Field Notes from the Platte River Road

Use a historian's notes and rainfall data to explain how geography shaped trails, Plains settlement and Native nations' lands.

Along the trail

Read the field notes and the table. The historian and her notes are invented; the places, dates and history are real.

Field Notebook of Dr. Teresa Halvorsen, Historian

1Stop 1, Independence, Missouri. This was a main starting point for the Oregon Trail, which ran about 2,000 miles to Oregon's Willamette Valley. Historians estimate that roughly 400,000 people traveled the Oregon, California and Mormon trails between the 1840s and 1869. Most wagon trains left in April or May. A museum guide reminded me that in March the prairie grass here is still short and brown, and that oxen and mules ate grass all the way west.

2Stop 2, the Platte River near Kearney, Nebraska. The Platte is wide and shallow, braided into channels around sandy islands. The valley floor is flat and grassy for miles, and the few trees grow mostly on the islands. Wagon trains followed this river for hundreds of miles. This valley was also the homeland of the Pawnee, who farmed corn, beans and squash near their earth-lodge villages and hunted bison on the plains. As wagon traffic grew, travelers' animals ate the grass and travelers cut the scarce wood. In the 1870s, the United States moved the Pawnee to Indian Territory. The Pawnee Nation's government is based today in Pawnee, Oklahoma.

3Stop 3, Scotts Bluff, Nebraska. Huge clay and sandstone bluffs rise from the plain, and travelers used them as landmarks. Out here there are almost no trees. At a rebuilt homestead I saw a house made of blocks of prairie sod, a windmill that pumped water up from deep underground, and a fence of barbed wire, which was invented in the 1870s. Under the Homestead Act of 1862, a family could claim 160 acres of public land if they lived on it and farmed it for five years.

4Stop 4, Fort Laramie, Wyoming. In 1851, at Horse Creek, about 35 miles east of this fort, U.S. officials met with the Lakota, Cheyenne, Arapaho, Crow and other nations. The treaty set boundaries for each nation's lands and promised yearly payments; in return the nations agreed to let travelers pass and the army build roads and posts. Within a few years, more travelers, soldiers and later miners crossed these lands, and the Senate cut the promised payments. Lakota and Cheyenne families relied on the great bison herds, which shrank to perhaps a few hundred wild animals in the United States by the late 1880s. Today the Oglala Sioux Tribe, one of the Lakota nations, governs the Pine Ridge Reservation in South Dakota.

5Stop 5, South Pass, Wyoming. I expected steep peaks, but the pass is a broad, gentle valley about 20 miles wide, at roughly 7,400 feet above sea level. Wagons crossed the Continental Divide here without climbing a cliff. Snow can fall here as early as September. This is homeland of the Eastern Shoshone. Under the 1868 Fort Bridger Treaty, signed by Chief Washakie, the Wind River Reservation was set aside nearby; the Eastern Shoshone and the Northern Arapaho both live there today.

1.
Based on Stop 2, why did wagon trains follow the Platte River for hundreds of miles?
Question 1 options
2.
Use the table.

From Independence to South Pass, yearly rain and snow drop by about inches.

3.
Use Stops 1 and 5. Why did most wagon trains leave Independence in April or May, not in March or July?
Question 3 options
4.
Based on Stop 5, why did so many routes to Oregon and California cross the Rocky Mountains at South Pass?
Question 4 options

Settling the Plains

Use Stop 3 and the table.

5.
Draw a line from each Plains problem to the homesteaders' answer described at Stop 3.
6.
In 1875, a family claims 160 acres near Scotts Bluff. They come from Ohio, where about 40 inches of rain and snow fall each year. Based on the table, which problem would they most likely face?
Question 6 options

Native nations and the land

Use Stops 2, 4 and 5.

7.
Underline the sentence from Stop 4 that best shows the promises of the 1851 treaty were not kept.

8.
In the 1851 treaty, the United States wanted safe passage for travelers. What did the Lakota, Cheyenne and other nations most likely want from it?
Question 8 options
9.
Sort each statement: does it describe the 1800s or today?
10.
Which change in the notes most directly threatened the way of life of the Lakota and Cheyenne families described at Stop 4?
Question 10 options
11.
Claim: "The same geography that helped the wagon trains brought hardship to Native nations." Do you agree? Make your own claim, use at least two pieces of evidence from the notes or the table, and explain your reasoning.
