In foreground, red-weathering rocks are Hue Shale (oil-prone source rock with is present throughout 1002 Area) and dark gray rocks are Kemik Sandstone (lateral equivalent to Thomson sandstone, main reservoir in Pt. Thomson field).

Lung from a captive, adult male, 930-g Gyrfalcon, found dead in Washington, USA.  Lung shows diffuse severe congestion and edema.  

The falcon became ill and died after consumption of a (presumptively) HPAI virus-infected American wigeon (Anas americanus) from Wiser Lake in Washington, USA. Waterfowl carrying HPAI viruses were detected at Wiser Lake in

Earthquakes at Mount Rainier from 2010 to 2019. As shown in the graphic, fluids from the magmatic system beneath the volcano rise through existing cracks and weaknesses in the crust. Along with rainwater and ice/snow melt, these fluids combine to create a hydrothermal system within the volcano. When pressurized fluids move along faults in the shallow subsurface, they

Zizia - Every garden deserves a set of plant folks from the carrot family. This is Golden Alexanders, it even comes with a bee that only uses its pollen to feed its young, Andrena ziziae. Flat-topped and little flowers, this creates the perfect feeding platform for little wasps and bees. Check out the rest of the family and include them in your gardens too. Photo and

Zanysson - A crabronid wasp. Most of the stinging wasps are fairly badass in aspect, to use a technical term. This one certainly is worthy of a tattoo on someone's chest and was collected by Merle Shepherd from Spring Island along the coast of South Carolina. It is unclear which species this is, but perhaps someone will reveal that to us. The group as a whole are

Yucca filamentosa. A wild eastern Yucca. I always thought the odd Yucca in some beatup corner of the East was an escapee. But this is not the case as you can see here. Pollinated by moths, not bees.
