Abstract
The Sphinx consists of more than 1000 m (3300 ft) of synorogenic boulder and cobble conglomerate derived from a Late Cretaceous Laramide uplift that was located in the area presently occupied by the Madison River valley. Deposition of the upper Sphinx was probably controlled by source lithology, as the influx of very coarse, resistant clasts from middle and lower Paleozoic carbonates overwhelmed the fan system's ability to organize its load of sediment by normal fan processes. -from Authors
