Harriman State Park is a state park in eastern Idaho, United States.
 It is located on an 11000 acre wildlife refuge in the Greater Yellowstone Ecosystem and is home to an abundance of elk, moose, sandhill cranes, trumpeter swans, and the occasional black or grizzly bear.
 Two-thirds of the trumpeter swans that winter in the contiguous United States spend the season in Harriman State Park.
 The land was deeded to Idaho for free in 1977 by Roland and W. Averell Harriman, whose insistence that the state have a professional park managing service helped prompt the creation of the Idaho Department of Parks and Recreation in 1965.
 The park opened to the public in 1982.
 It is located in Fremont County, 3 mi south of Island Park, Idaho.
 Henry's Fork, a fly-fishing stream, winds through the meadows of Harriman State Park.
 In winter, many of its roads and trails are groomed for cross country skiing.

Mary Williamson Averell (July 22, 1851 – November 7, 1932) was an American philanthropist and the wife of railroad executive E. H. Harriman.
 Born in New York to a successful family, Averell married Harriman in 1879.
 Averell's father introduced Harriman to the railroad business.
 After Harriman's death, his wife was left with between $70 and $100 million.
 She became dedicated to philanthropy, donating the land that became Harriman State Park and largely funding the development of the controversial Eugenics Record Office.
 Averell had several children; her son, W. Averell Harriman became governor of New York and her daughter Mary Harriman Rumsey founded the Junior League.

The Clove Furnace Ruin in Arden, New York, United States, was a longtime smelting site for iron ore mined from nearby veins in what is now Harriman State Park.
 It is located on Arden Station Road just east of the New York State Thruway, and can easily be seen from the highway.
 It was built in 1854 by Robert & Peter Parrott, who also owned and operated numerous mines in the area, known collectively as the Greenwood Iron Works.
 Together with the Greenwood Furnace (c.1810), located roughly one half mile east of Clove, these two furnaces produced iron which supplied the Parrott's West Point Foundry at Cold Spring, NY.
 The foundry produced the famous and highly effective Parrott Rifle (cannon) utilized by the Union army during the Civil War.
 The furnace shut down permanently, shortly after Robert Parrott's death in 1877.

Arden Valley Road is a scenic road located in Southfields, New York, in the United States, that travels through Harriman State Park and is owned by the Palisades Interstate Park Commission.
 At 5.2 mi long, it begins at New York State Route 17 (NY 17) in Southfields and ends at Seven Lakes Drive in Harriman State Park.
 Arden Valley Road also serves a trout stocking area for the Ramapo River.
 The road is located entirely in Orange County and is home to the Elk's Pen Trailhead in Harriman State Park.
 In 1921, plans arose by the commission to construct the road, which was completed the same year and stretched along the borderline with the Harriman estate.
 Major William A. Welch ordered 75 elk from Yellowstone National Park to be placed in a wired cage between Arden and Southfields in 1919.
 The elk eventually disappeared from the pen by 1942, and the area became the current Elk's Pen trailhead for trails within Harriman State Park.
