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.
