President Calvin Coolidge signs legislation establishing the 96,000 acres (390 km2) Grand Teton National Park in Wyoming.

Calvin Coolidge was the 30th president of the United States, serving from 1923 to 1929. A Republican lawyer from Massachusetts, he previously served as the 29th vice president from 1921 to 1923 under President Warren G. Harding, and as the 48th governor of Massachusetts from 1919 to 1921. Coolidge gained a reputation as a small-government conservative with a taciturn personality and dry sense of humor that earned him the nickname "Silent Cal".

Grand Teton National Park is a national park of the United States in northwestern Wyoming. At approximately 310,000 acres (1,300 km²), the park includes the major peaks of the 40-mile-long (64 km) Teton Range as well as most of the northern sections of the valley known as Jackson Hole. Grand Teton National Park is 10 miles (16 km) south of Yellowstone National Park, to which it is connected by the John D. Rockefeller Jr. Memorial Parkway. Along with surrounding national forests, these three protected areas constitute the almost 22-million-acre (89,000-square-kilometer) Greater Yellowstone Ecosystem, one of the world's largest intact mid-latitude temperate ecosystems.

Wyoming is a landlocked state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With an estimated population of 587,618 as of 2024, Wyoming is the least populous state despite being the 10th largest by area, and it has the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had a population of 65,132 in 2020.
