Why is Meteor Crater in Arizona still visible when most impact craters created by meteorites hitting Earth are not?

The Barringer Meteor Crater near Winslow, Arizona is still very distinct and visible, when other craters are worn away, for a couple of reasons.

1. Meteor Crater is relatively young; about 50,000 years old. The worst of the "intense early bombardment", when many of the Moon's craters were formed, was 3 BILLION years ago, and those early few eons used up most of the available rocks in near-Earth space. Those craters are mostly long gone.

2. Arizona is a desert, and has been since the end of the last ice age. There are few rainstorms, no floods, not a whole lot of natural erosion going on.
