accessible and hospitable, boasts quite an 

 enrollment of visitors ; the South Sister, highest of the group, 

 a little over 10,000 feet, shows scattering records of ascents dur- 

 ing the last ten years, numbering perhaps not more than a score 

 until our party went to augment the roll. But the North Sister, 

 a black, wicked-looking mountain, could show only two names 

 on one of the three pinnacles comprising its summit, and it was 

 not until last summer that records were placed on all of its 

 crumbling crags. The following letter from Mr. H. H. Prouty 

 of Portland, Oregon, describes the hazardous climb that he alone
