The Snake River is a big river. It flows through many states. It goes past high hills and deep canyons. Fish like salmon live in the water. It is a very special place. Do you like to see rivers?
The Snake River is a very big river. It starts in a park in Wyoming. Then it flows through Idaho and Oregon. It even goes into Washington.
The river flows through deep canyons. It also flows through dry plains. The water moves past high cliffs. It can move through rocky hills too.
Many fish live in the river. Salmon used to swim here in large groups. These fish swim from the ocean to the river. This is a long trip for them.
People have lived near the river for a long time. Some tribes used the fish for food. Later, many people came to find gold. They built dams to use the water.
Today, the river is still very important. It helps plants grow on farms. It is a grand place to see.
The Snake River is a very large river. It flows through the Pacific Northwest in the United States. The river starts in Yellowstone National Park in Wyoming. It travels through Idaho, Oregon, and Washington. It is the largest tributary of the Columbia River. A tributary is a smaller river that joins a larger one.
The river's path is full of changes. It flows through dry plains and deep canyons. Hells Canyon is one of the deepest canyons in North America. 
Fish and people are part of its story. Salmon used to swim in huge groups here. Many tribes lived by the river to fish for them. Today, people use dams to make power. 
The Snake River is a major river in the Pacific Northwest. It is the largest tributary of the Columbia River. A tributary is a smaller river that flows into a larger one. The Snake River is the twelfth largest river in the United States. It provides about one-fifth of the water that the Columbia River carries to the ocean. 
The river begins in the Rocky Mountains of Wyoming. It starts near the southern border of Yellowstone National Park. From there, it flows through the Teton Wilderness and Jackson Hole. The water travels through the dry Snake River Plain in Idaho. 
Many things changed the river over millions of years. Volcanic activity once covered the area with basalt rock. 


People have lived near the river for a very long time. Indigenous tribes like the Shoshone and Nez Perce used the salmon for food. 

Today, the river is still a very important place for nature. It is home to the longest sockeye salmon run in the world. 


The Snake River is a massive river in the interior Pacific Northwest of the United States. It is the largest tributary of the Columbia River. A tributary is a river that flows into a larger one. The Snake River is the twelfth largest river in the United States. It contributes about one-fifth of the total water that the Columbia River carries to the Pacific Ocean. This river is a vital part of the regional landscape and watershed. 
The river's path begins in the Rocky Mountains of western Wyoming. It starts north of Two Ocean Pass near the southern border of Yellowstone National Park. From the mountains, it flows through the Teton Wilderness and meets the Lewis River. It then enters Jackson Lake in Grand Teton National Park. The river meanders through the alpine valley of Jackson Hole. After passing the town of Jackson, it forms the Snake River Canyon of Wyoming. It eventually crosses into Idaho and travels across the arid Snake River Plain. 
Geological forces have shaped the river over millions of years. Long ago, volcanic activity covered much of the western watershed with Columbia River basalts. 

Human history along the river is long and complex. For thousands of years, indigenous peoples relied on the river for food. The Shoshone and Nez Perce were two of the largest tribes living there. 
In the 20th century, humans changed the river through engineering. Large irrigation projects were developed to turn the desert into farmland. This transformed south-central Idaho into a region known as the "Magic Valley." 
The river is famous for its dramatic scenery and deep canyons. Hells Canyon is one of the deepest canyons in North America. It is almost one-third deeper than the Grand Canyon. The canyon sits between the Rocky Mountains and the Blue Mountains. Within this canyon, the river flows through the Hells Canyon Wilderness. Many parts of the river corridor are only reachable by boat. The water features many Class III and IV rapids. 
Nature and policy are closely linked on the Snake River today. The river and its tributary, the Salmon River, host the world's longest sockeye salmon run. These fish swim from the Pacific Ocean all the way to Redfish Lake in Idaho.
