Diamond Creek is a small tributary of the Grand Canyon that flows year-round, joining the Colorado river 16 miles north of the dusty Hualapai Indian tribal town of Peach Springs, which is situated at the head of the southern end of
Peach Springs Canyon. This is one of the larger of the many hundreds of branches of the main canyon - it deepens gradually but steadily from an elevation of 4,950 feet at the town to 1,550 feet at the river. Vehicular access is possible along a bumpy, unpaved track (Indian Reservation Route 6) which thus provides the only such route to the Colorado between
Pearce Ferry and
Lees Ferry, 200 miles apart.
The track ends at a beach, with sand dunes and pleasant grassy areas where Diamond Creek meets the Colorado, and is quite a wonderful place. There are various sites for camping, in such a remote location that other visitors are unlikely. This part of the Grand Canyon is known as the
Lower Granite Gorge, and has weathered, colorful, igneous cliffs that rise steeply from the river; these are the oldest rocks in the canyon - underneath all the many different sedimentary layers, they date from the pre-Cambrian era, over 700 million years ago.
