Hovercraft on the Kennebec River
As part of our routine field work in the winter the staff of the Maine Office head out on Maine's frozen (and partially frozen) rivers. This is dangerous work and in 2003 the Maine Office obtained a hovercraft to allow hydrographers to access rivers with unsafe ice conditions more easily.
