Geocache Description:

Welcome to Elizabeth Lake

The site makes the best of the Conservation District sites by staff for its unique features. This site boasts a 2 mile interpretive trail and observation deck, as well as several significant natural and archeological features.

Welcome to Elizabeth Lake

Elizabeth Lake Nature Preserve is a diverse wetland jackpot composed of graminoid bog, calcareous floating mat, graminoid fen, marsh, pond, lake, low gradient creek, sedge meadow, and dry-mesic savanna. Graminoid bog is a rare and unusual natural community, considered to be the first stage in bog succession.. Always floating above water, often in the vicinity of more open waters, this type of bog is dominated by sphagnum moss, sedges, and marsh shield fen.

Elizabeth Lake is a Kettle Lake and is considered to be the highest quality lake in McHenry County (and one of the highest in Illinois). It has 29 species of native fish, at least 200 species of plant life, 55 species of birds, 15-20 butterfly species, and 20 state endangered and state threatened species.

A kettle (or kettle hole) is a fluvioglacial landform occurring as the result of blocks of ice calving from the front of a receding glacier and becoming partially to wholly buried by glacial outwash. Glacial outwash is generated when sediment laden streams of meltwater flow away from the glacier and are deposited to form broad outwash plains called sandurs. When the ice blocks melt, holes are left in the sandur. When the development of numerous kettle holes disrupt sandur surfaces, a jumbled assemblage of ridges and mounds form, resembling kame and kettle topography. Kettle holes can also occur in ridge shaped deposits of unconsolidated rock fragments called till

A fen is further defined as a wet meadow fed by an alkaline water source such as a calcareous (containing or characteristic of calcium carbonate) spring or seep. The deposition of calcium and magnesium in the soil results in an elevated soil pH (a measure of acidity or alkalinity), and gives rise to a variety of unique plants adapted to surviving these conditions.

What is a Fen?

Fens are most commonly found in the northeast corner of the state, and in isolated areas along the Illinois River valley. Per the IL DNR, no specific classification code exists for fens, so the wetland maps cannot be used to pinpoint their location. In general, they will most often be listed as an emergent wetland. Notice that this fen may or may not share waters with the nearby "Icebox Quarry"; it mostly depends on the weather.

A bog is a wetland type that accumulates acidic peat, a deposit of dead plant material – usually mosses, but also lichens in Arctic climates. Bogs occur where the water at the ground surface is acidic, either from acidic ground water, or where water is derived entirely from precipitation.
