25th Amendment? We can’t even get network news to air it or even mention it. It’s a massive national media coverup to hide the fact the we have an addled president.

Nearing the end of our PNW field studies, we traversed a part of NV that doesn't look like people's conception of NV: the Ruby Mtns, which were proposed as a nat'l park, and should have been one. Alpine topography in Lamoille Canyon with exposures of a metamorphic core complex.

Day 14 of our PNW field studies found us driving home across northern Nevada. We stopped for the night at at Angel Creek and Lake in the Eastern Humboldt Range. This Range was considered for national park status in the 1990s. The rocks are part of an ancient metamorphic core complex.

Day 12 of our PNW field study was a near-total loss to the rain, but what a morning on Day 13! The Grand Teton Range is a fault scarp that rises abruptly a mile above Jackson Hole. The crustal rocks are among the oldest rocks in the western US, at 2.7 billion yrs. And there was the wolf pursuit!

Day 11 of our field studies of the Pacific Northwest and Northern Rockies. Despite the rain and almost snow, I wanted to explore the Upper Geyser Basin near Old Faithful, as I had few chances to do so over the years. The variety of geysers and hot springs is unique in the world. 1/2

Day 11 of our PNW field trip, the 7th day of summer, and we awoke...to snow. We left to see iconic Old Faithful. My students wouldn't have let me get away with anything less! They had 3 hours to explore in the freezing rain (or drink lattes and earn Jr Ranger Badges). 1/2

Day 10 of our field course in the PNW...Yellowstone NP on a weekend. Despite the rain and snow (!), we had to plan our stops carefully. We managed to find spots at the Norris Geyser Basin, the hottest, most acidic landscape in the park. We walked the Porcelain Basin. Fantastic!

On day 10 of our PNW journey, we awoke to cold, almost freezing rain. But we were in Yellowstone! On a weekend. Our stops were carefully calibrated to avoid the worst crowds. 1st stop was Yellowstone Falls and the Grand Canyon of the Yellowstone. This is a young feature, less than 1 million yrs old.

Day 9 of our PNW exploration (my day count is off!). A change of pace: not spectacular in the scenic sense, but rich in history. The Madison Buffalo Jump St Pk preserves a cliff where bison were stampeded to their deaths, providing the hunters with food and clothing and shelter.

Day 8 of our studies in the Pacific Northwest was a 400 mile long journey across Idaho and Montana with few stops. But one was spectacular: the Camas Prairie near Perma reveals gigantic ripple marks as high as 50 feet caused by the Missoula floods traveling at 80 mph

Some people special to me donated their lifelong collection of rock and fossils to the department. One item stood out... I've never held one and rarely seen one for sale. Can any of my geology friends identify it, and explain why it's important in our science?
Very lumpy looking sample of a dark mineral or rock about 3 inches across.

With all the disturbing things going on, I want to think of something more positive. Here are some (locally) rare birds I've seen this week; a Hudsonian Whimbrel, and a Hooded Oriole. Both arrived in the region a bit early.
