Echo Mountain
Echo Mountain is a mountain promontory of the San Gabriel Mountains, in the Angeles National Forest above Altadena, in Los Angeles County, California. Geography Echo Mountain was shaped from an alluvial fan between Rubio and Las Flores canyons. It is geographically defined by Castle Canyon to its leeward side, Rubio Canyon at its foot, and Las Flores Canyon on its windward side. Echo has a mean elevation of . It is most visible as a short mountain extension whose ridge protrudes below the peak of Inspiration Point. Echo Mountain's name is derived from the number of repetitions one's voice could emit into Castle Canyon. Boy Scout projects were made to find the "sweet spot" where the largest number of repetitions could be heard. During the days of the Mount Lowe Railway "echophones" were set up to assist in voice projections near the best sweet spots. History On 6 January 1993, Echo Mountain, also referred to as Mount Echo, was delineated as part of the Mount Lowe Railway m ...

Windward And Leeward
Windward () and leeward () are terms used to describe the direction of the wind. Windward is ''upwind'' from the point of reference, i.e. towards the direction from which the wind is coming; leeward is ''downwind'' from the point of reference, i.e. along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side". If the vessel is heeling under the pressure of crosswind, the lee side will be the "lower side". During the Age of Sail, the term ''weather'' was used as a synonym for ''windward'' in some contexts, as in the ''weather gage''. Because it captures rain, the windward side of a mountain tends to be wet compared to the leeward it blocks. Origin The term "lee" comes from the middle-low German word // meaning "where the sea is not exposed to the wind" or "mild". The terms Luv and Lee (engl. Windward and Leeward) have been in use since the 17th century. Usage Windward and leeward directions (and the points o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Avenue (Pasadena)
Lake Avenue is a major north–south feeder road for the Pasadena and Altadena communities in Los Angeles County, California. The road was developed in the mid 19th century and takes its name from a lake which was located at its southernmost end known variously as Mission Lake, Kewen Lake, and Wilson Lake reflecting different owners of the land. The lake bed still exists as a municipal park (Lacy Park) in the City of San Marino just south of the Raymond Dike, but it holds no water. It has been surrounded by residences who are served by a crisscross set of roads that dip into the edges of impression and back out the other side. Lake Avenue is approximately in length. Transportation Metro Local line 662 and Pasadena Transit line 20 run on Lake Avenue: the former starts at Del Mar Boulevard and the latter through most of Lake Avenue between California Boulevard and Woodbury Road. A Metro L Line station is located at Interstate 210 under Lake Avenue. In Altadena The northe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sam Merrill Trail
The Sam Merrill Trail is a major hiking trail in the Las Flores Canyon of the San Gabriel Mountain Range north of Altadena, California, which leads to the top of Echo Mountain. It was built by Charles Warner and the Forest Conservation Club of Pasadena during the 1930s. After the deluge of 1938 most of the trails that accessed the mountain sides around Echo Mountain and the Mount Lowe Railway had been all but washed away. Sam Merrill found it important to maintain public hiking access to the railway ruins and other portions of the treacherous foothill. During the 1940s he overhauled and maintained the trail. As a young man Merrill had lived with John Muir for a summer, which inspired a lifetime commitment to the outdoors and the Sierra Club. Merrill, who served as Clerk of the Superior Court of Los Angeles, was an active volunteer in the Sierra Club, leading outings for almost twenty years, serving on the Executive Committee of the Angeles Chapter from 1926 to 1935 and on t ...

Funicular
A funicular (, , ) is a type of cable railway system that connects points along a railway track laid on a steep slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echo Phone
In audio signal processing and acoustics, an echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener. Typical examples are the echo produced by the bottom of a well, by a building, or by the walls of an enclosed room and an empty room. A true echo is a single reflection of the sound source. The word ''echo'' derives from the Greek ἠχώ (''ēchō''), itself from ἦχος (''ēchos''), "sound". Echo in the Greek folk story is a mountain nymph whose ability to speak was cursed, leaving her able only to repeat the last words spoken to her. Some animals use echo for location sensing and navigation, such as cetaceans (dolphins and whales) and bats in a process known as echolocation. Echoes are also the basis of Sonar technology. Acoustic phenomenon Acoustic waves are reflected by walls or other hard surfaces, such as mountains and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Lowe Railway
The Mount Lowe Railway was the third in a series of scenic mountain railroads in the United States created as a tourist attraction on Echo Mountain and Mount Lowe, north of Los Angeles, California. The railway, originally incorporated by Thaddeus S. C. Lowe as the Pasadena and Mt. Wilson Railroad Co., existed from 1893 until its official abandonment in 1938, and was the only scenic mountain, electric traction ( overhead electric trolley) railroad ever built in the United States. Lowe's partner and engineer was David J. Macpherson, a civil engineer graduate of Cornell University. The Mount Lowe Railway was a fulfillment of 19th century Pasadenans' desire to have a scenic mountain railroad to the crest of the San Gabriel Mountains. The Railway opened on July 4, 1893, and consisted of nearly of track starting in Altadena, California, at a station called Mountain Junction. Atop Echo Mountain was a 70-room Victorian hotel, the Echo Mountain House. A short distance away stood the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvial Fan
An alluvial fan is an accumulation of sediments that fans outwards from a concentrated source of sediments, such as a narrow canyon emerging from an escarpment. They are characteristic of mountainous terrain in arid to semiarid climates, but are also found in more humid environments subject to intense rainfall and in areas of modern glaciation. They range in area from less than to almost . Alluvial fans typically form where flow emerges from a confined channel and is free to spread out and infiltrate the surface. This reduces the carrying capacity of the flow and results in deposition of sediments. The flow can take the form of infrequent debris flows or one or more ephemeral or perennial streams. Alluvial fans are common in the geologic record, such as in the Triassic basins of eastern North America and the New Red Sandstone of south Devon. Such fan deposits likely contain the largest accumulations of gravel in the geologic record. Alluvial fans have also been found on Mar ...
