The following map shows three possible trails you could take to reach Fort Bridger. Choose the trail you think is the best. Give reasons why you chose that trail over the other two options.

Idaho

WYOMING Bighorn Mts.
You are here

Snake River

Rocky Mts.

Utah
Green River = Mountains = Fort Bridger

Platte River

Laramie Mts. Colorado Trail A KEY Trail B Trail C Shoshone Village

Sample Response

I chose Trail C because it had fewer obstacles. Trail A has too many mountains to cross, and there are Indians that may or may not be friendly. On trails A & B you have to cross the Platte River twice.That might be hard for the horses and wagons. That’s why I chose Trail C .

Idaho

WYOMING Bighorn Mts.

Snake River

Rocky Mts.

Utah Laramie Mts. Green River

Platte River

Colorado
