Unit Name: Swift Current Creek Beds
Unit Type: Lithostratigraphic
Usage: Currently in use
Age Interval: Late Eocene (37.2 - 33.9 ma)
Originator: Russell, 1950, p. 52.
About 14 km (9 mi) east-southeast of Swift Current Saskatchewan, in Lsd. 15, Sec. 5, Twp. 15, Rge. 12W3M.
At the type locality about 16 m (53 ft) thick. Exposed locally southeast of Swift Current. Vertebrate fossils indicate an upper Eocene age for the unit. Christiansen (1959, p. 30) combined the Swift Current Creek Beds and Cypress Hills Formation into one unit.
Thickness(m): Typical 16.
Soft, fine-grained sandstone; hard, coarse sandstone and, in part conglomeratic gravel. The hard sandstone forming the top 4 m (13 ft) of the beds contains vertebrate fossils. The gravel consists mainly of cherts and quartzites brought by rivers from the western mountains.
Originally named Swift Current beds by Russell and Wickenden (1933, p. 54); name changed in 1950 because original name was preempted. Christiansen (1959, p. 30) used the name Swift Current Creek Formation
