Question: What medium-sized bear native to North America can be seen in Harriman State Park?
Context: The American black bear ("Ursus americanus") is a medium-sized bear native to North America. 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. Grassy Point (formerly known as North Haverstraw), was a hamlet on the west side of the Hudson River, in the Town of Stony Point in Rockland County, New York, United States.  It was located north of West Haverstraw; east of Harriman State Park; south of Stony Point. Lake Welch Parkway, sometimes labeled Lake Welch Drive, is a scenic road located within Harriman State Park in southern New York in the United States.  It extends for 5.60 mi on a southwest–northeast alignment from an intersection with Seven Lakes Drive to a partial interchange with the Palisades Interstate Parkway.  The highway is located entirely in Rockland County, although it runs close to the border with Orange County.  It is inventoried by the New York State Department of Transportation as New York State Route 987A (NY 987A), an unsigned reference route; however, it is owned by the Palisades Interstate Park Commission.  The portion of Lake Welch Parkway that lies south of Tiorati Brook Road is closed during the winter. 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. At 47527 acre , Harriman State Park is the second largest state park in New York.  Located in Rockland and Orange counties 30 mi north of New York City, it is a haven for hikers with over 200 mi of hiking trails.  The park is also known for its 31 lakes, multiple streams, public camping area, and great vistas.  The park's hiking trails are currently maintained by volunteers from the New York - New Jersey Trail Conference. At 310 acre , Lake Sebago is the largest lake in Harriman State Park in the U.S. state of New York.  The name is Algonquian for "big water".  Operated by the Palisades Interstate Park Commission, Lake Sebago is surrounded by picnic lawns and play fields, and is popular with anglers fishing for landlocked salmon, lake trout, bass, perch and sunfish.  The lake has a swimming beach, hand boat launch (electric motors only) and cabin camping.  Lake Sebago lies near Sloatsburg.  It is located just south of Lake Kanawauke and is accessible by auto from Seven Lakes Drive. 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. Pomona is a village partly in the town of Ramapo and partly in the town of Haverstraw in Rockland County, New York, United States.  It is located north of New Hempstead, east of Harriman State Park, north of Monsey and west of Mount Ivy.  According to the 2010 Census, the population was 3,103, a 13 percent increase from the 2000 figure of 2,726. 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.
