Wilkerson reported in short form that the information in this paper is taken largely from published and public sources. Wilkerson discrepancies in mine or geologic descriptions. I have changed verb tenses for readability and have used some paraphrase. Wilkerson has expanded abbreviations or special characters with full text (e.g. feet instead of ft., inches instead of “) Italics indicate quotations. Authors of the original information are indicated at the end of each paragraph. Paragraphs without a citation are our own materials. The maps in this report have been compiled and rectified from digital and paper copies of original sources that were made at different scales and in different geographic projections. Therefore, many of the maps had to be adjusted or stretched.
They do not fit perfectly. Most are accurate to within 100 feet, but reproduction and projection errors can be as much as 300 feet for some maps. PLSS means Public Land Survey System. That survey data was obtained from the U.S. Bureau of Land Management website:
MRDS, 2011, Mineral Resources Data System, U.S. Geological Survey, https://mrdata.usgs.gov/mrds/
This database relies on records that, in many cases, are inaccurate or imprecise. For example, if a report describes a mine as being in “Section 9”, with no other information, MRDS plots the mine location in the center of the section. If a mine is reported in “SW ¼” of a section, MRDS plots the mine in the center of that SW quarter-section.
Where Wilkerson could confidently adjust an MRDS location of a mineral deposit to features identifiable in aerial photographs or topographic maps, I did so.
Help me make this report better. If you have any photographs, memories or reports for this mine that you can share, please send them to yosoygeologo@gmail.com so that I can evaluate and incorporate that information and material into this paper.
LOCATION:
The Cinder Cone Lava Beds District is northeast of the Old Dad Mountains, west of Teutonia Peak, north of the Kelso Mountains, southwest of Shadow Valley, west of the Ivanpah Mountains and south of Solomon’s Knob in T.13 to 15N, R.10 to 13E, SBM. The district is in the East Mojave Scenic Area which is managed by the U.S. National Park Service. This district includes much, but not all of the Cima Volcanic Field. Cima Dome is three miles east of the District boundary. See report (here).
Deposit locations described by legal subdivision and latitude/longitude are provided in Tables 01 and 02. A commodity map for the district is provided in Figure 1 on page 12.
