Snowden, Saskatchewan Canada 1970/71

My dad had a farm south of Snowden a couple of miles south,my uncle had a quarter of land beside my dad's land he also had more land around Melfort Sask.My uncle was just north of us we could see very easily.
My uncle had been up for a few days preparing the land and got it all seeded then headed back to his other land no doubt to seed there also
The next day I caught out of the corner of my eye what looked like somebody walking across my uncles seeded land
I called my mother and she came and looked..I said to her do you see it,she said yes I said to her who is it ? she said I don't know ! I was thinking it could be a bigfoot it was dark, tall my guess seven feet could of been more I don't know
I wanted to check for tracks but never too scared didn't want to risk getting the car stuck has I knew the land was soft in the area...I viewed it all about a third of a mile away visually only, didn't have binoculars and time was limited.Thanks for allowing me to post and get it off my chest
