XKCD. Brilliant. Gotta love Randall.
Excellent graphic. One correction: “Oregon is scoured by huge floods…” should read “Present day Washington is scoured by huge floods…” Little to none of the Lake Missoula and Lake Columbia dam burst floods scoured Oregon; the coulees and scab lands are in Eastern Washington.
Oregon has been changed to Washington in the original at XKCD
Bravo! Should be as convincing (and becoming a classic) as a Tamino graph. Hmmmmm…
Spectacular graph! Nice to see it vertically presented.
Although the hockey player would need to be 12 feet tall.
Two corrections: Beringia was never covered with ice. The proto-americans lived there for several thousand years before the way was clear further east an south.
The great floods of the inland Pacific Northwest were primarily in eastern Washington. In Oregon the Boardman flats area was affected except for both Washington and Oregon in the Columbia gorge. In Oregon the flood waters spread out over the Willamette valley but also on the Washington side around Longview.
Reblogged this on EcoLabs.
And the text under the image at XKCD:
[After setting your car on fire] Listen, your car’s temperature has changed before.
Wow. A truly excellent visualization!
To add the hover text: “[After setting your car on fire] Listen, your car’s temperature has changed before.”
That long, slow cooling that has been going on for some 8,000 years is something much of the general population doesn’t know about.
So true. Don’t know how many times I’ve made that point in response to the “Of course we’re warming, we’re coming out of the Ice Ages” meme.
The glacial outburst flooding crossed Washington, not Oregon.
Fabulous! Just the best, thanks.
And why stop there:
I love the way he makes the graph long enough to see the uptick at the end. And how he keeps your interest through the long, slowly changing times by including snippets of history along the way.
