some small plains in the state scattered over the
general hilly terrain. These plains are believed to be possibly the silted beds
of lakes which existed at the hill tops. The plains have thick layers of rich
alluvial soil. The largest of these plains is the Champhai plain, situated near
the Burma border, 150 km to the east of Aizawal. The Champhai plains are 10 km long at its widest and 5
km across. This area is now famous for cultivation of
rice which is of a very fine quality.
Another such plain is at
Vanlaiphai, which is situated 90 km away
from Aizawal towards the south-east. The plain is 10 km long and about half to
one km wide. The major part of this plain has also been converted into fields
for permanent paddy cultivation. There is another plain at Thenzawl, situated 90
km south of Aizawal.
