Guests will have the opportunity to meet the author and purchase a signed copy of his latest release, The Riches of Our Universe. Light refreshments will be provided.

About The Riches of Our Universe:

Filled with vibrant photographs, maps, and diagrams, this coffee-table book traces the story of the Homestake Gold Mine through the discovery of gold in the Black Hills, 125 years of mining, the mine’s closure in 2001, and the creation of an underground science facility in its place. The book was published earlier this year by the SDSTA and is available for purchase at the Visitor Center.
