Closeup of Pliocene lignite coal from a Balkan endemic nephropathy (BEN) village in Serbia. Lignite is low rank, or relatively unaltered (soft, or "brown") coal, and is characterized by a brownish color and appearance that often resembles wood. This lignite releases copious amounts of dissolved organic substances into groundwater.

Native Americans of the Miwok tribe in the northern Sierra Nevada, California carved these basins into the granite bedrock to produce salt for trade. They filled the basins with water from a salt spring and let the water evaporate, leaving a salt residue in the basin.

Tide pools provide habitat for a wide variety of Puget Sound flora and fauna.  During low tides, the captive inhabitants of tide pools may be closely inspected. 

Great Lakes water availability studies conducted by the U.S. Geological Survey aim to help characterize how much water the Basin has now, how water availability is changing, and how much water it can expect to have in the future.
