ⓘ Tapeats Sandstone

The Cambrian Tapeats Sandstone is the lower geologic unit, about 230 feet thick, at its maximum, of the 3-member Tonto Group.

The Tapeats Sandstone is the highly erosion-resistant unit laid upon the Vishnu Basement Rocks in the central, parts of east, and parts of west Grand Canyon, Arizona. The unit comprises the base horizontal unit of the platform around Granite Gorge Inner Gorge on the Colorado River, and because of its hardness, creates the Tonto Platform upon which the two slope-forming, highly erodible units, the Muav Limestone, and Bright Angel Shale lie.

The Tapeats Sandstone and the Tonto Platform follow the Colorado River, and surrounding tributary canyons, creeks, watercourses, or washes, in a dendritic fashion, much like the branches of a tree.

The Tapeats unit is the bottom member of the Tonto Group, a typical marine transgression series of sandstone-conglomerate-shale-limestone, all part of a paleo sea, initially adjacent to land, the source of the Tapeats rocks-conglomerates and sand; a regressing sequence has the reverse order. The Tapeats Sea at the early Devonian ceased to deposit more Muav Limestone, and a period of erosion ensued, a deposition unconformity.

The Tapeats Sandstone was laid upon the Vishnu Basement Rocks, after an unconformity of erosion, the Great Unconformity, of 1.000 million years 1.0 billion. Besides the erosion unconformity, the Unkar Group of the basement rocks are also at an angular unconformity, being an 8-member sequence tilted at 45 degrees.

The horizontal Tonto Platform has hiking trails that cross it from the South Rim to North Rim, Grand Canyon for instance. The extensive Tonto Trail lies on parts of the Tapeats Sandstone, and the platform on the south side of Granite Gorge.
