2019-S Idaho Frank Church River of No Return Wilderness Quarter GEM SILVER PROOF America the Beautiful

The Frank Church-River of No Return is a wilderness of steep, rugged mountains, deep canyons, and wild, whitewater rivers. The Salmon River Mountains, located south of the Main Salmon and west of the Middle Fork, are the most massive range, and dominate the Wilderness. North of the Main Salmon River are the Clearwater Mountains, east of the Middle Fork are the Bighorn Crags. The Salmon River Canyon is one of the deepest gorges in North America, deeper even than the famous Grand Canyon of the Colorado in Arizona. But in contrast to the Grand Canyon, the Salmon River Canyon is not noted for sheer walls and towering heights, but instead for the variety of landscapes visible from the river; wooded ridges rising to the sky, huge eroded monuments and bluffs and slides, picturesque castles and towers, and solitary crags. The United States Congress designated the Frank Church-River of No Return Wilderness in 1980 and it now encompasses a total of 2,366,757 acres. Administration of the wilderness is accomplished by two Forest Service Regions (Northern and Intermountain), and four National Forests, the Salmon Challis, Payette, Nez Perce, and Bitterroot. It is the largest contiguous wilderness in the Lower 48 and the second largest unit of the National Wilderness Preservation System in the Lower 48 (second in size only to California’s Death Valley Wilderness). The lead forest for managing the coordination of the Wilderness is the Salmon-Challis National Forest, with headquarters located in Salmon, Idaho.

From 2010 through 2021 the US Mint is issuing commemorative quarters with special reverse designs celebrating National Parks and other National Sites. A park or site is being honored in each of the 50 States, the District of Columbia, and the five US Territories: Puerto Rico, Guam, American Samoa, US Virgin Islands, and Northern Mariana Islands. Each National Park or National Site was selected for its natural or historical significance. The National Park Quarters are being minted and issued at the rate of 5 designs a year, in approximately ten week intervals. The National Park Quarters are being released in the order that the locations were first designated as National Sites. The Obverse side of the coins feature a smaller restoration of the original Washington Quarter portrait, modeled from designer John Flanagan's 1932 plaster. The Reverse of each coin will feature a representation of the unique character and environment of each State, District, or Territory's National Park or Historic Site.

Circulation strikes will be minted at the Philadelphia (P) and Denver (D) Mints (starting in 2012 circulation strikes were also minted at the San Francisco (S) Mint). The San Francisco (S) mint will strike the Proofs in clad composition and silver. Clad composition strikes contain an outer layer of 75% copper and 25% nickel bonded to an inner core of pure copper with a 24.33 mm diameter, 5.67 grams weight, and a reeded edge. Up until 2019, the silver strikes were minted from 90% silver and 10% copper with a weight of 6.25 grams. Beginning in 2019 the mint began striking these coins in 0.999 silver.
