Cobblestone Natural Bridge 
Rob calls this natural bridge Cobblestone because it is eroded into a conglomerate formation composed of rounded river rocks deposited there eons ago. It is located in Grand Canyon N.P. above the Colorado River on the unofficial trail between Deer Creek Falls and Fishtail Rapids (USGS Fishtail Mesa, Arizona Quadrangle). Go down stream from Deer Creek Falls for about a mile. From a broad beach, look carefully for cairns leading up a narrow canyon tothe north. This trail goes above the Tapeats sandstone layer of cliffs and is well-marked once on the route. Continue west through the Siesta Springs area. Above the trail, at an elevation of approximately 200 to 300 feet above the River, look for the Natural Bridge above a small side drainage. This hike, via Thunder River and Tapeats Creek, was about a five day round trip for Rob and hiking companions. Do not attempt this hike, or any hike into the Grand Canyon, without thoroughly researching the route and conferring with Park Rangers. |
