Question: The Thoen Stone is on display at a museum in what county?

full_context: Document 1: Thoen Stone: The Thoen Stone is a sandstone slab dated 1834 that was discovered in the Black Hills of South Dakota by Louis Thoen in 1887. The discovery of the stone called into question the first discovery of gold and the history of gold mining in the Black Hills; it would mean that gold was discovered in the Black Hills 40 years before the Custer Expedition of 1874 and the subsequent Black Hills Gold Rush. It is currently on display at the Adams Museum & House in Deadwood, South Dakota.
Document 2: Deadwood (TV series): Deadwood is an American western television series created, produced, and largely written by David Milch, that aired on the premium cable network HBO from March 21, 2004, to August 27, 2006, spanning 36 episodes and three seasons. The series, set in the 1870s in Deadwood, South Dakota, before and after the area's annexation by the Dakota Territory, charts Deadwood's growth from camp to town, incorporating themes ranging from the formation of communities to western capitalism. The show features a large ensemble cast, and many historical figures appear as characters, such as Seth Bullock, George Crook, Wyatt Earp, E. B. Farnum, George Hearst, Wild Bill Hickok, Calamity Jane, Jack McCall, Sol Star, Al Swearengen, and Charlie Utter. The plot lines involving these characters include historical truths as well as substantial fictional elements. Milch used actual diaries and newspapers from 1870s Deadwood residents as reference points for characters, events, and the look and feel of the show. Some of the characters are fully fictional, although they may have been based on actual persons.
Document 3: AVM Runestone: The AVM Runestone, also known as the Berg-AVM Runestone, is a hoax created in 1985 by students carving runes into a boulder near Kensington, Minnesota, not far from where the Kensington Runestone was found in 1898. In 2001, a carving expert and her geologist father found the AVM Runestone, told the press that it was proof of early Viking or Norse settlement in Minnesota, and began an investigation to prove its authenticity. The creators came forward with their story that it was purely a hoax and not an artifact of Viking explorers.
Document 4: Ardjachie Stone: The Ardjachie Stone is an uncut but decorated red sandstone boulder discovered by farmers in 1960 on the Ardjachie Farm in the Tarbat peninsula of Easter Ross. It now stands outside of the museum of Tain. On it are depicted several dozen cup or ring marks probably dating to the Bronze Age. It also has an inverted-L design with a wheel image above, both of probable Pictish origin. It therefore may be considered a Class I Pictish stone.
Document 5: Adams Museum &amp; House: Adams Museum & House, The Historic Adams House was built in 1892 by Deadwood pioneers Harris and Anna Franklin. The elegant Queen Anne-style house heralded a wealthy and socially prominent new age for Deadwood, a former rough and tumble gold mining town. Its the oldest history museum in the Black Hills and ranks #3 among True West magazine's 2009 Top 10 Western Museums. Artifacts and displays from Deadwood's historic past reflect the powerful legends of infamous characters like Wild Bill and Calamity Jane. In 1920 Deadwood businessman and former mayor W.E. Adams brought the house as a tribute to the Black Hills pioneers and in remembrance of his deceased first wife and two daughters. The museum was a gift to the city of Deadwood and it remains city property to this day. It is located at 54 Sherman Street.
Document 6: Yarmouth Runic Stone: The Yarmouth Runic Stone, also known as the Fletcher Stone, is a slab of quartzite that first came to the attention of the public in the early 19th Century. The stone appears to have an inscription carved into it, which some investigators, notably Henry Phillips, Jr., have interpreted as Norse runes. This has led to speculation that the Yarmouth, Nova Scotia area, in Canada, was visited by Viking explorers sometime around 1000 C.E. Many other theories have been put forward, including the possibility of a hoax or the inscription being a product of natural forces. The Stone is currently on display at the Yarmouth County Museum.

When South Dakota's 3rd congressional district was eliminated after the 1930 Census, the 2nd District was relocated to cover all of the counties in South Dakota west of the Missouri River.
