ALASKA SALMON INVESTIGATIONS IN 1901. 
385 
more tributaries are received from the westward and two from the eastward, along 
the middle third of its length, draining ponds and marshes. It is said that salmon 
spawn in these tributaries and their sources. About 2 miles from the sea the Ku-na- 
yosh, about half the size of the See-tuck, joins the latter from the eastward. It is 
said to cany many redfish. There are several small islands in the See-tuck, but no 
natural or artificial obstructions to prevent the free ascent of fish. 
Numerous king salmon and redfish and a few of the other species were seen in 
the river and a few redfish and one king salmon were seen jumping in the lakes. 
A hatchery site might possibly be found in the locality, but inaccessibility would 
probably be a bar to its successful operation. 
The mouth of the See-tuck is about 120 feet wide and 14 inches deep. It widens 
into a broad, sandy, tidal basin, full of bars, which connects with the sea by a channel 
having strong currents, in which it is said 6 feet can be carried at low water. This 
basin is connected, by a slough inside the coast line, with another tidal basin formed 
at the mouth of the Ahrn-klin, the next large stream to the eastward, and together 
they form an island called Black Sand Island. This slough is about 3 miles in length, 
60 to 200 yards in width, and 12 to 15 inches deep at low water, with a tidal current 
which enters at either end. It forms a connecting canoe passage along the coast. 
At high water a canoe can be tracked from the An-kau basin into the See-tuck basin, 
but at any other time of tide it is quicker to make a portage from one-half to three- 
fourths mile across the fiat from the An-kau basin to the See-tuck River proper, 
aiming to strike a point on the river where it leaves the tree line. No difficulty is 
experienced in passing from the See-tuck to the Ahrn-klin by the slough referred to. 
The Ahrn-klin is said to receive the main body of water from three sources. 
First from a lake on the western foot of Yakutat Glacier, which is grayish in color, 
cold, and deep, and receives part of the drainage from the glacier. The outlet, after 
flowing to the southwest about 4 miles, is joined by a stream from the northward, of 
equal length, draining Moser Glacier; they flow together about 4 miles and form a 
junction with a stream flowing from the northwest, which is the outlet to a clear lake, 
about 3 miles southeast from Disenchantment Bay, which is said to be about 1 mile 
long, three-fourths mile wide, and to form a favorite spawning-ground. 
There are several other small tributaries, some of which have clear water and 
drain ponds and small lakes, but none of importance. 
The general course of the Ahrn-klin system is a little to the westward of south 
until within a mile of the coast, when it turns abruptly to the westward and follows 
the coast just inside a sand bar, where it forms a tidal basin. This basin is full of 
bars and strong currents, from which a channel, in which it is said 6 feet may be 
carried at low water, leads to the sea at the eastern end of Black Sand Island. 
The Ahrn-klin is slightly larger than the See-tuck and is similar in its general 
characteristics, except that the water is glacial in color. Temperature, 51° F. 
The mouths of the See-tuck and Ahrn-klin, as well as the connecting slough, 
were full of jumping salmon. It is said that king salmon, redfish, and cohoes ascend 
the Ahrn-klin, but that the See-tuck carries more redfish. The natives say they have 
taken 10,000 redfish from the See-tuck; if this is true, the stream must have a large 
fish value, as the natives have only very primitive appliances and take only sufficient 
for their wants. The fact is that the value of these streams is entirely unknown, as 
the natives obtain all the fish they want from the streams near their villages; and as
