Timpanogos Cave National Monument is a United States National Monument protecting the Timpanogos Cave Historic District and a cave system on Mount Timpanogos in the Wasatch Mountains in American Fork Canyon near American Fork, Utah, in the United States. The site is managed by the National Park Service. The 1.5-mile (2.4 km) trail to the cave is steep, gaining close to 1,000 feet (300 m), but paved and fairly wide, so the caves are accessible to most. The three caves of the system, one of which is specifically called Timpanogos Cave, are only viewable on guided tours when the monument is open, usually from May through September depending on snow conditions and funding. There is the standard tour going through the cave system, and an Introduction to Caving tour which teaches Leave No Trace caving and goes further into Hansen Cave.
The three caves of the Monument that are tourable are: Hansen Cave, Middle Cave, and Timpanogos Cave. The three caves are connected by manmade tunnels blasted in the 1930s by the Works Progress Administration . The average temperature in the caves is 46 degrees Fahrenheit. Many colorful cave features or speleothems can be seen. Among the most interesting are the helictites, which are hollowed, twisted, spiraling straws of deposited calcite or aragonite. They are formed when water travels through the tube and then evaporates, leaving a trace mineral deposit at the end. Other speleothems found in the cave include: cave bacon, cave columns, flowstone, cave popcorn, cave drapery, stalactites and stalagmites.
Discovery of the caves
Martin Hansen discovered what became known as Hansen Cave in October 1887, reportedly while cutting timber he tracked cougar footprints high up the side of American Fork Canyon. Unfortunately, many of the features and formations in this chamber were damaged or removed by the Duke Onyx Company and the general public before the cave was made a national monument.
In 1913, a second cave was discovered nearby. While in the area to explore Hansen Cave with their families, James W. Gough and Frank Johnson were climbing an adjacent slope when they discovered the entrance to what is now known as Timpanogos Cave. Several others later entered the cave and viewed many of the formations inside, including the Great Heart of Timpanogos. However, before long knowledge of the cave and its entrance was lost. Some sources indicate that the entrance was lost due to a landslide in the area, while others say it was, in part, caused by the extreme secrecy of the original finders. Several years later, after hearing rumors of another cave, Vearl J Manwill came with a group of associates (which later became the Payson Alpine Club) in search of the mysterious hidden cave. On 14 February 1921 he rediscovered it (although many sources credit him as having discovered the cave). He immediately shared the information with the other members of the group. Having in mind the extreme damage that had resulted in Hansen Cave, that very night, the group dedicated themselves to the preservation of the cave. Of that night, Manwill wrote in his journal that they discussed ways "to preserve its beauty for posterity instead of allowing it to be vandalized as Hansen's Cave had been." Shortly thereafter they reported their find to the US Forest Service.
Later that fall, on 15 October 1921, George Heber Hansen and Wayne E. Hansen, Martin Hansen's son and grandson, were hunting on the other side of the canyon. While using binoculars to try to find deer, they came across another hole in the mountain, in between the other two caves. In a few days they came back, with 74-year-old Martin Hansen. Martin was the first to enter the cave, now called Middle Cave.
Current tours of the cave system enter the caves though a manmade entrance very close to the entrance discovered by Martin Hansen. Passing through a manmade tunnel, tours continue on to Middle Cave, before passing though another manmade tunnel to Timpanogos Cave. Finally, tours return to the surface through a manmade exit near the original entrance.
The cave system is located in the Deseret Limestone Mississippian age limestone formed around 340 million years ago. Notably the cave cavity was formed initially by a series of faults running off of the Wasatch fault. Since that time hydrothermal water action perhaps similar to that of Cave of the Winds in Colorado ,and uplift of the Wasatch Mountains has formed the modern cave system. With the speleothems first starting to grow within the last 750,000 years based on paleomagnetism of iron desposits within the formations as the cave system has been slowly lifted above the American Fork River.
