The description on the back of the card:
The Blue Hole, Castalia, Ohio. Six miles west of Sandusky, Ohio, on Route 101. The depth of the Blue Hole is unknown. The visible depth is apparently 50 or 60 feet. It finds its source in an underground river and maintains a temperature of 48 degrees, winter and summer. It is not affected by floods or drought. The volume of water flowing from this marvelous spring is seven million gallons daily, sufficient to supply a city of 75,000 population.

Genuine Curteich-Chicago “C.T. Art-Colortone” postcard, a tradename under Curt Teich Co., Chicago, Illinois
Established in 1898, the Curt Teich Co. was best known for its wide range of advertising and postcards of North America. By the 1920s, it was producing so many postcards with borders that they became recognized as a type dubbed "White Border Cards," creating an "era." Later, Curt Teich's innovations in this printing technique directly led to the production of what we now call “linens” by the early 1930s.
