Breaking news as wildfire burns...

just one mile west of my residence in the Scabland pines, near Cheney, Washington. Local police knocked on my door around 1:30 pm PDT and ordered my evacuation, so I grabbed my camera gear and chased the story.

Tinder dry conditions in the rangelands and ponderosa pine forests in rural eastern Washington are easily ignited mid-summer, but the cause of this fire remains unknown at this time.

RE-POST: Mars 2020 mission is ready to launch...

atop an Atlas V-541 rocket from Cape Canaveral, carrying the next-generation scientific rover, named Perseverance, this Thursday, 30 July 2020 at 7:50 am EDT. Link to more information about this extraordinary machine: Mars 2020 Perseverance Rover. Landing on the red planet will occur in late February 2021.

What fascinates me, though, is that this robotic geologist will land on/near an ancient deltaic system that enters the crater from the west. I have lectured about this landform and depositional system in various courses from physical geology, fluvial geomorphology, sedimentology and stratigraphy, and more.

Fish Lake is my aquatic office...

and my paddleboard is my desk this summer in eastern Washington. The tyrant governor can’t make me wear a mask out here!

Bright comet C/2020 F3 NEOWISE...

is now a spectacular naked-eye object. Get up at least an hour before sunrise and cast your gaze toward the north-northeast, low above the horizon, to spy this fleeting visitor to the inner solar system. You can’t miss it.

UPDATE: This comet is now an easy evening object to see toward the north-northwest, a little more than an hour after sunset: How to See Comet NEOWISE in the Night Sky This Month. Super in binoculars! Get out and take a look… you can sleep when you’re dead.
