In the town of Hungry Horse, Montana is a massive dam that was created, much like the dam near my hometown, to prevent disastrous flooding to the towns that lie down river.
At 564 feet, the damn is the 10th highest in the country.
That thing. Yup, that thing right there. It's called a glory hole. *snickers* Yea, you should probably click on THIS link and learn what that is. Please mom, do not try to Google "glory hole." The photos displayed in the visitors center of this bad boy in the spring look terrifying. I must take another trip up there in late spring/early summer to see this terror in action.
Since we were "coincidentally" so close to Glacier, we had to continue our drive up the Going to the Sun Road.
