Photos never do justice to the massive monoliths in Arches; unfortunately it's just something you need to see firsthand. But that first drive into the park is fantastic; maybe that's why it's my favorite National Park, the more you go into it the more and more majestic it gets. You really feel like you're standing at the feet of frozen giants.
The Three Gossips tower 350ft above their rounded base, that's 70ft taller than the Flatiron Building in NYC, and they'd be roughly 30 stories tall if they were a building. But to see the same height done naturally in solid sandstone gives them a "weight" that no building compares to.
