Eye on the Outdoors
Eye on the OutdoorsAn angler’s tale of change in the natural world
Bob Ballantyne
POSTED: June 14, 2010
Fact BoxNatural factsWater trapped in cracks and crevices in rock formations freezes in winter. Since water expands when it freezes, it forms a powerful wedge that fractures rocks both large and small. Water tends to wear rocks down to smaller and smaller particles creating sand and silt. This material acts like an abrasive when captured by flowing water and wears down other rocks in streams. Microscopic organisms not only attack dead trees. Wood-inhabiting microbes and living trees interact in a long and intense struggle for survival. While the act of clear-cutting forests receives criticism, the change it brings in habitat favors many important species, and not just game animals. The technical difference between a lake and a pond is in depth. A lake is deep enough to have an area where photosynthesis cannot occur because of lack of sunlight. Photosynthesis can occur everywhere in a pond.
A June campsite that supports an annual jaunt to Bradford County is located high on a mountain flat and on the shoreline of that county’s publicly owned Sunfish Pond. |
