Island Park, Idaho, is one of the best getaway destinations in the Mountain West. After all, that’s why you’re here, right? But what do you know of Island Park? Let’s dive in to what the park is and how it came to be. 

How Island Park Was Made

Island Park is actually a lot like Hawaii in the sense that both were formed by volcanic activity. Millions of years ago, hot magma under the earth pushed up skyscraping volcanoes out of the ground. These volcanoes regularly erupted until the hot magma was no longer underneath them. Many of the tall buttes southwest of Island park were formed in this way. However, massive eruptions in the Island Park area created circular valleys called a calderas. These calderas, some of the largest in the entire world, are what now form the mountainous walls of Island Park and Yellowstone National Park. 

Who First Lived in Island Park?

Island Park was traversed by Blackfeet, Bannock, Shoshone and Sheepeater Native Americans for thousands of years. However, none of these tribes held any permanent settlements in Island Park, as the area receives a lot of snow in the winter, making year-round living difficult. Native Americans would continue to pass through Island Park up until the late 1800s. 

Between 1810 and 1840, the Island Park area was dominated by mountain men looking for beaver furs, of which they obtained hundreds of thousands in the areas. Following the decline in the fur trade, ranching and tourism became the main use of Island Park. Even today, ranching cattle and recreational tourism are still the central means of occupation for Island Park residents, especially near Henry’s Lake. 

One of the largest cattle ranches in Island Park was that of the Herriman family, owned by Edwin Herriman, president of the Union Pacific railroad. He was one of many industrial barons from the East Coast that gained a fondness for the Yellowstone and Island Park areas of the Mountain West. Like other generous landowners who would come to build summer homes and businesses in Island Park, the Herriman family eventually gifted much of their land for recreational use. 

Another businessman-turned-philanthropist was A. S. Trude, a lawyer from Illinois who came through the area after touring Yellowstone National Park. It was Trude who helped establish the first conservation efforts within Island Park. Before he died, he gave his land to the Federal Government. The land was flooded according to his wishes, creating the beautiful Island Park Reservoir. 

In the century since Island Park was settled, millions have come to love the land. Visitors like yourself return many times, year after year, to enjoy the natural, wild beauty of the park. If this is your first Island Park experience, we hope that it won’t be your last.
