In this fourth installment of our Earth Science Week series, scientist Randy Orndorff gives us the lowdown on how geologic maps show what's down low, and he explains how these maps and the USGS's new geologic time scale and colors benefit planning, development, industry, and you.

Earth Science Week, Continued: Geologic Maps--The World Beneath Your Feet

Measuring Streamflow Through a Weir
Pew Creek below Johnson Road, Lawrenceville, Ga. The metal structure is a "V" weir. A sediment dam was built on either side of it to force the water through the weir. Scientists can calculate gallons per minute flow in the stream by timing how long the flow took to fill a bucket.

Cross Section of Sagittal Otolith
Cross section of a sagittal otolith from a juvenile Chinook salmon 79 days after emergence. The letters represent: H = hatch, E = emergence, FF = first feed, FW = freshwater residence, TDCK = tidal delta check, and D = tidal delta residence (40x objective).
