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 deep bay flat floored crater is a nearly circular lake near the south end of reindeer lake.
In diameter located about 40 miles southwest of the crater lalande is a good example of a simple crater.
Lalande a only 8 mi.
One variant of the floor morphology is a relatively flat more or less level floor.
This is the main reason why it is called a flat floored or anomalous dome crater.
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.
Flat floored craters occur in complex craters or highly degraded or modified simple craters.
Simple craters are 10 miles in diameter or less.
Flat floored craters occur in complex craters or highly degraded or modified simple craters.
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.
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.
