3 Fire-related Maps

• Wildfire Potential
• Probability of Large Fire
• Probability of Fire Spread

There are three fire-related triangles used to explain fire growth and expansion. The smallest scale "Fire Triangle" factors in oxygen, heat, and fuel. The "Fire Behavior Triangle" factors in topography, fuel, and weather. While the large-scale "Fire Regime Triangle" factors in ignition source, vegetation, and climate.

USGS water data expert Garret Welsh measures water flow in the pouring rain at the Straight River near Faribault, Minnesota. This measurement recorded the 6th highest flow in the station's 59-year history, highlighting the severity of current flood conditions. Such data is crucial for emergency managers and forecasters to protect communities at risk.

This is a 1:2,000,000-scale map of Arizona with the entire Arizona National Scenic Trail shown in red. The basemap is the USGS Topo basemap taken from USGS The National Map. 

A 7.5-Minute Topo or 1:24,000 scale map of the Arizona National Scenic Trail runs through the Gila River Canyons west of the town of Kelvin. This map shows shaded relief, contour lines, hydrography, land cover, place names, and roads. 

This is a close-up of a 1:100,000-scale topographic map (100K Topo) of the Arizona National Scenic Trail (AZ NST) from the Kaibab Plateau at top to the Grand Canyon North Rim at bottom. The AZ NST is highlighted in red. This map shows contour lines, hydrography, landform names, land cover, federal lands, roads, and structures.
