Mormon Island was once a mining town, which had an abundance of Mormon immigrants seeking gold in the American River during the California Gold Rush. Its site is in present-day Sacramento County, California.
Early in March 1848, W. Sidney, S. Willis, and Wilford Hudson, members of the Mormon Battalion, set out from Sutter's Fort to hunt deer. Stopping on the south fork of the American River, they found gold. They told their story on returning to the fort, and soon about 150 Mormons and other miners flocked to the site, which was named Mormon Island. This was the first major gold strike in California after James W. Marshall's discovery at Coloma. The first ball in Sacramento County was held there on December 25, 1849.
The population of the town in 1853 was more than 2,500. It had four hotels, three dry-goods stores, five general merchandise stores, an express office, and many small shops. R. C. Chambers had moved to Mormon Island in July 1850, prior to his mining successes in Montana and Utah.[2]
A fire destroyed the town in 1856, and it was never rebuilt. The community dwindled after the California gold rush and only a scattered few families were left in the 1940s.
What was left of Mormon Island was eventually razed, as the Folsom Dam project was set to flood the town. The only visible remnant of this community is Mormon Island Cemetery,[3][4] a relocation cemetery located south of the lake on the dry side of Mormon Island Dam (off of Green Valley Road in Folsom, California). The cemetery also contains remains exhumed from other cemeteries that were inundated by the creation of Folsom Lake as well as relocated graves from Prairie City which were unearthed during construction of an on-ramp to U.S. Route 50 from Prairie City Road.
モルモン島は現在、カリフォルニア州歴史的建造物第569号として登録されています。[ 1 ]以前の場所はフォルサム湖の下にあるため、歴史的標識はフォルサム湖州立レクリエーションエリアのフォルサムポイントピクニックエリアに設置されています。[ 1 ]
この「島」は、アメリカ川によって西側、北側、東側が形成され、南側は人工運河によって形成されました。この運河は、川底の奥深くにある金鉱を発見するために、水路を迂回させるために利用されました。時が経つにつれ、町の大部分はこの場所の南側に形成されました。[ 5 ]
湖の水位が非常に低いときには、建物の基礎部分やアーチ橋が見えることがあります。2012年から2014年にかけての北米干ばつにより、フォルサム湖の水位が記録的な低水位となった2013年末から2014年初頭にかけて、町の郊外の一部が水面上に姿を現しましたが[ 6 ]、町の大部分は依然として水没しています。
