J No. 5 Pulgas Base California

A detailed map showing the Pulgas Baseline east of San Francisco near the San Antonio Creek. The maps shows the Embarcadero, Jone's, Steinbergen's and Carr's properties/farms. Shows some topographical features, roads, buildings and vegetation. Includes an elevation profile of the Baseline. IMPORTANT NOTE: All of our United States Coast Survey (USCS), United States Coast & Geodetic Survey (USC&GS), and similar maps and charts have been professionally unfolded and flattened using humidity baths, semi-permeable membrane, and drying blotter techniques. Most others you typically see on eBay have not been, and worse, are quickly and crudely unfolded for the low-quality photos you see. Unfolding these maps in that way is damaging and weakens them. Please be aware.
