On This Date: A Little Time Capsule
1953 — The first production Chevrolet Corvette is built. The first production Corvette was built in Flint, Michigan, and General Motors says only 300 were built that first year, virtually by hand. For Hastings readers, this is a fun Upper Midwest car-culture note for a summer day when every classic convertible suddenly sounds like a good idea. Source: General Motors Heritage.
1864 — Lincoln signs the Yosemite Valley Grant Act. President Abraham Lincoln signed legislation giving Yosemite Valley and the Mariposa Big Tree Grove to California for public use, recreation, and preservation. It became a landmark step in America’s public lands story — the kind of “save the beautiful places” idea that still feels easy to understand from any river town. Source: Library of Congress.
1908 — The Tunguska event lights up the Siberian sky. NASA says an asteroid plunged into Earth’s atmosphere and exploded over Siberia on June 30, 1908, flattening trees for miles in a remote region. It is now one of the best-known reminders that space weather can be a little more dramatic than a passing cloud. Source: NASA.
