The city of Boulder, Colorado takes its spelling from Boulder Creek, a waterway well known for its gigantic boulders. The word boulder enters the English language in the 1300s from the Swedish word bullersten, which means noisy stone, presumably from the sound of roaring water rushing around a large stone in a stream.
