There are also kimberlite pipes found in the Birch mountains and the Buffalo Head Hills.

There are more kimberlite pipes around than a person thinks. 55 pipes have been found so far. Also, Back n the 1950's a man called Opdahl was walking the Pembina river near Entwistle and found a bigger diamond in the gravels. Almost 1 carat in size. Because of this find Entwistle is noted as being the diamond capitol of Canada. Most of the lands to the south of Hwy 16 in the area have been claimed by companies prospecting for more.
