ITINERARY OF THE ROUTE FROM FORT VANCOUVER TO FORT DALLES. 
Crossed a rivulet. 2J 
Encamped on a small prairie ; good grass; water inconvenient; camp to camp 
eight and a half hours. i 
July 25.—To camp Yahkohtl. Country becoming rougher; obstructions on the 
trail, principally from dead timber ; descended a very steep hill, with a small 
stream at the foot, a branch of the Yahkohtl..... 3£ 
Crossed a rough divide, and descended a long and steep hill to Yahkohtl river.. 1^ 
Passed over a rolling country, with open woods on the higher portion; thick 
brush in the bottoms; camped on the edge of Yahkohtl prairie; soil and grass good; 
good water in running stream close to camp. 5 
July 31.—To camp Chalacha. Country rolling; some short, steep hills; dense 
underbrush and timber; many fallen trees; crossed five streams... 2f 
Crossed another, but smaller stream.. 2 
Travelled up the prairie and encamped. Good water and grass. f 
August 1.—To camp Spilyeh. Country rolling and heavily timbered with fir, 
oak, white maple, and cedar; crossed small rivulet in a deep ravine. 1 
Crossed four small plains covered with fern to the height of the head of a 
mounted man ; commenced descent into the valley of Cathlapoot’l. 3 
This descent is long, steep and dangerous; the trail winding down the narrow 
crest of a ridge, with a precipitous descent on each side. Here we lost a mule, 
killed by falling over the steep side-slope. At the foot of the descent a small spring 
branch, sandy bottom, of half a mile, and cross Cathlapoot’l. l£ 
Pass over rough and thickly timbered country ; cross Spilyeh creek. 2£ 
Travel over a similar country, and camp in a plain one mile long; grass and 
water good... 2J 
August 2.—To camp Lakas. Country level and open, but much heavy fallen 
timber; cross small stream. 2f 
Pass through small plain, covered with fern; descend steep hill and touch Cath¬ 
lapoot’l . 2^ 
Follow valley of the stream, over stony beach; current rapid ; bottom of large 
stones. ii 
Follow left bank of the stream, and encamp in the woods ; no grass. £ 
Arigust 3.—To camp Noompt-nah-mie. Crossed the river a few hundred yards 
above camp. During the march crossed one fine stream, coming in on the right 
bank, three miles from camp; afterwards three spring branches; trail keeps near 
the river; heavy brush; in one spot a fine grove; country barren; passed over a 
tract of lava three quarters of a mile in length; crossed the Noompt-nah-mie near 
its mouth, and encamped at the crossing; no grass; crossing difficult in low water; 
impossible in high water... 
August 4.—To camp Wininepat. Crossed a high, narrow ridge, with steep 
ascent and descent; small brook at its foot on north side; pass through open woods 
of fir, cedar, maple, and alder; crossed another rivulet, and then crossed the Cath¬ 
lapoot’l; followed the stony beach half a mile, and recrossed. 2J 
The trail passes through a small opening, and then a new trail was cut through 
the thick brush and fallen timber for about two miles, to avoid a very deep crossing;
