It's been called "old reliable."

Just off Highway 12 near in Avon, Montana, when you're driving west from MacDonald Pass, there's a freshwater spring near the roadway. If you're not paying attention it might look like any other stretch of Montana highway that rolls over hills and past ranches, but at the base of a hill covered in scree is a freshwater spring that has been producing water for years.

This spring is popular. It's on public land and there's no fee for the water. You'll see that even when the Google Van was driving by people were stopped by the side of the road filling their jugs with water.

A friend who grew up in the area shared that it was a regular stop every time they drove over MacDonald Pass. Another friend says their young son calls it "Magical Mountain Water."

But is it safe to drink?
