An introduction to water moccasin

Even non-venomous watersnakes will bite, so the best policy for dealing with snakes is to "leave them be" to play their important roles in our ecosystem. Best ways to tell watersnakes and Water Moccasins apart: A harmless snake the same length would be much more slender and would have a much longer, thinner tail see below. The body of this young, venomous Water Moccasin is very thick for its length, and has a relatively short, thick tail.

In its natural state, the valley floor was marshy and often flooded in the spring when snow melt in the high Sierra cascaded down the Tuolumne River and backed up behind the narrow gorge which is now spanned by O'Shaughnessy Dam. The Hetch Hetchy Road drops into the valley at the dam, but all points east of there are roadless, and accessible only to hikers and equestrians.

The waterfall on the Tuolumne is now submerged under Hetch Hetchy Reservoir. About one million years ago, the extensive Sherwin glaciation widened, deepened and straightened river valleys along the western slope of the Sierra Nevada, including Hetch Hetchy, Yosemite Valley, and Kings Canyon farther to the south.

This is because the Tuolumne catchment basin above Hetch Hetchy is almost three times as large as the catchment area of the Merced River above Yosemite, allowing a greater volume of ice to form. Gray pineincense-cedarand California black oak grow in abundance.

Many examples of red-barked manzanita can be seen along the Hetch Hetchy Road. Spring and early summer bring wildflowers including lupinewallflowermonkey flowerand buttercup. Seventeen species of bats inhabit the Hetch Hetchy area, including the largest North American bat, the western mastiff.

Due to large cataracts on the Tuolumne River upstream, Hetch Hetchy Valley may have been in the uppermost range for native rainbow trout in the river.

Water Moccasin Information & Facts

They would light upon a man's blue shirt and turn it brown, and were voracious as mosquitoes would be. Native American cultures were prominent before the s when the first settlers from the United States arrived in the Sierra Nevada.

The valley provided an escape from the summer heat of the lowlands. Today, descendants of these people still use milkweeddeergrassbracken fernwillowand other plants for a variety of uses including baskets, medicines, and string. For thousands of years, Native Americans subjected the valley to controlled bushfires, which prevented forest from taking over the valley meadows.

In the 19th century, the first white visitors to the valley did not realize that Hetch Hetchy's extensive meadows were the product of millennia of management by Native Americans; instead they believed "the valley was purely a product of ancient geological forces or divine intervention This was likely because of Hetch Hetchy's narrow outlet, which in years of heavy snowmelt created a bottleneck in the Tuolumne River and the subsequent flooding of the valley floor.

Miners did not stay in the area for long, however, as richer deposits occurred further south along the Merced River and in the Big Oak Flat area. Hoffman of the California Geological Survey conducted the first survey of the valley.

Hoffman observed a meadow "well timbered and affording good grazing", and noted the valley had a milder climate than Yosemite Valley, hence the abundance of ponderosa pine and gray pine. Those who did visit it were enchanted by its scenery, but encountered difficulties with the primitive conditions and, in summertime, swarms of mosquitoes.

Bierstadt described the valley as "smaller than the more famous valley As the grazing of livestock damaged native plants in the Hetch Hetchy Valley, mountaineer and naturalist John Muir pressed for the protection of both valleys under a single national park.

Proponents of the dam replied that out of multiple sites considered by San Francisco, Hetch Hetchy had the "perfect architecture for a reservoir", [43] with pristine water, lack of development or private property, a steep-sided and flat-floored profile that would maximize the amount of water stored, and a narrow outlet ideal for placement of a dam.

Muir predicted that this lake would create an unsightly "bathtub ring" around its perimeter, caused by the water's destruction of lichen growth on the canyon walls, [44] which would inevitably be visible at low lake levels. Since the valley was within Yosemite National Parkan act of Congress was needed to authorize the project.

Congress passed and President Woodrow Wilson signed the Raker Act inwhich permitted the flooding of the valley under the conditions that power and water derived from the river could only be utilized for public interests.Dealing with Snakes in Residential Areas Introduction (to the series) Identifying Commonly Encountered Snakes; Preventing Encounters; Emergency Planning; Dealing with Venomous Snakes in Schoolyards habitats where they are commonly found, what they eat, and more.
