50,000 years ago a bit of wayward rock about 50m across met Earth and left this 1200m wide crater in Arizona.
Ponder the momentum of 50m bit of rock that left a hole over a kilometer wide and 200m deep.
If one was coming. Would we know?

UPDATE: JoeV in comments adds an interesting link to Tracking space junk at Satview.org. An old satellite is coming in right now. It’s over Alaska (moving fast) at 153km high and falling quickly. Cosmos 1220, a Soviet era military surveillance satellite. Eddie adds a different link which suggests Cosmos is expected to crash into the Pacific in hours. Amazing what you can find out on the Internet.
For all those other thoughts…
Interference patterns ripple through clouds at my favourite rock pool.

I took this flying from Denpasar to Perth. Glorious ancient landscape in the dry season north-west WA. Click for a larger broader image.
UPDATE: thanks to help from Steve R W, I think I’ve found the location. It appears to be part of a long ridge in The Barlee Range, just north of the Frederick River in the Pilbara area of Western Australia. It is so remote, Google Earth tells me “you can’t get here from where you are”.

A couple of hours north of Perth. It’s not snow.
Funny what you see driving home from the shops…. hundreds of thousands of tons of water-vapor had condensed in giant suspended formations. No one seemed to notice.

For all those other ideas…
We could discuss that 95%-certain sermon from yon IPCC…
Our taxpayers give us this day our daily bread,
and forgive us our debts,
as we also have forgiven our debt to our largely free university education,
and lead us not into skeptic temptation but deliver us from evil.

Yes, this is the unthreaded thread this weekend…
There is so much to talk about…
