I think after you hear my upcoming show you will understand why it has been reported that they close the area down and post heavily armed guards.
Lake Minnewanka is a large glacial lake five kilometres (three miles) from the town of Banff. The lake is 21 kilometres (13 miles) long and 142 metres (466 feet) deep. It is a beautiful spot, popular for picnicking, mountain biking, hiking, canoeing, diving, and snowshoeing.
For over 100 centuries, people have camped and hunted along the original shores of Lake Minnewanka. The indigenous Stoney Nakoda First Nations people called it Minn-waki (Lake of the Spirits) because they respected and feared the lake for its resident spirits. Early European settlers later named it Devil’s Lake.
