Ell Pond is a kettle hole in Hopkinton, Washington County, Rhode Island. It is surrounded by a swamp of red maple and Atlantic white cypress, and by steep granitic monadnocks. The small area contains communities of both hydrophytic and xeric plants, which makes it ideal for ecological research and education. It was designated a National Natural Landmark in May 1974. In 1972, The Nature Conservancy purchased 50 acres (20 ha) including the pond to extend 218 acres (88 ha) of protected land owned by the Audubon Society of Rhode Island and the 1,002 acres (405 ha) of Rockville Wildlife Management Area owned by the state. The preserve is jointly managed by all three entities. There are hiking trails in the preserve, but Ell pond is specifically not reachable due to its fragile environment.
A kettle is a depression/hole in an outwash plain formed by retreating glaciers or draining floodwaters. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating a dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake. When the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than 10 m (33 ft) deep and eventually fill with sediment. In acid conditions, a kettle bog may form but in alkaline conditions, it will be kettle peatland.

The Tannersville Cranberry Bog or Cranberry Swamp is a sphagnum bog on the Cranberry Creek in Tannersville, Pennsylvania. It is the southernmost boreal bog east of the Mississippi River, containing many black spruce and tamarack trees at the southern limit of their ranges. Technically, it can be classed as an acid fen, as it receives some groundwater flow. The site was designated a National Natural Landmark in December 1974. It was purchased by The Nature Conservancy and the Conservation and Research Foundation in 1957. Like many bogs, its terrain presents an image of solidity, but a liquid mass of decaying peat lies beneath a six-inch (152 mm) layer of sphagnum and a network of supporting tree roots. However, this bog may be viewed from a floating walkway.
