Flat Floored Crater

They start with rounded floors then progress to a flat floor resulting from a cascade of boulders that have rolled down the interior walls and settled at the bottom.

Flat floored crater. The flat portion of the floor may occur at the crater center or occur as an annulus around a central uplift synonymsflat floored impact craterdescriptionimpact craters can have a variable floor. This is the main reason why it is called a flat floored or anomalous dome crater. Such flat floors extend across the entire reach of the crater bottom or can be interrupted at the center by a central peak or peak ring. Lalande a only 8 mi.

The deep bay flat floored crater is a nearly circular lake near the south end of reindeer lake. Lofn is a shallow crater as compared to other craters of similar size. One variant of the floor morphology is a relatively flat more or less level floor. Such flat floors extend across the entire reach of the crater bottom or can be interrupted at the center by a central peak or peak ring.

Flat floored craters occur in complex craters or highly degraded or modified simple craters. In diameter located about 40 miles southwest of the crater lalande is a good example of a simple crater. Simple craters are 10 miles in diameter or less. Partially surrounding the bay is a ridge up to 100 m above the lake with a maximum diameter of 13 km which probably represents the outer rim of the crater.
