Tarryall Creek is a tributary of the South Platte River, approximately 68.5 mi long, in Park County in central Colorado in the United States.
 It drains a rural portion of north and central South Park, an intermontane grassland in the Rocky Mountains southwest of Denver.
 It rises in the high Rockies in several forks along the Continental Divide in the Pike National Forest southwest of Boreas Pass.
 It descends to the southwest through a short canyon, emerging into South Park near Como, Colorado.
 It crosses U.S. Highway 285 east of Red Hill Pass northeast of Fairplay, the county seat of Park County, then meanders towards the southeast, joining the South Platte from the east in the southeastern corner of South Park.
Elk Park Pass, elevation 6352 ft , is a mountain pass on the Continental Divide in southwestern Montana, about 4 mi northeast of Butte.
 It is traversed by Interstate 15 and is one of three crossings of the Divide by the Interstate (all in Montana), the others being Monida Pass (on the border with Idaho) and Deer Lodge Pass southwest of Butte.
 Elk Park Pass lies on the border between Silver Bow and Jefferson counties and is remarkable for its highly asymmetrical nature.
 The approach from the north is through namesake Elk Park, a high, mostly treeless plain (like South Park in Colorado or the Sierra Valley in California), and the grade is almost imperceptible.
 The elevation at the northeast end of the park, about 10 mi from the pass, is about 6200 ft , only 152 ft lower than the pass itself.
 However, at the south end, the highway drops 750 ft from the pass into Butte over a distance of only about 4 mi .
The Denver, South Park, and Pacific Railroad (later called the Denver, Leadville and Gunnison Railway) was a historic narrow gauge railroad that operated in Colorado in the western United States in the late 19th century.
 The railroad opened up the first rail routes to a large section of the central Colorado mining district in the decades of the mineral boom.
 The railroad took its name from the fact that its main line from Denver ascended the Platte Canyon and traversed South Park.
 Founded in 1872 by Colorado Governor John Evans, the company was purchased by the Union Pacific Railway in 1880, though it continued to be operated independently.
 The line went bankrupt in 1889 and was reorganized under the new moniker the Denver, Leadville and Gunnison Railway.
 When the Union Pacific went bankrupt in 1893, the DL&G lines went into receivership and were eventually sold to the Colorado and Southern Railway.
 In the first half of the 20th century, nearly all the company's original lines were dismantled or converted into .
 The last train to run the old DSP&P tracks was from Como, Colorado on April 11, 1937.
 A section of the standard gauge line between Leadville and Climax is still operated as a passenger excursion railroad called the Leadville, Colorado and Southern Railroad.
 At its peak the Denver, South Park and Pacific Railroad had 335 mi of narrow gauge line, making it the largest narrow gauge railroad in the state of Colorado.
Jerome "Chef" McElroy is a cartoon character on the Comedy Central series "South Park" who was voiced by soul singer Isaac Hayes.
 A cafeteria worker (as his nickname implies) at the local elementary school in the town of South Park, Colorado, Chef is generally portrayed as more level-headed than the other adult residents of the town, and sympathetic to the kids.
 His guidance is often sought by the show's core group of child protagonists – Eric Cartman, Stan Marsh, Kyle Broflovski, and Kenny McCormick – as he is usually the only adult whom they consistently trusted.
 To an inadvertent fault, he frequently gives inappropriate advice, usually in the non sequitur form of a lascivious soul song.
"Cartman's Mom Is a Dirty Slut" is the first season finale of the American animated television series "South Park".
 It originally aired on Comedy Central in the United States on February 25, 1998.
 The episode is the highest viewed episode in the entire "South Park" series, with 6.4 million views.
 It is part one of a two-episode story arc, which concluded with "Cartman's Mom Is Still a Dirty Slut".
 The episode follows Eric Cartman, one of the show's child protagonists, becoming curious about the identity of his father.
 He discovers that his father is most likely a man his mother had sexual intercourse with during an annual party called "The Drunken Barn Dance".
 Meanwhile, his friends Stan, Kyle and Kenny participate on "America's Stupidest Home Videos", after filming Cartman playing in his yard with plush toys.
Leopold "Butters" Stotch is a fictional character in the animated television series "South Park".
 He is voiced by series co-creator Matt Stone and loosely based on co-producer Eric Stough.
 He is a third- then fourth-grade student at the fictional South Park Elementary School.
 Butters is depicted as more cheerful, sweet, naive, optimistic, gullible, and passive compared to the show's other child characters and can become increasingly anxious, especially when faced with the likelihood of being punished, which is usually just being grounded, of which he is extremely terrified.
 As a result, he is often sheltered and unknowledgeable of some of the suggestive content his peers understand, and is also frequently the victim of abuse and manipulation by Eric Cartman.
 His name is a play on the confection butterscotch.
"Cartman's Mom Is Still a Dirty Slut" is the second episode in the second season of the American animated television series "South Park".
 The 15th episode of the series overall, it premiered on Comedy Central in the United States on April 22, 1998.
 The episode concludes the storyline of the season one finale "Cartman's Mom Is a Dirty Slut"; Mephesto is suddenly shot, just as he is about to reveal the identity of Cartman's father.
 The four boys and Chef rush him to Hell's Pass Hospital while the town of South Park experiences a massive blizzard.
