The Tsunami Evacuation Map from the Washington Division of Geology and Earth Resources provides a large amount of information about tsunami evacuation procedures for the state of Washington. Each of the shaded areas in the image above can be zoomed in on for more detailed information including:

The Washington State Coal Mine Map Collection from the Washington Division of Geology and Earth Resources allows users to find maps of coal mines (including abandoned coal mines) in the state of Washington. The interactive atlas provides shaded "map areas" that the user can click on to find maps of coal mines in each area.

The Pennsylvania Department of Environmental Protection provides a large amount of information on oil and gas wells in the state in an interactive map. The map includes detailed information on wells across the state, generally split into conventional (blue) and unconventional (red) wells, and including:

The Wyoming State Geological Survey makes a large amount of information on oil and gas in the state available in interactive map form. The map includes:

The U.S. Energy Information Administration provides an interactive map showing the major tight oil and shale gas plays in the lower 48 states.

Tight oil and shale gas are two of the main types of "unconventional" oil and gas resources, and played an important role in the early-21st-century resurgence in domestic production of oil (beginning around 2009) and natural gas (beginning around 2006).

The Kansas Geological Survey's High Plains Aquifer Interactive Atlas provides a large amount of information on the High Plains Aquifer underneath western and central Kansas, which provides 70-80% of the water used in Kansas. Features of this interactive map include:

The National Oceanic and Atmospheric Administration's nowCOAST web app provides real-time observations, forecasts, and warnings for a wide range of coastal and inland weather, water, air, and hazard issues. Available layers and services include:

The U.S. Geological Survey has produced a visualization that shows how much freshwater is used by each state for a variety of purposes. The visualization resizes the states according to how much freshwater they use.

The visualization shows freshwater withdrawals for thermoelectric power generation, public supply, irrigation, industrial use, or total withdrawals, with data available in 5-year intervals from 1950 to the present.

The Pennsylvania Department of Environmental Protection's Office of Active and Abandoned Mine Operations has collaborated with Pennsylvania State University to produce the Pennsylvania Mine Map Atlas. This enormous resource contains thousands of detailed coal mine maps that can be overlaid on a variety of base maps for the entire state, including terrain, topographic and road maps, and aerial photographs.
