St. Valentines Day 2010

Did you know? - The elk's diet, depending on the season, is made up of eating grasses and bushes, stripping and eating the bark of aspen trees, and also eating lichens that grow on mature trees. During the spring, elk graze on different types of grasses.

In the summer, elk continue to graze on grasses, broad-leafed plants, tree leaves, and shrubs. In fall, elk will also eat mushrooms when they're available. When winter comes, elk will munch on twigs, bark, needles of trees and shrubs, and tree lichens. Elk have a four "chambered" stomach which digests this smorgasbord of food.

Elk also need water in their diet to survive. In the winter, elk eat snow. On hot summer days, elk need lots of water from streams, ponds, or other water sources. Sometimes they even dunk themselves to get rid of biting insects and to cool off.

Did you know? - A hand-held fan is an implement used to induce an airflow for the purpose of cooling or refreshing oneself. Any broad, flat surface waved back-and-forth will create a small airflow and therefore can be considered a rudimentary fan. But generally, purpose-made hand-held fans are shaped like a circle segment made of a thin material (such as paper or feathers) mounted to slats which revolve around a pivot so that it can be closed when not in use.

The movement of a hand-held fan provides cooling by increasing the airflow over the skin which in turn increases the evaporation rate of sweat droplets on the skin. This evaporation has a cooling effect due to the latent heat of evaporation of water.
