The participants in the gold rush were known as "Fifty-Niners" after 1859, the peak year of the rush and often used the motto Pike's Peak or Bust! In fact, the location of the Pike's Peak Gold Rush was centered 85 miles (137 km) north of Pike's Peak. The name Pike's Peak Gold Rush was used mainly because of how well known and important Pike's Peak was at the time. (Full article...)
Amphicoelias (/ˌæmfɪˈsiːliəs/, meaning "biconcave", from the Greek ἀμφί, amphi: "on both sides", and κοῖλος, koilos: "hollow, concave") is a genus of herbivorous sauropoddinosaur that lived approximately 150 million years ago during the Tithonian (Late Jurassic Period) of what is now Colorado, United States. An herbivore, Amphicoelias was moderately sized at about 25 m (82 ft) long–roughly the same length as Diplodocus, to which it was related. Its hindlimbs were very long and thin, and its forelimbs were proportionally longer than in relatives.
The namesake fossil of the type species Amphicoelias altus, American Museum of Natural History 5764, is uncertain in included material. When described by Edward Drinker Cope shortly after its discovery in 1877, Amphicoelias was noted to include many back vertebrae, a single pubis, and a femur. However, after purchase and cataloging of the material by the AMNH, Henry Fairfield Osborn and Charles Mook described that the specimen had only two vertebrae, a pubis, femur, tooth, scapula, coracoid, ulna and a second femur. The additional material, not mentioned by Cope, was found close in proximity to the holotype and was similar to Diplodocus, a relative of Amphicoelias. Their assignment was questioned by subsequent authors Emanuel Tschopp et al. in an analysis of Diplodocidae. (Full article...)
Henry Moore Teller (May 23, 1830 – February 23, 1914) was an American politician from Colorado, serving as a US senator between 1876–1882 and 1885–1909, also serving as Secretary of the Interior between 1882 and 1885. He strongly opposed the Dawes Act, intended to break up communal Native American lands and force assimilation of the people, accurately stating that it was directed at forcing the Indians to give up their land so that it could be sold to white settlers. Among his most prominent achievements was authoring the Teller Amendment which definitively stated that, following the Spanish–American War, the U.S. would not annex Cuba rather that the purpose of their involvement would be to help it gain independence from Spain.
