New and improved! Have another look at DNR’s landslide hazard website

There have been some important changes to our landslide hazard website since we last blogged about it on November 1, 2012. We have improved the resolution of the map by adding the National Weather Service (NWS) forecast zones. A shaded relief of elevation, along with the addition of salt and fresh water features, improves the […]

Watching Washington Evolve

Our talented cartographers have put together a great animation showing the evolution of Washington geology. Based on the previous work of Jack Powell and John Figge, the cartoon shows the accretion of terranes through geologic time from the Neoproterozoic (~750 million years ago) to the present. It demonstrates how the breakup and reconstitution of ancient […]

New Geology Display in NRB Rotunda

The introduction of the mandate that the DGER office door must now remain closed during business hours (due to security concerns) meant that the public could no longer view our rock and mineral collection on a walk-in basis. No matter–this inconvenience motivated us to keep geology in the public eye by creating an updated display […]
