For several thousand years, the first people of the area were heavily influenced by the climate. The Paleo-Indian people (12,000 BC) hunted large animals, and likely stayed near the shores of Utah Lake in the cool climate. As the climate warmed, Archaic people (~10,000 BC-AD 1) maintained a lifestyle of hunting and gathering. Excavations in other caves in American Fork canyon show that hunters used some caves as a base camp for hunting in the canyon.

Frostwork, like it's name depicts, resembles hoarfrost growing outside on a foggy winter day. Most frostwork found in Timpanogos Cave is formed from aragonite, an unstable form of calcite. The delicate nature of these tiny crystals makes them particularly susceptible to damage and vandalism.
