Downslope winds in the Sierra Nevada mountains are meteorological phenomena that greatly influence the region's weather patterns and local ecosystems. These winds often occur when air descends rapidly down the eastern slopes of the Sierra Nevada range. As the air moves from higher elevations to lower elevations, it compresses and warms due to adiabatic heating, which leads to significant temperature increases over short distances.

One of the most notable downslope winds in this region is the "Tahoe Gap Wind," which occurs around Lake Tahoe. During periods of high pressure and clear skies, cool air from the Sierra Nevada's western slopes accelerates downslope, funneling through gaps in the mountain range. This wind can be strong and gusty, affecting local weather conditions by quickly...

For years, fires in our forests have been extinguished as soon as possible. That practice, when combined with warmer temperatures, and drier conditions, has made for larger and more intense fires. In fact, new words have been coined to better describe the immensity of recent fires; a megafire is being used to describe 100,000 acre blaze, and anything over that becomes a gigafire. For perspective, 100,000 acres equals a little over 156 square miles.

Many recent studies have shown that a forest is more that just a stand of trees. It is a thriving ecosystem, with fire an important part. For instance, neither sequoia nor redwood trees can reproduce without fire. Native Americans knew about the need for fire. What colonists thought of as a pristine, untouched wilderness was the...

Fleas and ticks may not be common in the Tahoe Basin, nonetheless, they are here — living here, some even thriving here. Don't believe anyone who tries to tell you otherwise.

In the Sierra Nevada mountains, fleas are commonly associated with rodents; squirrels, chipmunks, and mice, which serve as the primary hosts. Other animals, like deer, or just about anything with fur, can also host fleas.

The most common species of fleas in the Tahoe Basin is the cat flea. Despite its name, the cat flea is an equal opportunity feeder, not differentiating between cats, or dogs, or humans. Anyone, or anything, is fair game to a flea.

Although a rare occurrence, fleas can transmit disease to both animals and humans. Disease aside, flea bites can cause itching, irritation, or allergic reactions in humans.

Small and wingless as they are, fleas can be found in wooded areas, grasslands and even residential neighbo...

Stand on any vista point overlooking Lake Tahoe, and you will be captivated by the seeming serenity of that big blue lake in front of you. That's why it's hard to believe you are really looking at a perpetual motion machine.

Lake Tahoe has as many as 63 tributaries pouring their fresh water into the lake, nourishing it with a constant influx of new water, and enriching its deeper water with nutrients. After the water swirls around the lake for a bit, it eventually hits the Truckee River, the lake's only outflow, which flushes water downstream, insuring renewed vitality.

Almost everyone knows where the Truckee River meets the Lake. Though, many do not know the locations of tributari...

Everyone loves quaking aspen trees. From the photographers who delight in the aspen's fall displays, to deer munching on the nutritious fallen autumn leaves, to beavers using aspens as both dam building material and food, the tree seems to have something for all.

The tree gets its name because the slightest breeze causes the leaves to tremble, or quake. One group of native Americans called the quaking aspen "nut-kie-e," which translates to noisy leaf.

During most seasons of the year, quaking aspen trees fade into the green of the forests. But come autumn, the aspen's intense golden hues rival the sunshine. Then, all kinds of cameras are brought out to record the display.

This widespread, well known tree ranges across the U.S. from Maine to the California mountains, as well as from Minnesota to New Mexico. The rangy aspen was declared the state tree of Utah.

An aspen in Utah holds the title...
