fair-sized stream about 3 miles long, from 15 feet to 30 or 40 feet wide, and from 6 
inches to 4 feet deep, flowing with a moderate current in a general SE. direction to 
the sea, into which it empties about 9 miles east from Ocean Cape. The channel is 
tortuous and the bottom is of sand and gravel. Tide water extends about 2 miles 
upstream, above a point where three houses and some drying frames are located on 
the southern bank and where the natives cure fish during the season. 
About a mile above its mouth the An-kau receives a tributary, the Tha-ghe-an, 
about one-third the size of the main stream. It is said to drain a small lake 6 miles 
to the northward, which has redfish and coho spawning-grounds. 
The mouth of the An-kau expands into a tide-water basin fully one-half mile in 
length at high water and formed by the action of the sea. At high water a canoe can 
be pulled from the mouth to a point near the third lake, and at anjr stage of the tide 
above the houses, beyond which point poling must be resorted to with some tracking. 
Throughout this system from Monti Bay to the mouth of the An-kau many salmon 
were seen jumping. In the lower part of the An-kau redfish were very abundant on 
July 1, though the natives say there are more cohoes, which species they prefer for 
drying. With the spear the native is usually able to obtain all the fish he wants. 
See-tuck River . — The next river to the eastward is the See-tuck, which has its 
origin in two connecting lakes, and receives in its course tributaries having lake 
sources. The upper lake of the main stream lies near the head of Disenchantment 
Bay and about 1 mile from it, opposite the fourth glacier and across the mountain 
range bordering the western side of the bay. It is 190 feet above the sea and lies 
in a basin whose walls rise from 500 to 2,000 feet. It is 1% miles in length in a SE. 
direction, 200 yards to 700 yards wide, and had water of a greenish color, with a 
temperature of 45.5° F. on July 3. At the head is the main feeder, about 20 feet 
wide and 1 foot deep, flowing with a strong current a clay-colored water from the 
melting snow. The lake also receives the waters from numerous rivulets around the 
border. At the southern end is an outlet connecting it with the lower lake. This 
stream is 20 feet wide, 2 feet deep, and flows with a very swift current over a rocky 
and bowlderous bed having in places small areas of sand and gravel. The water has 
a milky tinge, and on July 3 had a temperature of 45° F. It has but one rapid, with 
a drop of about 4 feet. It retains its narrow bed, except at a few points, where it 
broadens out into shallows. After meandering westerly for about 4 miles the stream 
enters the lower or main lake. 
This lake is circular, about 2 miles in diameter, and is 110 feet above the sea, and 
has clear water; temperature, July 3, 60° F. On the northern shore is a mountain 
about 2,500 feet high, and the eastern and western shores are covered with dead spruce 
and hemlock, caused, it is said, by a subsidence due to an earthquake in September, 
1899. The outlet is on the southern side, and is the See-tuck River, which at the 
head is 50 feet wide, 2 feet deep, with a strong current. It flows through a winding 
channel to the sea, distant in a direct line about 13 miles. The water is clear and 
has a temperature of 60° to 62° F. The bottom at first is rocky and bowlderous, 
quickly changing to gravel and finally to sand and mud, as the sea is reached. The 
banks are low and covered with brush, giving ample evidence of a much larger stream 
during periods of freshets. About one-third its length from the lake the river receives 
from the westward the On-klat, a small tributary said to have a lake source. Two
