 EXPLORING THE COAST IN 



Geographic Harbor, which was discovered by the expeditions, affords ready means of 

 access to the whole region. Only 50 or 60 miles of automobile road is needed to open up all 

 the wonders of the area to the public. When that is constructed, the traveler may tour the 

 Katmai National Monument as easilv as he now visits the Yellowstone.

 MOUNTAIN WAI/E OP GEOGRAPHIC HARBOR 



On entering this haven, one has an unusual opportunity to study volcanic action ; for, 

 contrasting with the ash of the recent eruption, there is an enormous lava flow that poured 

 down the bay in Tertiary times, forming beautiful columnar joints, as seen in the nearer cliff.
