Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive.

They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

1939. "Texas whirlwind." View full size. Nitrate negative by David Myers.
I grew up in Oklahoma where these were common. We call them Dirt Devils.
[Like the vacuum cleaner? I've seen them called dust devils. - Dave]
It was great fun to try to get into the middle of one of these when I was a kid in the Texas panhandle. We learned quickly to keep our mouths shut if we didn't want to eat dirt.
That tells me so much about Texas . . . and the phenomenon of weather. What a great picture!
