Triangle Lake Bog exhibits all of the attributes of a classic “kettle hole” bog. At its center is a cold deepwater lake over 35 feet in depth. Surrounding the lake are concentric communities of similar vegetation from the water’s edge to the higher surrounding landscape beyond the bog basin. At the waters edge is a floating mat of vegetation seemingly reaching across the face of the water. Leatherleaf and swamp loosestrife provide a springboard for other plants growing at the waters edge. Virginia chain fern, tawny cotton-grass, marsh fern, and several species of sedge, along with the omnipresent sphagnum mosses, are found on the raft of floating vegetation. Beyond these small plants in the meadow is a narrow ring of tamarack trees. These stately conifers are among the most unique plants in the preserve. While bearing needles and cones, they are deciduous, dropping all of their needles early each November after turning a spectacular yellow for a few days.
