Castle Valley: A Salt Valley
• How do salt valleys form?
• Salt layers laid down in the Pennsylvanian, then buried
• Weight of rock causes salt layers to flow (slowly)
• Flows meet rock ridges, pile up and flow upward, forming salt domes (up to 4500 m thick)
• Much later, in the Tertiary, gradual regional uplift caused Colorado River to start cutting its channel. It reached the salt layers, dissolved the top ones, and the caprock settled downward.
• Further erosion by the Colorado River will likely cause valleys (all eight) to settle further in the future
Full Transect• From southwest to northeast, crossing both Moab
and Castle Valleys
• Burkholder is an oil well

• Formation my house is built on:
• Qaf: Alluvial-fan deposits
• Poorly sorted, angular to subrounded gravel, containing cobbles and sparse boulders, in crudely bedded to unstratified granules, sand, silt, and clay matrix; cut-and-fill channel features locally present; deposited at the foot of mountains, cliffs, and at the mouths of streams; thickness commonly less than 15 meters (50 ft); Holocene to late Pleistocene.
