This data set annotates dome elevation contours for i08_GeologicStructures_SacramentoValley. i08_GeologicStructures_SacramentoValley denotes the major geologic structures of the Sacramento Valley as mapped in USGS Professional Paper 1359, \"Late Cenozoic Tectonism of the Sacramento Valley, California\" (Harwood and Helley,1987). This data set was created by scanning the original sheets from (Harwood and Helley, 1987), the sheets were georeferenced individually and the geologic information was digitized using AutoCAD 2006. The accuracy of the digitized lines was deemed to be within acceptable error tolerances, with the digitized lines accurately matching the original drafted lines. In general, the width of the contact lines on the paper copy, accounting for scale, ranged up to about 20 meters (66 feet). During the original digitization, minor topological mistakes (such as identical rock units on both sides of a lithologic contact or unclosed polygons) and omissions (such as unidentified lithologic units) were applied according to the best available knowledge. Comparisons were made between the original mylar and colorized field sheets (as available), in addition to the Geologic Map of the Battle Creek Fault Zone, Northern Sacramento Valley, California (USGS Map MF-1298, 1981), the Geologic Map of the Chico Monocline and Northeastern Part of the Sacramento Valley, California (USGS Miscellaneous Investigations Series Map I-1238, 1981), the Geologic Map of the Red Bluff 30' X 60' Quadrangle, California (USGS Geologic Investigation Series Map I-2542, 1995), and the Geologic Map of the Whitmore Quadrangle, California (Geologic Quadrangle Map GQ-993).<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "mapName": "i08_GeologicStructures_SacramentoValley", "description": "
