Yosemite Valley is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California. The valley is about 7.5 miles long and 3000–3500 feet deep, surrounded by high granite summits such as Half Dome and El Capitan, densely forested with pines. The valley is drained by the Merced River, a multitude of streams and waterfalls flow into it, including Tenaya, Illilouette and Bridalveil Creeks. Yosemite Falls is the highest waterfall in North America, is a big attraction in the spring when the water flow is at its peak; the valley is renowned for its natural environment, is regarded as the centerpiece of Yosemite National Park, attracting visitors from around the world. The Valley is the main attraction in the park for the majority of visitors, a bustling hub of activity during tourist season in the summer months. Most visitors pass through the Tunnel View entrance. Visitor facilities are located in the center of the valley. There are both hiking trail loops that stay within the valley and trailheads that lead to higher elevations, all of which afford glimpses of the park's many scenic wonders.
Yosemite Valley is located on the western slope of the Sierra Nevada mountains, 150 miles due east of San Francisco. It stretches for 7.5 miles in a east–west direction, with an average width of about 1 mile. Yosemite Valley represents only one percent of the park area, but this is where most visitors arrive and stay. More than half a dozen creeks tumble from hanging valleys at the top of granite cliffs that can rise 3000–3500 feet above the valley floor, which itself is 4000 ft above sea level; these streams combine into the Merced River, which flows out from the western end of the valley, down the rest of its canyon to the San Joaquin Valley. The flat floor of Yosemite Valley holds both forest and large open meadows, which have views of the surrounding crests and waterfalls. Below is a description of these features, looking first at the walls above, moving west to east as a visitor does when entering the valley visiting the waterfalls and other water features, returning east to west with the flow of water.
The first view of Yosemite Valley many visitors see is the Tunnel View. So many paintings were made from a viewpoint nearby that the National Park Service named that viewpoint Artist Point; the view from the lower end of the Valley contains the great granite monolith El Capitan on the left, Cathedral Rocks on the right with Bridalveil Fall. Just past this spot the Valley widens with the Cathedral Spires the pointed obelisk of Sentinel Rock to the south. Across the Valley on the northern side are the Three Brothers, rising one above the other like gables built on the same angle – the highest crest is Eagle Peak, with the two below known as the Middle and Lower Brothers. To this point the Valley has been curving to the left. Now a grand curve back to the right begins, with Yosemite Falls on the north, followed by the Royal Arches, topped by North Dome. Opposite, to the south, is Glacier Point, 3,200 feet above the Valley floor. At this point the Valley splits in two, one section slanting northeast, with the other curving from south to southeast.
Between them, at the eastern end of the valley, is Half Dome, among the most prominent natural features in the Sierra Nevada. Above and to the northeast of Half Dome is Clouds Rest. Snow melting in the Sierra forms lakes. In the surrounding region, these creeks flow to the edge of the Valley to form cataracts and waterfalls. A fan of creeks and forks of the Merced River take drainage from the Sierra crest and combine at Merced Lake; the Merced flows down to the end of its canyon, where it begins what is called the Giant Staircase. The first drop is Nevada Fall. Below is one of the most picturesque waterfalls in the Valley; the Merced descends rapids to meet Illilouette Creek, which drops from the valley rim to form Illilouette Fall. They combine at the base of the gorges that contain each stream, flow around the Happy Isles to meet Tenaya Creek at the eastern end of Yosemite Valley proper. Tenaya Creek flows southwest from Tenaya Lake and down Tenaya Canyon flowing between Half Dome and North Dome before joining the Merced River.
The following falls tumble from the Valley rim to join it at various points: Yosemite Falls 2,425 feet Upper Yosemite Fall 1,430 feet, the middle cascades 670 feet, Lower Yosemite Fall 320 feet. Snow Creek Falls 2,140 feet Sentinel Falls 1,920 feet Ribbon Fall 1,612 feet Royal Arch Cascade 1,250 feet Lehamite Falls 1,180 feet Staircase Falls 1,020 feet Bridalveil Fall 620 feet. Nevada Fall 594 feet Silver Strand Falls 574 feet Vernal Fall 318 feet The features in Yosemite Valley are made of granitic rock emplaced as plutons miles deep during the late Cretaceous. Over time the Sierra Nevada was uplifted; the oldest of these granitic rocks, at 114 million years, occur along the Merced River Gorge west of the valley. The El Capitan pluton intruded the valley, forming most of the granitic rock that makes up much of the central part of the valley, including Cathedral Rocks, Three Brothers, El Capitan; the youngest Yosemite Valley pluton is the 87-million-year-old Half Dome granodiorite, which makes up most of the rock at

The David J. and May Bock Woodward House is located in the Alta Vista district of the Bexar County city of San Antonio in the U. S. state of Texas. It was designated a Recorded Texas Historic Landmark in 1994, it was placed on the National Register of Historic Places listings in Bexar County, Texas on February 16, 1996. This 2 1/2-story Classic revival home was designed 1904–1905 by architect Atlee Ayres for San Antonio business man David J. Woodward and his wife May Bock Woodward; the couple flipped twenty-three homes during their married life. David built the houses, May decorated them; each property would be sold for profit when the couple moved upward to a more expensive residence. After David Woodward died, his wife sold the house at 1717 San Pedro in 1926 to the Woman's Club of San Antonio for $47,000, it is being used as the organization's clubhouse. The first floor of the house are the interior parlor, library with fireplace, butler's pantry, kitchen, powder room and dining room; when Ayres designed the house, the second floor served as living quarters with five bedrooms and sitting room.
Alterations made by the club converted three of the bedrooms into a single meeting room. The Woodwards had it designed with window box seats, it serves as storage space. Woman's Club of San Antonio official site
