George Heber Hansen and Wayne Hansen
On October 15, 1921 Middle Cave was discovered by Heber (son of Martin Hansen) and Wayne Hansen (eighteen-year-old nephew of Heber Hansen). The Hansens started their day in American Fork Canyon hunting amongst the canyon ledges across from the caves. At lunch Wayne peered through field glasses and noticed what appeared to be another entrance between the two known cave entrances.
Did You Know?
Timpanogos Cave is known for its high concentration of helictites - a spiraling cave formation that seems to defy gravity. Helictites are formed when calcite crystals and dissolved impurities are forced out of a tiny central canal in the helictite by hydrostatic pressure.
