New Map Poster Available-The Cheney-Palouse Tract of Washington’s Channeled Scablands

A new map poster is available titled The Cheney–Palouse Tract of Washington’s Channeled Scablands. Using elevation data, it highlights a remote portion of the Eastern Washington landscape shaped by catastrophic ice-age floods. During the last ice age, a lobe of the Cordilleran Ice Sheet formed an ice dam that blocked a major valley in what […]

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 […]

Happy National Geologic Map Day!

Recently, DGER recreated the “page-size” Geologic Map of Washington as a digital product (in GIS), enhancing the appearance of the cartography and improving its resolution. Educators often find this map useful for introducing basic Washington State geology to their students and appreciate that it can be printed on a standard home printer. Click on the […]

Edible Geology for Geologic Map Day

In celebration of Earth Science Week and National Geologic Map Day (which is tomorrow, 10-18), DGER geologist and baker extraordinaire Carrie Gillum has indulged us with some edible cartography today! She spent several days baking and preparing the decorations, which are 100% edible and use such materials as pretzel sticks and spaghetti noodles to represent […]

Seabeck-Poulsbo Geologic Map Now Available as 3D PDF

3D PDF files are a fun way to explore the relationships between topography, surface geology, and subsurface geology (represented by cross sections and borehole data). What’s even better is that no expensive or special software is needed to view them! Files can be viewed and manipulated with the freely-available Adobe® Reader®. Users can zoom, pan, […]

Geology Portal Gets Updated

Whether a newbie to DGER’s online geologic information portal or an old hat at using it, you’ll be interested to know that we have just released the latest version of it to the public! The latest version runs on Esri’s ArcGIS for Server 10.1 platform, but there won’t be a noticeable difference to the way […]
