The
Qattara Depression (
Munḫafaḍ al-Qaṭṭārah) is a
depression in the north west of
Egypt in the
Matruh Governorate and is part of the
Libyan Desert. It is considered the world's largest natural
sinkhole.
[1]It lies below sea level and is covered with
salt pans,
sand dunes and
salt marshes. The region extends between latitudes of 28°35' and 30°25' north and longitudes of 26°20' and 29°02' east. Some 20 kilometres west of the depression lie the oases of
Siwa and
Jaghbub in smaller but similar depressions.
