For some quadrangles, supplementary augmented citations are denoted by a • (bullet). These augmentations are based on surficial geology, general geology, mineral resources, progress reports, special bulletins, water resources, and economic reports. Some quadrangles have multiple citations because they overlap into different counties. More information on these series of publications can be obtained at our publications web page.
