Smoke has definitely settled in. This was yesterday over the Brockway Mountains in Upper Michigan. ๐Ÿ˜’

Finally made the trip to Kelleys Island, Ohio to see the HUGE glacial grooves left by the mile thick ice that once covered this region of North America. Closer examination of the grooves, however, suggest water flowing under the ice may have also played a role.

Hanging Rock near Lagro, Indiana on the Wabash River is a great example of a rarely exposed Silurian-aged pinnacle reef. These reefs are an important source of petroleum in the Michigan Basin around the Gaylord, Michigan area of the Lower Peninsula.

I once did a teacher's workshop titled "Hollywood and geology: the good, the bad, and the just plain silly!" Was a huge success.

Lake Bonneville itself was fresh water, only becoming salty as it evaporated and became landlocked. The Great Salt Lake is the modern remnant of Bonneville.

That's Church Rock between Moab and Monticello, Utah. Quite the geologic and human history behind that place.

The Loggerhead Shrike, also known as the "butcher bird" because of its habit of skewering its kill on barbed wire or small twigs, as seen on Antelope Island, Utah. Right after this photo, it flew off.

The Western Meadowlark on Antelope Island, Utah. A little shy at first, he finally starting singing after a few minutes.

Was just at that same spot back in March for a project I'm working on. Concerning the impact/salt dome debate; years ago, my wife found shatter cones and "odd" breccia in the area of upheaval dome, pointing towards an impact formation.

Good to know. I'm not replacing my D850/lenses anytime soon though. ๐Ÿ˜‰

You don't realise just how big Alaska is until you start driving around the state, although you don't really care as it's just so damn beautiful!

Great photo, Kevin!
I see you're using the Z a lot more these days. How is it comparing photo quality/use wise to the dslr; better, about the same, etc.?

1. Dante's Peak, even though everything is sped up.
2. The Core; enough said.
3. The Day After Tomorrow, although Dante's Peak is probably 1a in that department.

Great question, Wendy! ๐Ÿ˜‰

The Bonneville Salt Flats just east of Wendover, NV. The remnants of Lake Bonneville, you can definitely see why it gets its name "flats"!! ๐Ÿ˜

Hells Half Acre west of Casper, Wyoming is composed of Eocene aged sediments of the Wind River Formation. The sediment was shed off the Casper Arch, one of the major uplifts of the Rockies.

Time to start sharing pics from recent geology trip. Antelope Island in the Great Salt Lake is a great place to see 1.7 Ga Farmington Canyon Complex migmatites.

On our way to Salt Lake, had to stop by Soda Springs, Idaho to see the (claimed) only captive geyser in the world. The geyser is controlled by valves to erupt every hour on the hour for approximately ten minutes.
