... adjacent to structurally high areas in pre-salt rocks that apparently were in existence prior to and during salt deposition. The northeast margin of the salt basin was bordered by the front of the ancestral Uncompahgre uplift, and arkosic debris derived from the crystalline core of the uplift was shed...

...) being deposited on the northeast and east flanks of the basin. These highlands persisted through Permian time and similar clastic deposition (“Permian” Cutler Formation) continued, depositing a thick wedge of arkose near the Uncompahgre front, which thins to the southwest to 2,000 feet of continental...

Vertical displacement was greatest along the Uncompahgre front, which caused tilting of the basin and contemporaneous development of an asymmetrically thick sedimentary sequence with great thicknesses of salt and arkose.
