It's about five hours from Northern Colorado to Devils Tower Monument in northeast Wyoming. You've seen it in pictures and in movies; seeing it in person is highly suggested.
In a summer of historic (and in some cases tragic) flooding in and around Yellowstone National Park, there's one moment that I can share that's been positive. Visitors to the park captured video of an elk calf successfully crossing the raging Yellowstone River.
It's funny what you can find when you're looking around the old internet. My family has visited Yellowstone's Grand Prismatic Spring many times over the years, but we never saw anything quite like this. A man shared video of the time when a "steam tornado" formed during his visit.
