Location and History
This district is in the general vicinity of and east of Baldwin Lake, which is in the northern part of the San Bernardino Mountains. Gold was reported to have been mined here by Mexicans possibly as early as 1800. The Rose mine was active in 1860, and there was considerable activity in the district in the 1890s and early 1900s. The Doble mine was active again in the 1930s and 1940s. The lake was named for C. G. Baldwin, first president of Pomona College.
Rocks in this district include mica schist, quartzite, limestone, and granite. The ore deposits consist of systems of irregular quartz-calcite veins containing free gold, scheelite, and sulfides. The greatest depth of development is about 400 feet. There are also placer deposits in the district.
