1:100,000 Topographic Maps
The 1:100,000 scale US Geological Survey (USGS) topographic maps provide a detailed representation of the Earth’s surface, capturing both natural and man-made features. These maps are designed to offer a comprehensive view of large areas, making them ideal for a variety of uses, including environmental studies, land use planning, and outdoor recreation. The scale of 1:100,000 means that one unit on the map represents 100,000 units on the ground, allowing for a balance between detail and coverage. Key features of these maps include contour lines to depict elevation changes, water bodies, vegetation, roads, and urban areas, providing a thorough overview of the terrain.
The Bureau of Land Management (BLM) Surface Management Status Maps, also at a 1:100,000 scale, are based on the USGS topographic maps but include additional information about land ownership and management. These maps are particularly useful for identifying which federal agency manages specific parcels of land, such as the BLM, Forest Service, or National Park Service. This information is crucial for land use planning, resource management, and recreational activities. In addition to the topographic details found on USGS maps, BLM maps feature color-coded land status layers, facilities, campgrounds, trails, and recreation areas, making them a valuable tool for both land managers and the public.
Both types of maps share several common features, including detailed topographic information, geographic coordinates, and elevation contours. However, the BLM Surface Management Status Maps provide additional layers of information related to land management and jurisdiction. The 1:100,000 scale is particularly useful for providing a broad overview of large areas while still offering enough detail for practical field use. These maps can be used for activities such as hiking, hunting, land management planning, and environmental assessments, offering a versatile and comprehensive tool for understanding and navigating public lands
