Question: Adolph Sutro made a fortune at a silver ore located under the eastern slope of what mountain?
Context: Mount Olympus is a hill located on Upper Terrace in the Ashbury Heights neighborhood of San Francisco.  It was once considered to mark the geographical center of the city, and was topped off by a statue given by Adolph Sutro, the "Triumph of Light", now lost.  Only the statue's pedestal remains, and the view from the top is obstructed by trees and condominiums. Silver King Camp is a ghost town located in the West Kootenay region of British Columbia.  The town is located on Toad Mountain near Nelson and was founded in the 1880s.  In 1887 silver ore was discovered on Toad Mountain, and a mine was created called the Silver King which was owned by the Hall family of Nelson.  A town grew around the workings of the mine.  By 1898 Silver King Camp had a population of 190.  The Silver King mine was the greatest shipper of silver ore to the Nelson Smelter for two decades.  A forest fire destroyed Silver King Camp and today little remains of the town. The Comstock Lode is a lode of silver ore located under the eastern slope of Mount Davidson, a peak in the Virginia Range in Nevada (then western Utah Territory).  It was the first major discovery of silver ore in the United States. Stockland Castle is the name given to two Iron Age hill forts on Stockland Hill close to Stockland in Devon, England.  Stockland Great Castle ( ) occupies a position on the eastern slope of the hill at 190 - above sea level.  Stockland Little Castle ( ), located about 1 km northeast of its larger neighbour, occupies a small promontory on the eastern slope of the hill at approximately 175 m above sea level. Cerro Rico (Spanish for "rich mountain"), Cerro Potosí ("Potosí mountain") or Sumaq Urqu (Quechua "sumaq" beautiful, good, pleasant, "urqu" mountain, "beautiful (good or pleasant) mountain") is a mountain in the Andes near the Bolivian city of Potosí.  Cerro Rico was famous for providing vast quantities of silver for Spain during the period of the New World Spanish Empire.  The mountain, which is popularly conceived of as being "made of" silver ore, caused the city of Potosí to become one of the largest cities in the New World.  After 1800, the silver mines were depleted, making tin the main product.  This eventually led to a slow economic decline.  Nevertheless, the mountain continues to be mined for silver to this day.  Due to poor worker conditions, such as a lack of protective equipment against the constant inhalation of dust, many of the miners contract silicosis and have a life expectancy of around 40 years.  The mountain is still a significant contributor to the city's economy, employing some 15,000 miners. Alfred Sutro OBE (7 August 1863 – 11 September 1933) was an English author, dramatist and translator.  In addition to a succession of successful plays of his own in the first quarter of the 20th century, Sutro made the first English translations of works by the Belgian writer Maurice Maeterlinck. SS "Comet" was a steamship that operated on the Great Lakes.  "Comet" was built in 1857 as a wooden-hulled propeller-driven cargo vessel that was soon adapted to carry passengers.  She suffered a series of maritime accidents prior to her final sinking in 1875 causing the loss of ten lives.  She became known as the only treasure ship of Lake Superior because she carried 70 tons of Montana silver ore when she sank.  The first attempts to salvage her cargo in 1876 and 1938 were unsuccessful.  "Comet" was finally salvaged in the 1980s when the Great Lakes Shipwreck Historical Society illegally removed artifacts from the wreck.  The artifacts are now the property of the State of Michigan and are on display as a loan to the Great Lakes Shipwreck Museum.  The fate of her silver ore cargo is unknown.  "Comet"' s wreck is now protected by the Whitefish Point Underwater Preserve as part of an underwater museum. Ott's Assay Office is a historic assay office located at 130 Main Street in Nevada City, California.  The building was constructed in 1851 as a drug store; James J. Ott opened his assay office in the back of the store in 1857.  In 1859, Ott assayed a sample of silver ore discovered in the Washoe Country; this ore marked the discovery of the Comstock Lode, and the resulting silver rush eventually led to Nevada's statehood and several advancements in mining technology.  The silver rush also gave Ott a reputation as a quality assayer; he ran his office until his death in 1907, and his son continued the business until 1955. Adolph Heinrich Joseph Sutro (April 29, 1830 – August 8, 1898) was a German-American engineer, politician and philanthropist who served as the 24th mayor of San Francisco from 1895 until 1897.  Born a German Jew, he moved to Virginia City, Nevada and made a fortune at the Comstock Lode.  He is today perhaps best remembered for the various San Francisco lands and landmarks that still bear his name. Berggeschrey or Berggeschrei ("mining clamour") was a German term for the rapid spread of news on the discovery of rich ore deposits that led to the rapid establishment of a mining region, as in the silver rush in the early days of silver ore mining in the Ore Mountains.  It is similar in some respects to the gold rush in North America.
