Rock Garden (22)
A garden that mimics high, mountainous areas where rocks form a permanent part of the landscape. Boulders in the garden were carried here by the southern migration of the last glacier, the Wisconsin Ice Sheet, some 30,000 years ago. The ice sheet's journey inded in a line across Brooklyn that was wider than Long Island. Along this "terminal moraine" the glacier dumped the debris it had collected, including these rounded boulders. They are labeled based upon where their composition indicates that they came from.
