Setting:
Located in the NW4 Sec. 23 T9S R2W SBM, at a point around 400 feet northwest of the center of the section survey, approximately 1.5 miles northeast of Pala. The mine workings are within the center portion of the southern half of the Douglass dike, which extends for about 4000 feet along the base of the southeastern side of Tourmaline Queen Mountain, and was developed in the early 1900's.
History:
In 1914, Frederick Merrill reported that the American Lithia and Chemical Company owned a half interest in the Douglass claim, with the remaining interest held by T. A. Blakeley, of San Bernardino.
In 1951, Richard H. Jahns listed the principal output as gem and specimen quality tourmaline and quartz. The mine was considered abandoned by 1958. In 1963, F. H. Weber noted that in addition to the usual pegmatite minerals, honey-yellow to orange-brown crystals of grossularite, and iridescent stains of marcasite occur in the dike.
The land is now managed for the benefit of the Pala Band of Mission Indians by the Bureau of Indian Affairs (BIA).
