in Geology Welcome to Travels in Geology, a special online section of Geotimes! Each
month, we will review geologically significant places to visit museums,
fossil dig sites, caves, mountain ranges and more.
We're always open to suggestions of places to review. Please
send your ideas to email@example.com.
In the 20th century, granite outcrops became an important medium for honoring
people in U.S. history. Visit Stone Mountain in Georgia and Mount Rushmore and
Crazy Horse in the Black Hills of South Dakota.
