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.

Even though temperatures can be below freezing in the winter at Timpanogos Cave, the caves keep a fairly constant temperature of 46 degrees F and 100% humidity. In years of heavy snowfall, snow is shoveled off the cave trail in preparation for opening the caves and cave trail in the spring.
