Hebron is notably at once a nexus between valley regions within the 'Great Valley', and also between mountain regions. The nexus of the Champlain and Hudson Valleys (described in greater detail below in the paragraph on watersheds) is located here. The taller peaks of the Taconics are on the Vermont side of the border, and begin to dwindle comparatively into foothills in Hebron. Hebron can be described as the foothills between the Adirondack Mountains of New York, and the Taconic and Green Mountains of Vermont. Hebron thus is at once at a high point dividing valleys, and a lowlands dividing mountain areas. In an era of much water pollution, it is a good thing to be at the top end of watersheds. Hebron's battles with water quality are internal rather than related to problems upstream.
