- Arctic Ocean’s northern sea route navigable
for around 100 days in the summer, but frozen
for the other 8 months in the year. - In
summer, routes must cross the waterlogged
land and roads can be impassable. -Rivers are
used by barges in summer, but navigation is
difficult due to flooding from snowmelt and
large sandbanks that develop. - In winter, the
frozen rivers are used as ice roads for trucks,
yet there are risks of going through the ice of
hitting obstacles.
