The Floating Bog on Dead Man's Lake |
Perched above the surrounding countryside in north central Iowa lays one of our rarest and most interesting water bodies. The small lake, of about eight acres, occupies the southwest comer of Pilot Knob State Park three miles east of Forest City. Nearly half of this lake is composed of a floating sphagnum bog which feels, if you could walk on it, feels like you are actualIy walking on an extra soft bed. Following one's normal tendency to jump up and down in one result in wet ankles, but move over a few feet returnes the sodden boots to semi-dry terrain. Then while standing still or squatting to scrutinize the green mat closely for the smaIl sun dew plant, the feet begin to sink imperceptible. Move, sink, move, and sink; again and again until the impulse to get right down among the plants can be repressed. A rare plant, the sun dew, is indigenous to this particular environment. The sun dew is a diminutive carnivorous plant related by feeding habits to the Venus flycatcher and pitcher plants. It is common in this part of the country, but only in acid, peaty areas and quite possibly Dead Man's Lake may have the sole accumulation of them in Iowa. Why Dead Man's Lake The name of the lake is another item that has aroused considerable interest. Several stories are told as one can well imagine with such a name. One tells of an early pioneer traveling to an unknown destination that passed by and drove his oxen out on the ice to let them drink. The ice gave away and the oxen, wagon, and man sank to a spongy coffin.. Another tale relates that a dead man was found on the lake shore. No one in the vicinity knew his name or the cause of his death, but many years later an ancient fowling piece was found on the same location with the root of a small tree grown through the lock. Some say he comes back when the moon is full in search of his lost wagon. The Real Reason Truth, always stranger than fiction, gives credence to
following. Before the advent of the white man in this
territory various Indian tribes wandered in Pilot Knob
and at times had headquarters there.. Sioux, Fox,
Chippewa, Sac, and Winnebago left mementoes of there
(sic) passage. After settlements reached the Winnebago
River (since dubbed Lime Creek) the Knob witnessed Indian
pilgrimages over the flatlands and rolling hills. Other Facts For those of you interested in facts and statistics.
Dead Man's Lake is only natural one in the vicinity. Its
shape is slightly like a figure eight, one loop being
open water and the other containing the island-like
sphagnum mat surrounded by marsh vegetation. Many varied
forms of bird and plant life abound there as is natural
where marshes are found. Due to the acidity of the bog
and of the lake. several species of plants are present
that are otherwise rare in Iowa.. The congregation of
birds is such that some ornithological clubs come to see
them during peak migration periods. Animal life in the
lake is quite limited. The highly acid water supports
only the species of invertebrates that are adapted to
such conditions and fish are non-existent there. A Rooted Carnivore Many animals eat plants for sustenance, but did you
know that we have a plant in our State which the reverse
is true? |
