- Happy 6013th Birthday, Earth! According to the biblical calculations of Archbishop Ussher, the earth was created in the wee hours of October 23, 4004 BC.
- Via Emily Lakdawalla at the Planetary Society Blog, some excellent tee designs featuring planetary parks of the UN Department of the Exterior. Full-size here, for sale here.

- Chilean President Sebastian Pinera arrived in London, bearing rocks as gifts for British officials. Charlie Brown isn't the only one lucky enough to get rocks for Halloween, I guess. (tee below from here)
- Bill Watterson was (is) a great comic artist, but he really didn't (doesn't) know much about geology did he? Via GeoCastAway: Blooger fuzzes images when I resize (thanks, Blooger!), so click for clarity.

Thanks!)

I've noted this kind of discrepancy before: where I live, the Willamette River drains an area about 5% of the Colorado River's, yet its mean annual discharge is about 60% greater than the Colorado's. And the watersheds of the Colorado and Columbia Rivers are about the same size, yet the latter's mean annual discharge is about 13 times that of the former.
