About this map

The Blue Wing Mountains dominate the southwestern corner of this Pershing County landscape, where the high desert terrain of the Great Basin is mapped in modern detail. This section of northern Nevada is defined by significant elevation changes, with the arid slopes of the range giving way to the broad alluvial expanses of Long Canyon. Water sources remain rare and critical in this environment, with Heineke Spring providing a named reference point for surveyors and travelers in the northwestern reaches of the quadrangle.

Industrial and transport corridors are represented by State Hwy 399, which cuts across the central-western desert floor, providing the primary access through these remote townships. The map documents the precise township and range boundaries, such as t30n r27e and t29n r27e, reflecting the enduring legal framework of the American West. This 2021 edition provides a contemporary record of these land divisions and the few named landmarks that persist in this sparsely populated region.
