From this thread here.
But it really cannot be proven either way. 100 years ago or so somebody could have caught a few garter snakes in Canada and let them go in AK near the Stikine River. That's all it would take. Female Common Gartersnakes sometimes have 100 young at a time, but around 30 is a lot more common. Still a fast reproduction rate for any snake. But most common garter snakes are male. It's not well balanced between male and female with common garter snakes.
But the fact that the common garter snake range is continuous in that area makes be believe they are native to that area. But that is only weak evidence, not proof. Man could have extended the range. But since the Stikine River is a suitable habitat for these snakes, which is well proven by their survival there, there is no reasonable reason to believe its natural range ends before there, IMO.

That will save you another steak.I actually agree with you.
