FISH-CULTURAL INVESTIGATIONS IN MONTANA AND WYOMING. 
7 
August 11. Traveled 16 miles up the Firehole River, across the Divide and to the outlet of Shoshone 
Lake, where we made our fifth camp. 
August 12. Shoshone Lake to Lewis River, below the upper falls, 10 miles. 
August 13. Lewis River across Crawfish Creek near Moose Falls to President Camp, on Snake River, 
20 miles. 
August 14. Crossed Snake River and proceeded southward to Jackson Lake, 12 miles. 
August 15. Turned eastward and camped on Pacific Creek, 12 miles from Jackson Lake. 
August 16. Followed up Pacific Creek 18 miles, where we again camped. 
August 17. Followed on up Pacific Creek 7 miles to Two-Ocean Pass, where we spent the day. 
August 18. Followed down Atlantic Creek to its mouth, crossed the Upper Yellowstone River, and 
camped on Thoroughfare Creek, 12 miles. 
August 19. Traveled 18 miles to the mouth of the Upper Yellowstone River, camping near the mouth 
of Beaverdam Creek. 
August 20. Traveled along east side of Yellowstone Lake 10 miles to the mouth of Meadow Creek. 
August 21. Followed on down east shore of the lake to the Yellowstone River, crossed over, and went 
up to Lake Hotel for mail, the rest of the party camping at mouth of Pelican Creek. 
August 22. Proceeded down Yellowstone River to the Grand Canon. 
August 23. I left the party here and went across the country to the Norris Basin, from which place I 
accompanied Mr. R. R. Cummins to Horsethief Springs, about 42 miles west. The rest of the 
party proceeded down Yellowstone River to the foot of Mount Washburn, where they camped. 
August 24. Examined Horsethief Springs and returned to Norris Hotel. The main party traveled on 
to Blacktail Deer Creek. 
August 25. All members of the party reached Mammoth Hot Springs at noon. 
August 26. Rode to Reese Creek above Cinnabar. Took the train in the evening, Prof. Jenkins and 
Mr. Clapham stopping off at Fridley’s to examine Botteler Springs, while I went on to Bozeman. 
August 27. Examined streams about Bozeman. Returning to Livingston that night, I was joined 
there by Prof. Jenkins and Mr. Clapham, and we took the train for the east. 
PHYSICAL FEATURES OF THE REGION EXAMINED. 
The desirability of reaching as many places as possible in the investigations 
pertaining to the selection of a site for the hatchery required ns to cover a much wider 
area in the season’s work than would otherwise have been advisable. Nothing like a 
thorough survey of the entire region traversed was possible in the time which we had 
to devote to it. 
In the measurement of the streams, the widths and depths given are the average 
for the distance through which we measured the current. The rate of the current was 
obtained by timing a floater, and the rate given is usually the average of the results of 
several tests. Usually the floater was timed for a distance of 50 to 100 feet. The 
measurements taken were under rather than over; hence the volume determined for 
each stream is believed to be slightly under the exact amount. The volume given is 
the number of gallons the stream discharges per minute. 
The temperatures were taken with one of Wilder’s standard Fahrenheit thermome- 
ters, and, unless otherwise stated, the temperature given is that of the water near the 
surface. The seining was done with two Baird collecting seines, one 15 feet, the other 
30 feet long. 
According to Dr. Hayden,* Montana is separated into two very unequal areas 
by the dividing range of the Rocky Mountains, which forms the southwestern bound- 
ary from the west line of Wyoming to the intersection of 45° 40' north latitude and 
the 114th meridian. Here it suddenly bends eastward for some distance, and then 
runs north about 20° west to the northern boundary of the State. Extending from
