IDk... I see many snakes around where i live, and that to me might be one of many:
Hognose
Pigmy (venomous)
???
By looks of the shape of its head... Leave it alone.... I mean, you can look closer than i can, but does it have a thicker hear, like in the shape of a heart, the top butt like part of it being where the body starts, or it is a smaller, straight head, if it is a rattler, you will b able to see its tail... But yeah... cna you possilby get a close pic IF IT ISNT VENOMOUS...
