Resource Map: Phoenix and Nationwide

Cooling sites, water, food resources, public lands, open shelters, and evacuation routes. Curated data for the Phoenix metro and the routes to Payson and Flagstaff works offline once you've opened this page. Nationwide layers load live when you have a connection.

Verify before relying on anything here. Sites close, springs dry up, and data has gaps. In an emergency, call 911, dial 211, and follow official instructions.

Read this before you use natural water or plants

  • Water: many desert springs are seasonal, low-flow, or dry, and rivers below dams depend on releases. Treat all natural water. Boiling is best: a rolling boil for 1 minute, or 3 minutes above 6,500 ft. Filtering and then disinfecting is next best (CDC).
  • Foraging: the "public lands" points mark habitat where native edibles (mesquite, prickly pear, saguaro, palo verde, desert ironwood) commonly grow. They are not foraging spots. Collecting is restricted or prohibited in many parks, preserves, and national monuments. Arizona's native plant law protects saguaros and many other species, and taking protected plants from public land needs a permit (ARS 3-908). Toxic plants like datura and oleander grow here too. See Bushcraft: food.
  • Hunting & fishing: a state license is required and seasons apply. In Arizona, see AZGFD for hunt units and community fishing waters.
  • Know what you see: the Wildlife Field Guide covers venomous animals, toxic plants, and edible species along these routes, with the laws that apply.
  • Tribal lands (for example Salt River Pima-Maricopa, Fort McDowell Yavapai, Gila River, Tohono O'odham, Tonto Apache, and Yavapai-Apache) are sovereign. Hunting, fishing, gathering, and camping are off-limits without tribal permission and permits.

Offline & printable

  • Open this page once while online and the site saves the Phoenix-area map data for offline use (see Save for offline). Map tiles you've already viewed may also show offline.
  • We don't bulk-download map tiles: OpenStreetMap's tile policy forbids it. Instead, download our printable maps: Phoenix metro resources (PNG) · Routes to Payson & Flagstaff (PNG) · both as PDF.
  • Carry a paper Arizona road map too. Phones lose signal and battery.
  • Only online: FEMA open shelters, USGS public-lands shading, live nearby OpenStreetMap search outside Phoenix, and the base map for areas you haven't viewed.

Hunting & fishing: state fish and wildlife agencies (all 50 states)

Licenses, seasons, and regulations are set by each state. Tribal lands have their own rules. Links go to each agency's official site (checked Oct 10, 2026).
