INTRODUCTION. 

 THE SOUTHERN COAST OF ALASKA. 



The southern coast of Alaska is remarkable for the regularity 

 of its general outline. If a circle a thousand miles in diameter 

 be inscribed on a map of the northern Pacific with a point in 

 about latitude 54° and longitude 145° as a center, a large part of 

 its northern periphery will be found to coincide with the south- 

 ern shore of Alaska between Dixon entrance oil the east and the 

 Alaska peninsula on the west. On the northern part of this 

 great coast-circle lies the region explored in the summer of 1890 

 and described in the following pages. 



From Cross sound, at the northern end of the great system of 

 islands forming southeastern Alaska, westward along the base of 

 the Fairweather range, the mountains are exceedingly rugged, 

 and present some of the finest coast scenery in the world. There 

 are but two inlets east of Yakutat bay on this shore which afford 

 shelter even for small boats. These are Lituya bay and Dry 

 bay. Ships may enter Lituya bay, at certain stages of the tide, 

 and find a safe harbor within ; but the approaches to Dry bay 

 are not navigable. West of Yakutat bay the coast is equally 

 inhospitable all the way to Prince William sound.
