Coalburg is an unincorporated community in Jefferson County, Alabama, United States.
 Coalburg was home to coal mines first developed by John T. Milner, who sold them in May 1883 to the Georgia Pacific Railway.
 Edward Magruder Tutwiler became the superintendent of the mines.
 Sloss-Sheffield Iron and Steel Company operated coke ovens at Coalburg during this time.
 At its peak, the Coalburg mines produced four thousand tons of coal per day.
 Overall, the Coalburg mines produced over 186,000 tons of coal.
 Sloss used convict labor to work in the Coalburg mines, with 320 men working in 1889.
 As the mines grew, the number of convicts used to work in the mines increased.
 The coal mined at and coke produced in Coalburg was sent to Sloss Furnaces in Birmingham to be turned into pig iron.
Altamont is an unincorporated community in Garrett County, Maryland, United States.
 Altamont sits on the Eastern Continental Divide between the watershed of Crabtree Creek, which flows into the Savage River and eventually into the Atlantic Ocean, and the watershed of the Little Youghiogheny River, which flows into the Youghiogheny River and eventually into the Gulf of Mexico.
 Altamont is notable as the spot at which the B&O Railroad crossed the divide.
 Today, that same spot is crossed by CSX's Mountain Subdivision.
 Altamont also features the intersection of Maryland Route 135 (MD 135) and MD 495.
Red Mountain is a long ridge running southwest-northeast and dividing Jones Valley from Shades Valley south of Birmingham, Alabama.
 It is part of the Ridge-and-Valley region of the Appalachian mountains.
 The Red Mountain Formation of hard Silurian rock strata lies exposed in several long crests, and was named "Red Mountain" because of the rust-stained rock faces and prominent seams of red hematite iron ore.
 The mountain was the site of the Sloss Mines, which supplied ore to Birmingham's iron furnaces.
 The best displays of the mountain's geological strata occur at the Twentieth Street cut near the Vulcan statue and at the U.S. Route 31 highway cut leading into the suburb of Homewood.
 Most of Birmingham's television and radio stations have their transmission towers located on Red Mountain.
 Red Mountain is also home to the newly created Red Mountain Park, one of the nation's largest urban parks at 1500 acre , making it larger than even New York City's Central Park.
MINES ParisTech (officially École nationale supérieure des mines de Paris (MINES ParisTech), also known as École des mines de Paris, ENSMP, Mines Paris or simply les Mines), created in 1783 by King Louis XVI, is a French engineer school and a constituent college of PSL Research University.
Campbell Field, officially Marv Kay Stadium at Harry D. Campbell Field, is an American college football stadium located in Golden, Colorado.
 The stadium serves as the home field of the Colorado Mines Orediggers football team representing the Colorado School of Mines.
 Campbell Field is one of the oldest football fields in existence, the oldest west of the Mississippi River and the oldest in NCAA Division II.
 Originally it was a dirt surface all-purpose athletic field in exactly its current configuration, built within a clay pit, a fitting mined-out home for the Orediggers.
 Its first athletic contest, held on May 20, 1893, was the first annual Colorado Inter-Collegiate Athletic Association Field Day, featuring many athletic contests between the University of Colorado, Colorado A&M, Colorado School of Mines, and the University of Denver, in which Mines claimed the most medals.
 Its first football game took place on October 7, 1893, a 6-0 Mines victory over the University of Denver.
 It has been home to the football Orediggers through all but the first five seasons of their existence (their previous home were the now-destroyed grounds at the southeast corner of 19th and Illinois streets in Golden), and has been renovated several times throughout its existence.
 The field was originally called Athletic Park, renamed Brooks Field after Mines trustee and benefactor Ralph D. Brooks in 1922, and renamed Campbell Field after 1939 undefeated team member and benefactor Harry D. Campbell in 2010.
 Campbell Field is the oldest football field in the west, the oldest in NCAA Division II football and the 5th oldest college football field in the nation.
The Altamont School, located in Birmingham, Alabama atop Red Mountain, is a college preparatory day school with coeducational enrollment of grades 5–12.
 The Altamont School enrolls approximately 365 students.
 Most of the students live in Birmingham and the surrounding communities.
The Sloss Mines are a group of mines in southwestern Jefferson County, Alabama.
 They were established by the Sloss Iron and Steel Company and its successor, the Sloss-Sheffield Iron and Steel Company, on the southern end of Red Mountain.
 The Sloss Iron and Steel Company itself was founded by James Sloss in 1881 as the Sloss Furnace Company.
 The Sloss Mines produced iron ore from 1882 until the 1960s.
 The ore that these mines produced were essential to the production of iron at the Sloss Furnaces, consequently making them an important element in the formation of adjacent Birmingham and Bessemer as cities.
Altamont (formerly The Summit and Alta Monte) is an unincorporated community in Alameda County, California.
 It is located 7.5 mi northeast of Livermore, at an elevation of 741 ft in the Altamont Pass.

Loveless Academic Magnet Program (LAMP) is a magnet high school located in Montgomery, Alabama.
 It has a student body of around 490.
 LAMP was formerly housed at Sidney Lanier High School, but moved into the former site of Loveless Elementary in 1999.
 A 9th grade class was added in 2001.
 In 2008, it was named #18 on U.S. News & World Report's Gold Medal List and #56 in Newsweek's list of the top 1000 high schools in the United States.
 In 2011, Newsweek ranked LAMP as the number 13 best high school in the United States.
 In 2013, LAMP was named the #1 high magnet high school in the nation, #1 in the state, and #7 overall by U.S. News & World Report.
 LAMP has accrued extensive scholastic acclaim, particularly in its ability to produce National Merit Scholars.
 Acceptance into LAMP is based upon academic records indicating demonstrated ability to complete higher-level academic courses and maintain disciplined study and work habits.
 However, due to Federal mandates, LAMP has changed its acceptance requirements into a lottery based acceptance.
 LAMP has had state tournament appearances as of 2007.
 In 2008-2009, the Tigers baseball team went to the state championship against Hokes Bluff and lost in two games to be the state runners-up.
 Also in that year, the basketball and soccer teams won the area but were defeated by Dallas County and Altamont respectively, resulting in both placing third in the state.
 Boys basketball also advanced past the area championship in 2017, but lost to Bullock County in the region playoffs.
 In 2014, LAMP was recognized as an International Baccalaureate World School and began its IB program in the fall of that year.
 May 2016 saw the first IB class graduate with great success both inside and outside the classroom.
 Unfortunately, the decision was made at the end of July, 2017 to not renew the IB program; therefore, the last IB class will graduate in May, 2019.
 On September 17, 2014, Montgomery Public Schools announced that LAMP would receive a new school site due to several technical problems with the building that officials deemed unsafe.
 MPS also said that until 2016, the students would temporarily be moved into a previously closed school known as Houston Hills.
 Due to the inevitable delays in construction the date for the school to move was postponed, but the new site of the school is at the Montgomery Mall's old site, alongside Montgomery's Technology school.
 The area has been reconstructed as OneCenter.
