Bonneville (crater) in Utah. The strata into which Bonneville formed is thought to be loose debris, although some of the ejecta may have originated from more competent rocks. No underlying bedrock was exposed in the crater or the numerous craterlets in Bonneville's walls. The crater is relatively pristine and in particular has not been affected by water based erosion. It is likely that Bonneville is a secondary crater, given its low depth to diameter ratio. Bonneville (crater) Bonneville is an impact crater on Mars. It is located within the much larger crater Gusev. Bonneville was visited by the Mars Exploration Rover "Spirit"
