Nature and Science

Brown Trout

 

Three fish species are found in the American Fork River. In Timpanogos Cave National Monument, 2 species, brown trout and rainbow trout, are stocked by the Utah Division of Wildlife Resources. Only one species, the Bonneville cutthroat trout, is native to the area. Being pushed out by the more competitive exotic fish, Bonneville cutthroat trout only exists in the extreme upstream sections of the American Fork River.

frost cave formation

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 calcium carbonate. The delicate nature of these tiny crystals makes them particularly susceptible to damage and vandalism.
