The Vertigo cristata has been found in northern Minnesota, northern and southwestern Wisconsin, the Upper Peninsula of Michigan, southern Ontario, Massachusetts, and some parts of British Columbia.

The snail has been reported in numerous different types of habitat such as igneous bedrock outcrops, igneous lakeshore outcrops, sandstone and carbonate cliffs, coniferous forested wetlands, and rock woodlands (Nekola 200).  The snail prefers forested areas of igneous rock and the northern white-cedar present.  There have been numerous populations found in areas with cool temperatures and at the base of open slopes (Nekola 1998).
