adjacent; many fine waterfalls. Ford's 

 Terror, a branch of Endicott Arm, five 

 miles long, a quarter-mile wide, with 

 entrance 300 ft. wide; at its head a 

 glacier, recently tidal, now ending on 

 land, also several fine cataracts. Shores 

 of lower bay densely clothed with 

 spruce-hemlock forest; upper portions, 

 especially Ford's Terror, show all 

 successional stages. See John Muir: 

 Travels 171 Alaska, chapter on "Sum Dum 

 Bay."

Knyg Lake. Lake, U mi. long, § mi. 

 wide, draining into Stikine River by 

 outlet stream 3 mi. long; surrounded by 

 cliffs 3000 ft. high, with several water- 

 falls; a glacier enters upper end and dis- 

 charges very large icebergs. All stages 

 in plant succession following glacial 

 retreat; fine display of wild flowers 

 around lower end in early summer. 

 Along outlet stream may be seen all 

 stages of flood-plain succession, from 

 willow-cottonwood, through alder 

 thicket to spruce-hemlock forest.
