Jezero is located on the north-western edge of Isidis Planitia, one of the largest impact basins on Mars. In its immediate vicinity, some of the oldest and most interesting geological formations and rocks on Mars can be found. The area shown here is about 18 degrees latitude and 77 degrees longitude north of the Mars equator.

Small flight guide
When approaching the crater Jezero, one first flies over the outflow channel from the east, from which the water from the lake flowed out again. Then one reaches a yellow ellipse that marks the landing site region, which measures about 10 kilometres, where the Mars 2020 rover Perseverance ("Persistence") will be set down in February 2021 with a sky crane, similar to the predecessor rover Curiosity. The ellipse partially covers the river delta, which geomorphologists refer to as the "bird foot delta" because its broad "arms" resemble the foot of a bird. Through the meandering valley Neretva Vallis, which breaks through the Karterand from the west, a river flowed until about 3.8 billion years ago, whose carried sediments formed the delta. The crater itself is now very shallow because it has been heavily backfilled by lake sediments and material brought in by the wind. Its crater rim today only rises about a thousand mater above its bottom.
