{"product_id":"map-of-donnelly-idaho-by-usgs-1985-cascade-reservoir-long-valley-lake-fork","title":"Map of Donnelly, Idaho by USGS, 1985 – Cascade Reservoir, Long Valley \u0026 Lake Fork","description":"\u003cp\u003eTitled “Donnelly Quadrangle,” this US Geological Survey topographic map records the Donnelly, Idaho area as surveyed in 1985 and published with a 1986 imprint. Marked “provisional,” it belongs to a class of USGS maps issued to make current geographic information available even as cartographic refinements continued. At 1:24,000 scale, it presents the landscape with the precision and intimacy characteristic of the 7.5-minute quadrangle series: roads, trails, watercourses, terrain, settlement patterns, and vegetation zones are all rendered in a disciplined visual language. The result is both scientific document and historical portrait, preserving the mid-1980s geography of a mountain valley community poised between rural settlement, recreation, forestry, and the broader transformations of central Idaho.\u003c\/p\u003e\n\u003cp\u003eDonnelly appears within Valley County’s Long Valley, a broad intermontane basin framed by the rugged uplands of west-central Idaho. The map’s contour lines articulate the subtle rises, benches, and slopes surrounding the town, revealing a terrain shaped by water, glaciation, and the long processes of mountain erosion. The mapping is especially valuable for the way it clarifies the relationship between settlement and landform: Donnelly lies amid open valley country, with roads and local routes threading between agricultural parcels, timbered areas, and water features. Green tints indicate vegetation, while blue highlights the reservoirs, lakes, streams, and wetlands that define the local environment. This careful color language makes the quadrangle immediately legible while retaining the density expected of serious topographic cartography.\u003c\/p\u003e\n\u003cp\u003eOne of the dominant geographic features is Cascade Reservoir, the large impounded body of water south and west of Donnelly that has shaped local recreation, irrigation, habitat, and transportation patterns. Its blue expanse anchors the composition and contrasts vividly with the greens and browns of surrounding land. Nearby Lake Fork and other streams trace the drainage network feeding the valley, their courses revealing the hydrological logic of the region. For anyone interested in Idaho’s mountain basins, the map offers a richly detailed look at how water organizes settlement and movement: roads skirt shorelines, trails follow natural corridors, and lowlands give way to wooded slopes. The unnamed ponds, marshes, and minor channels shown here add texture to a landscape often summarized only by its largest landmarks.\u003c\/p\u003e\n\u003cp\u003eThe US Geological Survey brought more than a century of institutional mapping expertise to works such as this. Founded in 1879, the USGS became the nation’s authoritative source for topographic mapping, creating a standardized visual system that could serve engineers, planners, scientists, land managers, and the public alike. Its quadrangle maps are admired for their balance of practicality and elegance: every contour, symbol, and color has a functional purpose, yet the whole composition possesses a quiet graphic beauty. In the Donnelly sheet, generalized color patterns combine with fine contour work to depict elevation, vegetation, and infrastructure without clutter. The “provisional” designation adds a further note of historical interest, suggesting a moment of active updating within the evolving national map archive.\u003c\/p\u003e\n\u003cp\u003eAs a record of Donnelly and its surroundings in the mid-1980s, this map invites comparison with the present landscape. It captures roads and trails before subsequent development, shows the pattern of habitation around a small Idaho community, and documents the relationship between human use and the natural setting around Cascade Reservoir and Long Valley. For historians, it offers evidence of land use and transportation at a specific moment; for geographers, it preserves the measured form of hills, valleys, waterways, and shorelines; for those drawn to the American West, it evokes a high-country place where settlement remains closely tied to terrain. Elegant in its restraint and rich in information, the Donnelly Quadrangle is a compelling cartographic portrait of central Idaho.\u003c\/p\u003e\n\u003ch2\u003eCities, towns and places on this map\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDonnelly, Idaho\u003c\/li\u003e\n\u003cli\u003eCascade Reservoir\u003c\/li\u003e\n\u003cli\u003eLong Valley\u003c\/li\u003e\n\u003cli\u003eLake Fork\u003c\/li\u003e\n\u003cli\u003eValley County\u003c\/li\u003e\n\u003cli\u003eVarious unnamed bodies of water and geological features depicted by contour lines\u003c\/li\u003e\n\u003cli\u003eNearby roads and trails\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHistorical context \u0026amp; cartographic details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMap name: Donnelly Quadrangle\u003c\/li\u003e\n\u003cli\u003eProduced by the US Geological Survey (USGS)\u003c\/li\u003e\n\u003cli\u003eHistorical 1:24,000 topographical map of Donnelly, Idaho and the surrounding area\u003c\/li\u003e\n\u003cli\u003eDated 1985 and published with a 1986 imprint\u003c\/li\u003e\n\u003cli\u003eMarked as “provisional”\u003c\/li\u003e\n\u003cli\u003eShows the geography of Donnelly, Idaho in the mid-1980s\u003c\/li\u003e\n\u003cli\u003eUseful for comparing historical and contemporary land use, development, and natural landscape changes\u003c\/li\u003e\n\u003cli\u003eFeatures generalized color patterns to depict elevation and vegetation\u003c\/li\u003e\n\u003cli\u003eUses intricate contour lines to show topographical changes, including hills, valleys, and water bodies\u003c\/li\u003e\n\u003cli\u003eBlue tones highlight water bodies, contrasting with green shades representing vegetation areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eLooking for a particular place?\u003c\/strong\u003e Review the detailed images to confirm that the town, landmark or feature you have in mind appears on the map.
