Pine Island is on a south-flowing part of the North Saskatchewan River, about 50 km east of Lloydminster.
In 1792 Isaac Batt, a moderately well-known trader, went south with a group of Indians to hunt on the prairie and was murdered by them.
The island is not easily accessible, but in 1991 a memorial stone and plaque were erected on the river bank.
As of September 2014, the plaque is still in place on top of high hill overlooking Pine Island.
Morton mentions an unnamed NWC post occupied by Edward Umfreville directly north of Maidstone and a house belonging to Donald McKay a hundred yards away.
