The Hoosier Gulch was a mining district, also known as the Hoosier Pass district,[3] located along the Park-Summit County line, at the headwaters of the Blue River, ten miles south of Breckenridge, at over 10,000 feet in elevation.[4][2]

Mining operations
editThe mining district contained the Bemrose-Bostwick placer camp, founded by William Bemrose and Henry M. Bostwick,[5] which primarily produced from 1871 to 1877 and between 1914 and 1941.[6][2] The Bemrose-Bostwick placers were worked intermittently as there was not sufficient water,[3][7] but had produced $25,000 worth of gold by 1879.[1][2] The district also contained other gold placer camps that were being worked by around 1860, and there were some operations as late as 1959.[3][2]
Discovery
editThe gulch was discovered by men from Indiana, "The Hoosier State," in 1860, providing its name, and it in turn provided the name of Hoosier Pass, located nearby.[8]

Commencing in the extreme southern part of the mining-districts of the county, and on the head of the Blue River, the first mining-camp is that of Bemrose & Co., in Hoosier gulch, a tributary of the Blue River. This company is working in an old side-channel in good pay-grael, overlaid with cement. Four men are employed during an average season of only two and one-half months, caused by the early failure of water at the location worked, which is over 10,000 feet above sea-level. The ground pays about $12 per day to the hand employed.

According to Henderson (1926), the Hoosier Gulch District overlaps the Pollock District. Lying along the Park-Summit County line, the district consists of historic placer operations at the headwaters of the Blue River (Dunn, 2003). It bounds the Upper Blue River District to the north. It is interpreted to include the mines discussed in the paper by Singewald (1951). Parker (1974) describes the Bemrose and Bostwick Placers as producing from 1871 to 1877 and again sporadically from 1914 to 1922. Singewald (1951) describes the Bemrose Mine, in addition to the productive placer, as consisting of a shaft into mineralized rock consisting of replacement deposits in Pennsylvanian rocks. The mines of Monte Cristo Gulch are also included in the Hoosier Gulch District. The Monte Cristo Mine also produced a small amount of gold and silver from a lode deposit possibly in Dyer Dolomite.

I. F. Lincoln, one of the lessees of the Bemrose-Bostwick placer in Hoosier gulch, states that the actual washing of the gravel of the high bars of that rich gulch was commenced this week. He expects that a good clean-up for the season will be made, as there is a better supply of water for hydraulic mining this year than for several years.
