History of Idaho Falls
How Idaho Falls Began
Idaho Falls started as a place called Taylor’s Crossing in 1864. It was named after a man named Matt Taylor. He built a wooden bridge across the Snake River in 1865. This bridge helped people travel west on the Montana Trail. It was safer than the ferry that was used before.
The bridge made it easier for settlers, miners, and traders to reach places like Bannack and Virginia City. These towns in Montana were famous for their gold.
From Eagle Rock to Idaho Falls
By 1866, the town was known as Eagle Rock. This name came from a small island in the Snake River. Many eagles used to nest there. Before the bridge, a ferry also operated at this spot. So, the area was already known as Eagle Rock. The town grew with a bank, a hotel, and a place for horses.
In 1879, the Utah and Northern Railway (U&NR) came to Eagle Rock. The railroad built a new iron bridge across the Snake River. This bridge was 800 feet (244 meters) long! The railroad helped the town grow even more. Many settlers came to the Upper Snake River Valley. They started farms and built irrigation canals. These canals brought water from the Snake River to turn dry land into green farms.
In 1891, the town changed its name to Idaho Falls. This new name came from the fast-moving water, or rapids, below the bridge. Later, a power plant was built, which made the rapids look more like waterfalls. By 1895, a huge irrigation canal, called the Great Feeder, helped turn thousands of acres into farmland. The area became known for growing crops like sugar beets, potatoes, and grains.
Nuclear Research and Innovation

In 1949, the Atomic Energy Commission opened a special research center. It was called the National Reactor Testing Station. This center was in the desert west of Idaho Falls. On December 20, 1951, something amazing happened there. A nuclear reactor produced useful electricity for the first time ever! More than 50 different nuclear reactors have been built and tested at this site.
The site was also where the only fatal nuclear reactor accident in U.S. history happened. This was on January 3, 1961. It happened at an experimental reactor called SL-1. Due to a mistake, a control rod was pulled too far out. This caused the reactor to quickly get too hot. The water inside the reactor boiled very fast. This created a strong pressure wave. Three men were working in the reactor room. Sadly, all three men died from their injuries. The reactor core melted, but it did not cause damage to the surrounding area. This event led to better safety rules for nuclear reactors.
Today, the site is known as the Idaho National Laboratory (INL). It is a very important place for the city. More than 8,000 people work there. It is a world-famous research center. The INL also operates the Advanced Test Reactor (ATR).
Geography and Nature
Idaho Falls covers about 24.55 square miles (63.59 square kilometers). Most of this area is land. Natural disasters are rare here. However, a strong tornado hit the area in 1978.
River Walk Trail
Idaho Falls has a beautiful river walk trail. It runs for several miles along the Snake River. You can run or bike on the trails. There are also art displays and interesting spots to see. The city takes care of the river walk.
Idaho Falls Neighborhoods
Idaho Falls has several unique neighborhoods:
- Downtown is the historic heart of the city. It has restaurants, shops, and cultural places. You can visit the Museum of Idaho and the Colonial Theatre here. The Idaho Falls Farmers' Market is also held downtown.
- The Numbered Streets area was the first planned neighborhood. The streets run east and west. You can find Kate Curley Park and the Wesley W. Deist Aquatic Center here.
- West Side is where the Idaho Falls Regional Airport is located. It has a more small-town feel.
- Snake River Landing is a newer area on the west side. It has homes, restaurants, parks, and event spaces. It hosts the big Melaleuca Freedom Celebration on Independence Day.
Climate
Idaho Falls has warm summers and cold winters. It doesn't get a lot of rain or snow, but enough to not be considered a desert.
