This sequence shows the deposited layers from youngest (top) to oldest (bottom). For clarity, the entire record of visible layers in this area is shown, including those not found in Canyonlands.

Geologic names are actively debated and vary regionally, so sometimes two names are listed.
Dominant layers in Canyonlands include Navajo Sandstone through the Paradox Formation.
