1986 Map of Bartine Ranch NW

About this map

The Old Pony Express Trail cuts a diagonal path across the landscape of Kobeh Valley, providing a clear record of this important mid-19th-century mail route. Surveyed by the Geological Survey in the 1980s, the map reveals a remote Nevada basin defined by seasonal drainages and essential water sources. Water is the primary driver of human presence in this arid region, evidenced by landmarks like Mint Well and the braided courses of Colls Creek and Rutabago Creek as they flow toward Willow Wash. The map documents a sparsely populated area where historical transit routes like the Pony Express were dictated by the natural contours and hydrology of the high desert floor.
