History:

This land was part of Cortlandt Manor from 1697 to 1788.  Much of the land had been bought by Van Cortlandt from native Indians.  There is evidence of  Indian life on the preserves dating back, possibly to as early as 3000 B.C.  Farming activity took place near the assemblage during the Revolutionary Period.  One story is told of a Tory who took refuge in the Indian Brook swamp and who was subsequently captured and sent to prison in Yorktown.  Tory brigoons known as "cowboys" terrorized the countryside.

The era of greater farm prosperity in this whole area began with the coming of the railroad in 1847.  General farms turned into dairy farms providing milk for NYC.  In the 1930's this farming activity declined due to the poor economy and new sanitary laws which included barn and milk house inspection and herd testing with condemnation of cattle for TB and Bangs disease.  Competition from upstate farms and the use of tank trucks to ship milk made it uneconomical for dairy farming to continue in this area.  Land values were too high to justify the use of the land for farming.  Cow country became horse country.

The land which is part of the Indian Brook Assemblage was donated to the Nature Conservancy through the generosity of several families.


Habitats:

The Marian Yarrow Nature Preserve consists of a maturing deciduous forest, one small meadow, and a stream which flows into Hidden Lake and continues to Indian Brook.  East of the lake one finds a picturesque 20 foot waterfall.  The lake is frequented by migratory birds.
