The NRCS broadcasts a marvelous interactive “soils” map service, Web Soil Survey. From their homepage, “Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey.” It is the single best online map service for examining and evaluating soils.

American Memory: Maps – AM hosts 11 discrete map collections, ranging broadly from military maps of America’s Civil War, to Maps & Cartographic Items, to National Parks, panoramic maps, and more. The repository contains a trove of hard-to-find historic maps. A search for “Arizona” yielded 44 maps, most from the National Parks collection; AM is rich in Grand Canyon historic maps.

The results yielded a classic 1885 panorama: The Bird's eye view of Phoenix, Maricopa County, Arizona, sketched by C. J. Dyer. (W. Byrnes litho. Schmidt, Label & Litho. Co.).

HabiMap. Arizona’s newest map service, Habimap, serves up volumes of geospatial data on Arizona’s public lands, its water resources, vegetation, and animals. Some chief themes include: AGFD game management units, Arizona wildlife linkages, biotic communities, hydrography and land ownership.

From AZGF’s HabiMap introduction, “HabiMap™ Arizona is intended to be used as an early planning tool for landscape-level analysis and should be used in concert with all available data and expertise to ensure project plans address wildlife and habitat conservation at all levels.”

Every Arizona teacher engaged in study of the environment and its indigenous inhabitants should become familiar with HabiMap.
