We drove right up to Hawkeye Point. It was easy to find with a great signage.
There was a campsite with great facilities including a spacious and clean bathroom with a shower. There was a lovely covered picnic area where I had my lunch before attempting the summit.
Iowa's highest point is all of 1,671 feet coming in at the 42 highest state.
That said it is one of the nicest high-points we've been to.
The Colorado peak didn't even have a plaque even though it;s the second highest point in the continental U.S.
However, we never did find that Geological Survey Button. I think they covered up with that beautiful mosaic.
