Wayne Morse Free Speech Spot


From The Register-Guard, Eugene, OR
Commissioners approve rules on plaza hours

"As part of the rule change, the county is now calling the area the Wayne Morse Terrace instead of its more commonly used name, the Wayne Morse Free Speech Plaza. A smaller area within the concrete plaza is now the designated free speech area."

Mars, Waypoint 1 breccia (Darwin)

Curiosity's view from Waypoint 1, across the basin of Gale Crater. Foothills of Mount Sharp at top, a smaller crater in the middle, and a larger crater partly covered by sand drifts (bluish) extending across the frame:

Darwin is a rock outcrop at Waypoint 1 that's getting a close look for clues relevant to the geologic and hydrologic history of Gale Crater. Below is a series of images, from very close-up, to wide angle. Apparently it is a breccia, or possibly a conglomerate:
