Road trip in Alberta - Big Rock
Peggy and Ted are taking me on a road trip today and I will be posting random photos along the way.
“Big Rock (also known as either Okotoks Erratic or, by the Blackfoot, as Okotok) is a 16,500-tonne (18,200-ton) boulder that lies on the otherwise flat, relatively featureless, surface of the Canadian Prairies in Alberta. It is part of the 930-kilometre-long (580 mi) Foothills Erratics Train of typically angular boulders of distinctive quartzite and pebbly quartzite.
This massive angular boulder, which is broken into two main pieces, measures about 41 by 18 metres (135 by 60 feet) and is 9 m (30 ft) high. It consists of thick-bedded, micaceous, feldspathic quartzite that is light grey, pink, to purplish. Besides having been extensively fractured by frost action, it is unweathered. “
