I am not expert about Grand Canyon, but based on Wikipedia it's not made by glaciers. It is also a bit too south for that. Also, usually glaciers smooth landscape.

Climate changes... Plain and simple. So all would agree on that.
Antarctic 'Grand Canyon' Carved by Glaciers

"Later the canyon was blocked three different times by glaciers. Each time these glaciers formed lakes, which filled with sand and gravel. Floods from the melting glaciers at the end of each glacial period recarved the canyon, deepened it, and removed most of the sand and gravel."

More examples, Greenland isn't named that because it's covered in ice and Iceland isn't named that because it isn't.
