Timpanogos Cave, among the most popular attractions in northern Utah, is closing early this season so a long-stalled overhaul of the National Park Service’s visitor-staging area can begin along State Route 92 in American Fork Canyon.
The national monument’s last day of operation is Labor Day — Sept. 3 — after which work starts on relocating its visitor center, which has occupied a “temporary” structure in a rockfall-prone area since 1991. The National Park Service installed the current modular structure after its 1960s-vintage visitors center burned down.
“The interest was to use it for two or three years until they found the money,” said monument Superintendent Jim Ireland.
