parently a part of the same range, are the well known Jocko peaks, shown 
in the illustration from the mountain summit, Plate XXI. 
The range extends almost due north and south, the meridian 387 pass- 
ing along the western base of the range. The 46th and 47 parallel 
degrees approximately mark the southern and northern ends, though a 
large bend extends toward the east in the southern end of the range. 
The drainage from the western side is across the Flathead Reserva- 
tion, through several creeks, into the Pend d’Oreille river, and into 
Clarke’s Fork of the Columbia. The drainage from the eastern side is 
into the Swan river, north around the range into Flathead lake, and out 
through the Pend d’Oreille river as before. From the southern end the 
waters are carried by the Jocko river into the Pend d’Oreille river. A 
portion of the eastern slope of Sinyaleamin mountain, as also the east- 
ern slopes of the Jocko peaks, drains into the Clearwater river, thence 
into the Big Blackfoot; from this into the Missoula, and finally into 
Clarke’s Fork of the Columbia. It is thus seen that the entire drainage 
of the range is into the same stream, though by very different routes, 
and over distances of varying lengths. 
SINYALEAMIN LAKE. 
The first place in the range at which work of consequence was un- 
dertaken was at Sinyaleamin lake. See plates XXII and XXIII. As has 
been stated, this little alpine lake is at the southern base of Sinyaleamin 
mountain. From the nature of the location of the lake the name is very 
appropriate. Locally the lake is called St. Mary lake. As there is an- 
other larger and more widely known St. Mary lake in the northern part 
of the state in the Blackfeet reservation, the name Sinyaleamin lake is 
most appropriate for this beautiful little sheet of water, and should be re- 
tained. 
St. Ignatius is about six miles from Selish, on the Northern Pacific 
railroad. From St. Ignatius to Sinyaleamin lake the distance is given 
as nine miles. The distance to the mouth of the canyon is nearly six 
miles and the road up the winding canyon is about three miles. The road 
across the valley is excellent. A mountain road has been constructed up 
the canyon to the lake. This is passable in summer, is no doubt 
good in winter, and with a little work could be made very good indeed, 
save for a couple of steep hills. The road follows up the canyon carrying 
the waters from Sinyaleamin lake. This stream joins the main stream 
before it reaches the Mission. The waters from the branch stream ara 
derived almost wholly from Sinyaleamin lake. The waters from the 
main stream of the Mission creek come from the mountain peaks to tha 
north of Sinyaleamin mountain, tumbling over a high fall which may be 
seen miles away on the plain. 
The lake is hemmed in on all sides by mountains, only a small flat 
near the water affording a camping site. This camping site is on the top 
of an old moraine which is well covered with small timber. If the tim- 
ber was cleared away there would be a good-sized camping site in an 
admirable location for scenery. Campers are continually widening the 
small space by cutting down small trees for fuel and it is now a de. 
lightful place for a camp for either outing or study.
