Seventeen Mile House

The Seventeen Mile House is a historic site and open space located at 8181 S. Parker Rd. in Centennial, Colorado. It is a 33-acre former stagecoach stop with a square log structure covered with clapboard. It was a stopping place during the 1800s along the Smoky Hill Trail. It is one of the last two remaining trail houses left on the trail. Mary Hightower was the original owner of the house, having moved there in 1866. It was almost torn down in 1977 until negative publicity stopped it from happening. The site was zoned for commercial development until the County of Arapahoe acquired the land in 2001. History The first Colorado Gold Rush in 1858-1859 began an influx of horse and wagon traffic to Denver, and two of the routes were the historic Smoky Hill Trail from Kansas and Cherokee Trail from Oklahoma. Six way stations sprang up along Cherry Creek, serving travelers in the final stretch into Denver after the two trails merged. Railroad service reached Denver in 1870, and the wagon trails gradually fell into disuse. Seventeen Mile House closed and became a working farm alongside the Cherry Creek River by the 1880s. It is one of two surviving Way Stations. The stations were named according to how many miles each site is from downtown Denver's intersection of Colfax and Broadway. Four Mile House is the other way station still standing. Current Site and Future Plans In 2001, local historic and preservation groups worked together to acquire the property for Arapahoe County. Arapahoe County has a 2007 Master Plan for Seventeen Mile House serving as vision and roadmap. Today the site is an Open Space park administered by Arapahoe County, Colorado, with the Cherry Creek Valley Historical Society giving monthly open house tours, and involved in preservation and development. An annual Fall Festival has been held in recent years. This Open Space borders two other Open Spaces, thus contributing to a regional corridor for wildlife areas and biking/hiking trails along the Cherry Creek Valley, which includes Denver's extensive Cherry Creek Reservoir State Park.

Sidewinder (Elitch Gardens)

Sidewinder is a steel roller coaster located at Elitch Gardens in Denver, Colorado. This is a fairly simple coaster that takes rides through one loop. Instead of starting from the ground, riders have to ascend stairs fifty feet up to the loading station. The train is launched down a hill, goes into the loop, then ascends a slope opposite of the station with a braking section. The train repeats the layout backwards, and returns to the station. Before being operated at Elitch Gardens this roller coaster was at the Magic Springs & Crystal Falls amusement park as the Roaring Tornado. The coaster operated at the original Elitch Gardens from 1990 to 1994, then was relocated to the current Elitch Gardens in 1995. It is one of only three Arrow Dynamics launched loop coasters to be operating around the world, the others being Diamond Back at Frontier City, and the Revolution at Blackpool Pleasure Beach. The ride has received new paint for the 2010 season, and is now more of a lime green than the darker shade it has been since being repainted from its original white. In 2014, riders were trapped after mechanical issues stopped the ride. In 2025, the ride was reopened after two years of closure. References
Silver Cliff Cemetery

Silver Cliff Cemetery is a cemetery established in the early 1880s outside Silver Cliff, Colorado, about a mile south of State Highway 96 on Mill Street (County Road 340). Background Silver Cliff Cemetery is split into two sections, one half for Catholic burials and the other half, known as the Cross of the Assumption Cemetery, for Protestant burials. The cemetery is still in use today and is owned and operated by the Town of Silver Cliff. Lights The cemetery is noted for reports of "dancing blue lights" seen on occasion around the cemetery at night. The lights, which according to reports look like blue lantern lights or white spheres, are said to float through the cemetery and bounce on the headstones. These effects have been reported since the 1880s. The lights were featured in the August 1969 National Geographic Magazine, Volume 136, No. 2. These lights were seen for the first time by a group of miners who took the cemetery as a shortcut to get to the town more quickly. But the miners got lost and later saw the lights appearing. Word of the lights spread, and as the lights became famous more people became more interested in the cemetery. Some people say these lights are a normal phenomenon called "Wildfire", which normally appears in swamps and wet places. Researcher and writer Karen Stollznow investigated the cemetery, and wrote that there were several possible natural explanations for the coloured lights, such as a receptor on the retina of the eye sensitive to the colour blue, or the effect of phosphenes, brief flashes of light perceived by the eye, sometimes induced by eye movements, "which would also explain the lights “dancing”, “floating” or “darting” across the cemetery." Stollznow reports that not all visitors see the lights, supporting her conclusion that "seeing lights during darkness in Silver Cliff Cemetery is a personal experience, likely caused by a person’s eyes and mind after they have spent many hours determined to “see” something."

Cementerio de Silver Cliff

El cementerio de Silver Cliff es un camposanto, aún en uso, establecido a principios de la década de 1880 a las afueras de Silver Cliff, un pequeño pueblo del condado de Custer, en el estado de Colorado (Estados Unidos). Se ubica a poca distancia al sur de la carretera estatal (State Highway) 96.​​ Se encuentra dividido en dos secciones, una para entierros católicos y otra para protestantes. Desde el siglo XX, con medio siglo de historia a sus espaldas, el cementerio comenzó a ser conocido por ser objeto de informes que hablaban de "luces azules danzantes" que ocasionalmente se veían flotar en los alrededores ya de madrugada. Dichas luces, que según los informes parecen linternas azules o esferas blancas, flotan por el cementerio y rebotan en las lápidas. Las luces aparecieron en la revista National Geographic, en su volumen 136 de agosto de 1969.​​ Estas luces fueron vistas por primera vez por un grupo de mineros que tomaron el cementerio como un atajo para llegar a la ciudad más rápidamente. Pero el grupo acabó perdiéndose y vieron aparecer las luces. Se corrió la voz de los hechos, y a medida que iban haciéndose famosas por los diversos episodios que se sucedían, más personas se interesaron más en el cementerio. La investigadora escéptica Karen Stollznow investigó el cementerio y escribió que había varias posibles explicaciones naturales para las luces de colores, como un receptor en la retina del ojo sensible al color azul, o el efecto de los fosfenos, breves destellos de luz percibidos por el ojo, a veces inducido por movimientos oculares, lo que explicaría el particular "baile" de las luces a través del cementerio. Stollznow informa que no todos los visitantes logran ver las luces, lo que respalda su conclusión de que "ver luces durante la oscuridad en Silver Cliff es una experiencia personal, probablemente causada por los ojos y la mente de una persona después de pasaar muchas horas "decidida a ver algo".​ Referencias Enlaces externos

WWV

WWV er en amerikansk kortbølge-radiostation ved byen Fort Collins i Colorado. Den er bedst kendt for sine regelmæssige udsendelser af tidssignaler, der har været sendt siden 1945. Stationen bruges også til fastsættelse af standarder for den amerikanske regerings officielle frekvenser. WWV drives af det amerikanske regeringsinstitut National Institute of Standards and Technology (NIST), mere specifikt dets Time and Frequency Division, som indgår i NIST's Physical Measurement Laboratory i Gaithersburg i Maryland. WWV blev oprettet i 1919 af det amerikanske standardiseringsorgan "Bureau of Standards". Det er en af de ældste stadig transmitterende radiostationer i USA. 1. oktober 2019 fejrede NIST WWV's hundrede-årsjubilæum. I 1931 flyttede stationen til den første af tre beliggenheder i Maryland. I 1966 flyttede den til sin nuværende placering nær Fort Collins. NIST driver en lignende kortbølgestation, WWVH på Kauai på Hawaii. Både WWV og WWVH offentliggør den officielle UTC-tid hver minut og andre vigtige data på timebasis, herunder status for Global Positioning System (GPS)-satellitkonstellationer. Fordi begge stationer transmitterer samtidig på de samme frekvenser anvender WWV en mandsstemme for at kunne blive adskilt klart fra WWVH, som betjener sig af en kvindelig stemme. Kilder
WWV (station de radio)

WWV est l'identifiant de la station de radio du NIST basée à Fort Collins, Colorado. Sa principale fonction est d'émettre en continu le temps universel coordonné et un étalon de fréquence. La station envoie l'heure simultanément sur cinq fréquences : 2,5 MHz, 5 MHz, 10 MHz, 15 MHz et 20 MHz. Ces fréquences ainsi que le signal horaire sont dérivés d'un ensemble d'horloges atomiques situées sur le site. WWV est associé à WWVH, localisé à Hawaï. Sur le même site, à Fort Collins, se trouve la radio WWVB. WWV est la plus vieille station de radio émettant en continu aux États-Unis, d'abord depuis Washington en mai 1920. Elle s'est installée à Fort Collins le 1er décembre 1966, permettant la réception permanente du signal sur toute la partie continentale des États-Unis, ainsi que sur les zones océaniques selon la propagation. Utilisation La station WWV, ainsi que d'autres émetteurs de temps, a été un auxiliaire précieux à la navigation maritime, en permettant le recalage précis des horloges, nécessaire pour la navigation astronomique. Pour cet usage, l'heure est transmise en clair à chaque minute, suivie d'un top horaire d'une seconde à 1 000 Hz. Les fréquences porteuses peuvent être reçues sur la terre entière selon la propagation et permettent de caler avec précision les récepteurs de trafic, en particulier la fréquence 15 MHz en Europe. L'émetteur WWV s'identifie en clair deux fois par heure, lors des première et trente-et-unième minute, permettant de s'assurer de la porteuse utilisée. Le message commence ainsi : "National Institute of Standards and Technology Time. This is radio station WWV, Fort Collins, Colorado, ..." Pour les usages automatisés, un code inaudible de type IRIG-B est également transmis en permanence. L'émetteur transmet également les informations de propagation HF, les alarmes GPS, ainsi que les avis de tempête. Le signal de WWV peut également être consulté par téléphone en appelant le +1-303-499-7111. Les appels téléphoniques sont limités à deux minutes de longueur et le signal est en moyenne en retard de 30 millisecondes.

Smuggler-Union Hydroelectric Power Plant

The Smuggler-Union Hydroelectric Powerplant, also known as the Bridal Veil Powerhouse, is an electric power generation plant and residence located next to Bridal Veil Falls on a 400-foot (120 m) cliff overlooking Telluride, Colorado. The structure is 2+1⁄2 stories on a poured concrete foundation with a wood frame superstructure. It consists of a main power plant building, a 1+1⁄2-story residence and a 1-story cookhouse. The power plant foundation is distinctive, with semicircular windows. A semicircular bay with arched windows projects out on a rock spur. History The Smuggler-Union Hydroelectric Powerplant was built to power the Smuggler-Union Mine 2,000 feet (610 m) below in 1907, providing alternating current for industrial purposes. The plant was proposed by Smuggler-Union Mine manager Buckley Wells who lived in the residence as a summer home until the 1920s. It was originally accessed in winter by an aerial tramway but that was eventually destroyed. It operated in its original configuration until its decommissioning in 1953, serving the Idarado Mining Company. The living quarters and especially the power house/generator fell into disrepair and were heavily vandalized by the time of the historic registry survey in 1979. A local resident, Eric Jacobson, acquired a 99-year lease from the Idarado Mining Company for the property in 1988 and proceeded to restore the building and its hydroelectric facility and eventually moved his family into the residence, raising three children at the precarious home. Jacobson restored the AC plant to operation in 1991 with power being generated by its original 2300 volt Westinghouse Electric AC generator, one of the oldest AC generators in operation. In 2010 Jacobson gave up the lease to the Idarado Mining Company citing continual regulation and legal problems associated with the site. Idarado has not kept the plant in operation, depriving the community of this readily available source of renewable power generation. As of 2012, under Jacobson's care, the plant generated approximately 2,000 megawatt hours per year – enough electricity to power about 2,000 average American homes – which was purchased from Jacobson by the local San Miguel Power Association. Because the Bridal Veil Hydroelectric Power Plant is over 100 years old, restoring the generator to operation is a difficult feat. The Smuggler-Union Powerplant was placed on the National Register of Historic Places on December 27, 1979.

The Grade Point Average (GPA) system was introduced. In the 1976-1977 school year, the first Cannon Game was held, with the Colts winning the cannon 27-21. In the 1981-1982 school year, a horseshoe statue was gifted to the school that is currently at the front of the school. In the 1988-1989 school year, the auditorium received a $170,000 renovation with the first musical to be hosted with the new equipment being "Once Upon A Mattress". A mock election was held, with the results predicting a George Bush victory. In the 1989-1990 school year, 250 students protested against the school's attendance/tardy policy. Landscaping around the school was completed and a girls' softball team was formed. References External links Official website
ADX Florence

L'ADX Florence (abreviatura d'United States Penitentiary Administrative Maximum Facility) és una presó federal de màxima seguretat dels Estats Units d'Amèrica. S'ubica prop de Florence, a l'estat de Colorado, dins d'un complex que acull altres presons amb una categoria de seguretat inferior. La presó de Florence acull alguns dels interns estatunidencs considerats més perillosos i és l'única penitenciaria federal amb la consideració de "supermàxima seguretat", significant que es prenen mesures extremes de control i es limita al màxim l'autonomia dels presoners. El complex ha estat anomenat l'«Alcatraz de les Muntanyes Rocoses». Condicions de vida Els interns a les institucions de "supermàxima seguretat" romanen tot el dia tancats a les seves cel·les individuals i només poden sortir una o dues hores per a fer exercici físic dins d'un recinte interior. No els és permès mantenir cap contacte amb altres presoners ni la realització d'activitats comunitàries. Tampoc no poden comunicar-se amb l'exterior mitjançant el telèfon o qualsevol altre dispositiu. Quasi tots els mobles de les cel·les són de formigó, inclosos els armaris, l'escriptori i el llit. Cada cel·la disposa d'un urinari metàl·lic, una pica i una dutxa amb limitador de temps per a evitar inundacions. Les finestres són franges estretes que permeten l'entrada de llum natural però no esbrinar la ubicació de la cel·la dins del complex penitenciari. Les cel·les poden tenir ràdio i un televisor emetent programes d'entreteniment, educatius i religiosos, però sempre són controlats des de l'exterior i els funcionaris poden desconnectar-los com a mesura de disciplina. Les instal·lacions de l'ADX Florence disposen de nombroses càmeres de seguretat i sensors de moviment així com de 1.400 portes blindades controlades remotament. Interns destacats Zacarias Moussaoui, condemnat per formar part de la xarxa terrorista que realitzà els Atemptats de l'11 de setembre de 2001. Theodore Kaczynski, l'anomenat Unabomber, efectuà l'enviament de diversos paquets-bomba per a protestar contra la societat actual i l'abús de la tecnologia. Timothy McVeigh, realitzador de l'Atemptat d'Oklahoma City. Fou reclòs a Florence fins que el traslladaren al corredor de la mort de la presó de Terre Haute. Terry Nichols, condemnat per col·laborar amb Timothy McVeigh. Referències Enllaços externs Web de l'Agència Federal de Presons dels EUA sobre l'ADX Florence Arxivat 2012-08-08 a Wayback Machine.
