Question: "The Forest" follows a young woman who travels to a forest on the northwestern flank of what mountain?
Context: Larch Mountain, elevation 3480 ft , is the highest free-standing peak in Clark County, Washington.  (The andesite plugs Pyramid Rock and Sturgeon Rock are higher but are outcroppings on ridges of Silver Star Mountain.)  It is laced by a network of gravel roads as part of the Yacolt Burn State Forest.  The eastern flank of the mountain was scorched by a gigantic forest fire in September 1902 and subsequently experienced a massive rockslide that rendered that side mostly unvegetated.  The southern section of the mountain is part of the Jones Creek Off-Road Vehicle recreation area.  From the picnic area at the top, the view is west toward the Vancouver, Washington area and east to Silver Star.  A minimum security prison/work camp is situated nearby, whose inmates construct fire roads, fire trails, maintain campgrounds and help fight fires in the area. The Forest is a 2016 American supernatural horror film directed by Jason Zada and written by Ben Ketai, Nick Antosca, and Sarah Cornwell.  Starring Natalie Dormer and Taylor Kinney, it follows a young woman who travels to Aokigahara (the suicide forest) to find her sister. The Slave Market is a painting of about 1882 by the 19th century French artist Gustave Boulanger, who specialized in classical and Orientalist genre scenes.  It depicts an Ancient Roman slave auction.  It shows the marketing of seven young people, ranging in age from children to young adults, as slaves.  Both male slaves, as well as three of the female slaves, bear a similarity in appearance perhaps suggesting that they are members of a family forced into slavery by economic conditions.  All are wearing tags to indicate their availability as slaves.  The youngest boy is completely naked, while the young man next to him is wearing a loincloth.  The young woman sitting next to them is topless, wearing only a skirt, but she is covering her breasts with her legs.  The standing African woman is also topless, wearing a white loincloth, and she is covering her breasts with her hands.  The taller, standing, young woman is wearing a translucent garment which clearly shows her breasts and pubic hair—she is trying to shield her eyes, perhaps because her potential buyers include former friends and neighbors, who are probably seeing her nude for the first time.  The adolescent girl next to her is also topless and barefoot, wearing a skirt.  The young woman sitting next to them is wearing a loose garment which leaves both her breasts and her genitals exposed.  The auctioneer eats his lunch with a very casual attitude. Huntingdon County, is an historical county in southwestern Quebec, Canada.  It is named after the town and county of the same name (Huntingdon, Huntingdonshire) in east central England.  It is situated in the Montreal South Shore region of Montérégie, one of the roughly 12 regions of Quebec.  The county is bound entirely on its south by the Canada–US border (45° N for 88.75 km from 73°32′ W to 74°40′ W), along its northwestern flank by Lake St-Francis (Lac St-François) of the Saint Lawrence River to its most northern point on the river at 45°13′ N and 74°13′ W, to the east by Saint-Jean County, with its easternmost point at 45°5.5' N and 73°31′ W (this point forms the junction of the borders of Châteauguay County, Napierville County and Saint-Jean County) and to the north from east to west by Napierville County, Châteauguay County, and Beauharnois County.  On the other side of the Saint Lawrence River is Soulanges County, Quebec, the Township of Lancaster and the Township of Charlottenburgh in Glengarry County, Ontario, and the Township of Cornwall in Stormont County, Ontario. The Wutach Gorge (German: "Wutachschlucht" ) is a narrow, steep-sided valley in southern Germany through in the upper reaches of the River Wutach with three gorge-like sections, the lowest of which is also called the "Wutachflühen".  The gorge cuts through the southern part of the Baar region from the eastern side of the High Black Forest heading eastwards to the "Trauf" the steep, northwestern flank of the Swabian Jura, which transitions to the Randen mountains here. Midway High Lakes Area, also known as High Lakes Area is a United States Forest Service designated area located in Washington’s Cascade Mountains.  It lies on a high plateau on Mount Adams' northwestern flank.  It is between the Goat Rocks on the north and Mount Hood to the south and contains Takhlakh Lake along with several other lakes.  The area offers five scenic high elevation lakes all within a seven mile radius.  It is administered by the Gifford Pinchot National Forest.  While even the most visited areas at Mount Adams pale in comparison to nearby St. Helens or Rainier, it is by its own standards one of the most popular recreational areas around Mount Adams.  Some of the lakes offers photogenic views of Mount Adams from across the lake. Aokigahara (青木ヶ原 ) , also known as the Suicide Forest or Sea of Trees (樹海 , Jukai ) , is a forest on the northwestern flank of Japan's Mount Fuji thriving on 30 square kilometers (12 square miles) of hardened lava laid down by the last major eruption of Mount Fuji in 864 CE.  The western edge of Aokigahara, where there are several caves filled with ice, is a popular destination for tourists and school trips.  Parts of Aokigahara are very dense, and the porous lava absorbs sound, helping to provide visitors with a sense of solitude. Flett Glacier refers to two glaciers on the northwestern flank of Mount Rainier in the U.S. state of Washington.  The glaciers lie on a subsidiary peak of Rainier, the 8364 ft Observation Rock.  There are two sections of glacial ice, an eastern lobe at about 7600 ft to 7300 ft in elevation, a smaller western lobe at about 7200 ft in elevation.  Meltwater from the glacier flows into the Puyallup River. Māhukona is a submerged shield volcano on the northwestern flank of the Island of Hawaiʻ i.  A drowned coral reef at about 3,770 feet (-1,150 m) below sea level and a major break in slope at about 4,400 feet (-1,340 m) below sea level represent old shorelines.  The summit of the shield volcano was once 800 feet (250 m) above sea level.  It has now subsided below sea level.  A roughly circular caldera marks the summit of Māhukona.  A prominent rift zone extends to the west.  A second rift zone probably extended to the east but has been buried by younger volcanoes.  The main shield-building stage of volcanism ended about 470,000 years ago.  The summit of the shield volcano subsided below sea level between 435,000 and 365,000 years ago. The Bichtenberg is a 400-metre-high hill in the western Wasgau, a region on the Franco-German border that includes the southern part of the Palatine Forest and the northern part of the Vosges.  Its northwestern flank is in the parish of Lemberg, its southwestern flank in the parish of Dahn.  To the north is the Lemberg hamlet of Salzwoog.  Three kilometres west lies the Salzwoog Devil's Table.
