For those of you in the northern hemisphere, I hope you are enjoying summer.
Felix's WOGE 497 took us to "The Big Rock" in Southern Alberta, Canada where a gigantic and seemingly misplaced quartzite mega-boulder (moved by glaciers during the last ice age) juts out of the prairie landscape.
Below is WOGE 498. As always, please post the latitude, longitude and some commentary on the geology/geomorphology/geography of the feature in the satellite photo. The winner has the privilege of hosting the next WOGE. A list of previous WOGE locations can be found here:
Good luck!

ReplyDelete"This scenic landscape of varied islands and labyrinth passages owes its origin to a projection of Canada's Precambrian shield extending from eastern Ontario across the St Lawrence, where it underlies the Adirondack Mountains in New York state. This old (over 900 million years), complex rock, composed largely of hard granites and gneisses, was scoured and sculpted by glacial erosion into a "knob and hollow" surface. In the altered landscape after continental glaciation, the Great Lakes system found a new drainage route east from Lake Ontario, forming the present St Lawrence River. The hollows flooded and the rocky knobs became islands." [http://www.thecanadianencyclopedia.ca/en/article/thousand-islands/]

ReplyDeleteWell done Felix. The Thousand Islands are part of a larger scale feature called the Frontenac Axis, which is the narrow strip of Precambrian rock that connects the Canadian shield to the Adirondack mountains to the southeast. Where this crosses the St. Lawrence river, The Thousand Islands appear.
