Community of Rockglen, SK. Rockglen, SK is situated in the Wood Mountain Uplands. This area was not affected by the last glacial movement, our fossils are often not buried by tons of overburden. Over the years these hills have yielded trilobites from 425 million years ago and brontosaurus skeletons from 100 million years ago. The "Canam Highway" A trip along the CanAm Highway truly presents most of the faces of Saskatchewan, from the prairies of the south, through the parkland of central Saskatchewan, into the forests and lakes of the rugged Canadian Shield.
