If I am correct this is the Western Hognose
'Their modified rostral (nose) scale that is former in an upturned manner, makes them adept burrowers'

Meet the 'Wandering Garter' Snake
Who is Highly aquatic and rarely found far from water

A little bit of information for anyone who wants to learn...

When driving to Regina
 I stopped on the side of the highway to enjoy my snack
and read a 'Historical point of Interest' and had a Wandering Garter Snake
slither past my feet! I was evidently close to a pond or marsh
Cool!

This fine fellow is a Prairie RattleSnake
He is a highly venomous pit viper and can reach lengths up to 1.6 meters!
YIKES!
