A writer has contacted me looking for a geologist's insight into various Bay area rock climbing sites. Not my expertise area but maybe yours? DM me.

Iron sign next to Court Park, Memphis, says "Thomas Alva Edison / In 1865-66 Edison was military telegraph operator with the Federal occupation army, working in a building formerly at the east corner of North Court and November 6 Streets, and boarding next door.

As a result, he was discharged by a jealous superior, and he left Memphis."

Eerste goede foto van de meteoriet van gisteren:
First good picture of yesterday's meteorite (found in Koblenz):

It's a weird day. Today marks the one-year anniversary of my illegal firing from NOAA. And what a year it has been.
