Since rock walls do not contain any cementing material, the runoff water is retained, filtered, and slowly released through the existing crevasses.
Transported logs and wood fragments occur in siltstone and sandstone units variously interpreted as river channel deposits, flood deposits and crevasse splay deposits.
In clear weather they got across the final crevasses and moved down just ahead of a descending cloud base.
They found that a crevasse 15 km in height in an ice shell 75 km thick would trap y4.9r109 m3 of ammonia- water.
Each time you move from one gallery to another you cross the line of a crevasse and glimpse the horizon.
These sheer crevasses provide a strongly contained view of the horizon.
Sheeted sandstone deposits represent crevasse splays, which deposited sand more uniformly in overbank areas.
They are assigned to a crevasse splay origin.
