The name may refer to Big Rock, the largest glacial erratic in the Foothills Erratics Train, situated about 7 km (4.3 mi) west of the town.. Before European settlement, journeying First Nations used the rock as a marker to find the river crossing situated at Okotoks. Interstate Park comprises two adjacent state parks on the MinnesotaWisconsin border, both named Interstate State Park.They straddle the Dalles of the St. Croix River, a deep basalt gorge with glacial potholes and other rock formations. Large boulders known as glacial erratics are scattered across the area. The word glacier is a loanword from French and goes back, via Franco-Provenal, to the Vulgar Latin glacirium, derived from the Late Latin glacia, and ultimately Latin glacis, meaning "ice". Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression.Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in The name may refer to Big Rock, the largest glacial erratic in the Foothills Erratics Train, situated about 7 km (4.3 mi) west of the town.. Before European settlement, journeying First Nations used the rock as a marker to find the river crossing situated at Okotoks. The isotopic record is based on the ratio of two oxygen isotopes, oxygen-16 (16O) and oxygen-18 (18O), which is determined on calcium carbonate from shells of microfossils that accumulated year by year on the seafloor. This was the last glacial period, also known as the Ice Age. Cedar Swamp Wildlife Management Area: New Hartford, Torrington Litchfield 275 acres Charles E.

Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited.Erosion is distinct from weathering which involves no movement. The ratio depends on two factors, the temperature and the isotopic composition of the seawater from which the organism secreted its shell. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Bretz conducted research and published many papers during the 1920s describing the Channeled Scablands.

The town's name is derived from "ohkotok", the Blackfoot First Nation word for "rock". His theories of how they were formed required short but immense floods 500 cubic miles (2,100 km 3) for which Bretz had no explanation.His theories of apparent catastrophism met with vehement opposition from geologists of the day, who tried to explain Geology.
