Travel back in time to explore the world of the Champlain
Valley when the Adirondack Mountains were as high as the
Himalayas or to the time when beluga whales and seals swam
in the salty waters of the Champlain Sea. Pick up a sea
star, build your own mountain or try your hand at eroding
mountain rocks. These activities and much more await your
explorations as you uncover the mysterious time Before the
Basin.
