[4] In southern New Mexico, the Crevasse Canyon Formation contains fossil soils (paleosols) typical of a humid climate (alfisol and inceptisols).

The underlying Mojado Formation contains paleosols typical of an arid climate (aridisols), suggesting a shift from an arid to a humid climate across the lower Cretaceous - upper Cretaceous boundary in this region.

[5] Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.

[7] Two dinosaur fossil trackways have been identified in the formation near Elephant Butte Reservoir.

[2][9] Tschudy (1976) identified the Crevasse Canyon formation as Coniacian and Santonian by palynology of coal and shale.
