Tonto Natural Bridge State Park:

Tonto Natural Bridge - believed to be the largest natural travertine bridge in the world! Brief History:

   Tucked away in a tiny valley surrounded by a forest of pine trees, Tonto Natural Bridge has been in the making for thousands of years. It is believed to be the largest natural travertine bridge in the world. The bridge stands 183 feet high over a 400-foot long tunnel that measures 150 feet at its widest point. Tourism at the Tonto National Bridge State Park is up in 2014-2015 according to an article by The Payson Roundup - Bridge Rebounds - State Park visits top 100.000.

   The discovery of the small and beautiful valley between Pine and Payson was documented in 1877 by David Gowan, a prospector who stumbled across the bridge as he was chased by Apaches. Gowan hid for two nights and three days in one of several caves that dot the inside of the bridge. On the third day, he left the cave to explore the tunnel and green valley surrounding it. Gowan then claimed squatter's rights.

   In 1898 he persuaded his nephew, David Gowan Goodfellow, to bring his family over from Scotland and settle the land permanently. After a week of difficult travel from Flagstaff, the Goodfellows arrived at the edge of the mountain and lowered their possessions down the 500 foot slopes into the valley by ropes and burros.

   Today, visitors can stand on top of the Tonto Natural Bridge or hike down below to capture the true size and beauty of this geologic wonder. The local newspaper, The Payson Roundup newspaper, just posted a news story about a new sign for the Tonto Natural Bridge. From the article, "Friends of Tonto Natural Bridge State Park and others gathered Saturday to celebrate the unveiling of a new sign intended to draw more visitors to the world’s largest travertine arch."

 

Geology of the Bridge:   

   According to state geologists, the formation of Tonto Natural Bridge went through several stages of development. The west side of Pine Creek was formed by a flow of lava in the form of rhyolite. The rock eroded, leaving behind purple quartz sandstone. The rock layers were then lithified, tilted, and faulted.

Volcanic eruptions covered the rock layers with lava, forming a basalt cap. Through erosion, the basalt cap broke down and was shifted by faults, creating Pine Creek Canyon.

   Precipitation began seeping underground through fractures and weak points in the rock, resulting in limestone aquifers. Springs emerged as a result of these aquifers, carrying the dissolved limestone and depositing calcium carbonate to form a travertine dam. The waters of Pine Creek then eroded through the travertine and formed the Natural Bridge.
