Flaugergues (crater) Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. Sometimes craters expose layers that were buried. Rocks from deep underground are tossed onto the surface. Hence, craters can show us what lies deep under the surface. Flaugergues (crater) Flaugergues is a crater in the Sinus Sabaeus quadrangle on Mars at 17° south latitude and 340.8° west longitude. It is about 245 km in diameter.
