Mount Greylock is part of an {{convert|11|mi|km|adj=mid|-long}} massif called the "Greylock Range" near the Hoosic River, which hooks around the mountain on its eastern and northern footings. Various summits include Saddle Ball Mountain, along with Mount Fitch and others.

Standing about 2,000 feet (610 meters) above the local Hoosic Valley, Mount Greylock's summit is in Adams, Massachusetts. Other parts of the range extend into five neighboring towns. Sight lines of up to {{convert|72|miles|km|abbr=on}} are possible from Greylock.{{cite book|last1=Raymo|first1=Chet|last2=Raymo|first2=Maureen E.|year=1989|title=Written in Stone: A Geologic History of the Northeastern United States|location=Chester, Connecticut|publisher=Globe Pequot|isbn=978-0871063205}}{{cite book|title=Massachusetts Trail Guide|year=2004|location=Boston|publisher=Appalachian Mountain Club}}

The eastern slopes of Greylock are noted for the Thunderbolt ski trail (see below), landslide scars above the city of Adams and "Greylock Glen," a state-sponsored development plan. The western slopes include "The Hopper," a twin-pronged valley caused by erosion. https://www.nysga-online.org/wp-content/uploads/2019/06/NYSGA-2018-C4-Mount-Greylock-as-a-Cosmogenic-Nuclide-Dipstick-to-Determine-the-Timing-and-Rate-of-Southeastern-Laurentide-Ice-Sheet-Thinning.pdf {{Bare URL PDF|date=August 2024}} The mountain's north and southern reaches are noted for the presence of an auto road as well as hiking trails.

Mount Greylock is part of the much larger Taconic Allochthon, a structure that migrated to its present position from 25 miles to the east.Potter, D. B. (December 1, 1968) "Time and space relationships of the Taconic allochthon and autochthon [book review]" [https://www.ajsonline.org/content/266/10/995] The rocks moved via thrust faulting, a tectonic process by which older rock is thrust over and above younger rock.The Taconic Controversy: What Forces Make a Range?

More narrowly, the local massif is mostly "Greylock Schist," a term used by geologists starting in 1891 and much more recently, although the age of these rocks had been uncertain into the 1960s.see page 41-42 of ""Taconic Stratigraphic Names: Definitions and Synonymies" by E-an Zen, 1964 U Geological Survey Bulletin 1174 [https://pubs.usgs.gov/bul/1174/report.pdf] This Ordovician schist is about 1,000 to 2,000 feet thick on Greylock and "consists of muscovite (sericite), chlorite, and quartz schist." It lies above a formation called "Bellows Pipe Limestone."[https://ngmdb.usgs.gov/Geolex/UnitRefs/GreylockRefs_1897.html "National Geologic Map Database: Unit Greylock] This younger, underlying layer has been quarried on the lower slopes of the mountain.

The Laurentide Ice Sheet had covered the region up to a depth of one kilometer (or 3,281 feet). In melting, it formed Lake Bascom in the upper Hoosic Valley."Lake Bascom and the deglaciation of northwestern Massachusetts" Bierman, et al., 1986 [https://www.uvm.edu/cosmolab/papers/Bierman_1986_489.pdf]

The remains of lake beaches are evident at several places on the lowest slopes of Greylock.

Geologists used Surface Exposure Dating in 2018 to measure the rate of Pleistocene de-glaciation of the region. This method offered data in support of a more rapid melting rate in New England compared with earlier estimates.{{cite conference|last1=Halsted|first1=CT|last2=Shakun|first2=JD|last3=Davis|first3=PT|last4=Bierman|first4=PR|last5=Corbett|first5=LB|last6=Koester|first6=AJ|chapter=Mount Greylock as a cosmogenic nuclide dipstick to determine the timing and rate of southeastern Laurentide Ice Sheet thinning|editor1-last=Grove|editor1-first=Tim|editor2-last=Mango|editor2-first=Helen|title=Guidebook for field trips in New York and Vermont|conference=New England Intercollegiate Geological Conference, 110th Annual Meeting and New York State Geological Association, 90th Annual Meeting|date=October 12–14, 2018|location=Lake George, New York}}

"Mount Greylock" as the mountain's present name "probably originated with Williams College Professor Albert Hopkins" (1807–1872) or another local professor of the same era, according to one 1988 source.see chapter one, "Most Excellent Majesty: A History of Mount Greylock," Berkshire County Land Trust and Conservation Fund, 1988. [https://archive.org/details/mostexcellentmaj0000burn/page/n13/mode/2up?q=extent&view=theater] The peak's namesake, Gray Lock(c. 1670–1750) was an Abenaki tribal figure from near Westfield, Massachusetts, known for raiding English outposts near the Connecticut River{{cite book|title=The Western Abenakis of Vermont, 1600-1800: War, Migration, and the survival of an Indian people|url=https://archive.org/details/westernabenakiso0000call|url-access=registration|first=Colin G.|last=Calloway|publisher=University of Oklahoma Press|year=1990|isbn=9780806122748}} and not historically associated with the mountain.

The 18th century English may have called the peak "Grand Hoosuc," although Timothy Dwight IV referred to it as "Saddle Mountain" in his travel memoir concerning the late 18th century."Travels in New York and New England" Timothy Dwight 1821"

In the early 19th century it was called "Saddleback Mountain" because of its appearance seen from the south.{{cite web|url=http://www.berkshireweb.com/mohawktrail/mtgreylock.html|title=Mount Greylock State Reservation|publisher=The BerkshireWeb|access-date=March 6, 2008|url-status=dead|archive-url=https://web.archive.org/web/20150104012813/http://www.berkshireweb.com/mohawktrail/mtgreylock.html|archive-date=January 4, 2015}}

According to a 1838 journal entry (posthumously published 1868), Nathaniel Hawthorne overheard a local resident calling it "Graylock." Hawthorne added that Saddleback "is a more usual name for it." Yet elsewhere Hawthorne simply called it Graylock, attributing this name to the mountain's frequent appearance in winter frost.[https://www.gutenberg.org/files/8088/8088-h/8088-h.htm see July 27 entry, "American Notebooks, Vol I" Hawthorne]

Nonetheless, as of 1841, Edward Hitchcock's authoritative "Final Report" on state geology called the entire massif "Saddle Mountain" and "the highest point of the summit" according to Hitchcock was called "Graylock." .page 247, "Final Report on the Geology of Massachusetts>" 1841 Edward Hitchcock [https://archive.org/details/60741140R.nlm.nih.gov/page/n247/mode/2up?q=Graylock]

Three structures contribute to the 1930s "Mount Greylock Summit Historic District," which is part of the National Register of Historic Places as of 1998. These are the Bascom Lodge and the Thunderbolt Ski Shelter, both designed by Pittsfield architect, Joseph McArthur Vance, and the War Memorial Tower designed by Boston-based Maginnis & Walsh. Together, their cultural significance as period architecture was cited in the register

=== Bascom Lodge ===

File:Bascom Lodge atop Mount Greylock.JPG

Bascom Lodge was built between 1932 and 1938 using native materials of Greylock schist and red spruce{{cite web|url=http://www.bascomlodge.net|title=Bascom Lodge}} and characterized by the rustic design of period park structures. The Greylock Commission sought a more substantial shelter to replace an earlier summit house (built c.1902; destroyed by fire in 1929). The initial west wing was constructed in 1932 by Jules Emil Deloye Jr. The main-central and east wings were completed later 1935–38 by the Civilian Conservation Corps, supervised by Deloye. The lodge was named in honor of John Bascom, a Greylock Reservation Commissioner and local professor (d. 1911).{{cite web|url=https://www.waymarking.com/gallery/image.aspx?f=1&guid=27cb7d74-78db-4b1d-a17f-6a7ddbe57fef&gid=3|title=Sign about the CCC on Bascom Lodge|website=waymarking.com|access-date=June 9, 2023}}

For the winter of 1937–38, the Greylock Commission hired Harrison L. Lasuer to spend the season living in the lodge "to act as host to skiers and other Winter enthusiasts who scale the mountain."."Will Winter on Greylock in Mountain 'Penthouse' " November 13, 1937, New York Times, Page 41, The building was equipped for that winter with "steam heat, electricity and a telephone," according to a New York City newspaper. A ski race later that season attracted 7,000 spectators, mainly near the base of the mountain (see ref. below).

Today, Bascom Lodge is run (in warmer months only) by a service company under a concession-type lease from the state.{{cite web|url=http://www.mass.gov/eea/agencies/dcr/conservation/cultural-resources/historic-curatorship-program.html|title=Historic Curatorship Program|archive-url=https://web.archive.org/web/20130703063737/http://www.mass.gov/eea/agencies/dcr/conservation/cultural-resources/historic-curatorship-program.html|archive-date=July 3, 2013|url-status=dead|work=Energy and Environmental Affairs|publisher=Massachusetts Department of Conservation and Recreation}} Among other earlier arrangements, the Appalachian Mountain Club managed the lodge for 16 summers ending in 2000."Appalachian Mountain Club will no longer manage Bascom Lodge

File:Thunderbolt Skiers.jpg

The Thunderbolt Ski Shelter, also designed by Joseph McArthur Vance, was built in 1940 by the Civilian Conservation Corps (CCC) as a warming hut for skiers using the Thunderbolt Trail.Greylock State Reservation Commission Report for 1940

Like the nearby lodge, the shelter is rustic in design and built of local stone and wood beams; the interior has four wooden benches built into a large four-hearth fireplace in the center. It is several hundred feet north of the summit tower.

Although Bascomb Lodge reportedly employed a resident winter innkeeper in 1938 (see above citation), the 1940 introduction of this nearby shelter may have made a seasonal shut-down of the lodge less inconvenient during large-scale ski events of the era.

This trail was designed with help from numerous ski groups and cut by the CCC in 1934. Major competitive ski races were held on here almost annually from 1935 until 1948. Among the largest was a 1938 event attended by 7,000 spectators, who watched Fritz Dehmel of Nazi Germany set a course record of 2 minutes and 25 seconds."Tony Matt Annexes Mount Greylock Event" January 28, 1940, New York Times page 21"Dehmel Annexes Eastern Ski Race" February 7, 1938, NYT page 18 Famed U.S. skier Dick Durrance placed fifth in this race, which pre-dated the Thunderbolt shelter. Dehmel's record for the 1.4-mile course held until 1948. The trail is similar in steepness to the longer Sherburne Trail of Pinkham Notch, New Hampshire."Power Project" Thunderbolt Ski Trail" a slightly weak but useful source

Although area legislators and residents wanted local stone, the tower's granite facing was obtained in Quincy. The tower bears various inscriptions including, "they were faithful even unto death." One of the inscriptions inside the monument reads, "Of those immortal dead who live again in the minds made better by their presence", which is a line from a poem by George Eliot.

Melville is said to have taken part of his inspiration for Moby-Dick from the view of the mountain from his house Arrowhead in Pittsfield, since its snow-covered profile reminded him of a great white sperm whale's back breaking the ocean's surface.{{cite web|url=http://www.mobydick.org/hm.html|title=Herman Melville's Arrowhead|publisher=Berkshire Historical Society|access-date=March 9, 2008|url-status=dead|archive-url=https://web.archive.org/web/20000111064501/http://www.mobydick.org/hm.html|archive-date=January 11, 2000}} Melville dedicated his next novel, Pierre, to "Greylock's Most Excellent Majesty", calling the mountain "my own ... sovereign lord and king".

His account of this event in A Week on the Concord and Merrimack Rivers described his approach up what is today the Bellows Pipe Trail. Scholars contend that this Greylock experience transformed him, affirming his ability to do these excursions on his own, following his brother John's death; and served as a prelude to his experiment of rugged individualism at Walden Pond the following year in 1845.{{cite book|last1=Thoreau|first1=Henry David|last2=Howarth|first2=William L.|year=1983|title=Thoreau In The Mountains: Writings By Henry David Thoreau|location=New York|publisher=Farrar, Straus, Giroux|isbn=0-374-27643-9|url=https://archive.org/details/thoreauinmountai00thor}}

Timothy Dwight IV, a once-famed poet and preacher, and president of Yale College, along with Williams College President Ebenezer Fitch, climbed Greylock in 1799, probably over a rough route cut by a local farmer Jeremiah Wilbur. Dwight's travel memoir describes the mountain: "During a great part of the year, it is either embosomed or capped by clouds, and indicates to the surrounding inhabitants the changes of weather with not a little exactness."Dwight, Timothy IV (Reprinted 1969) Travels in New England and New York Ed.

Nine years later, it was replaced by a more substantial {{convert|60|ft|m|adj=on}} wooden tower, from which Donati's Comet was photographed in 1858.

The club frequently camped on the mountain and certain members later helped found the Appalachian Mountain Club and the American Alpine Club.{{cite news|last=Fanto|first=Clarence|date=August 7, 2007|url=http://www.cablemills.com/home/news/the_berkshire_eagle090707.html|title= Williamstown|newspaper=The Berkshire Eagle|location=Williamstown, MA|publisher=Media NewsGroup|access-date=March 6, 2008|archive-url=https://web.archive.org/web/20090105160416/http://www.cablemills.com/home/news/the_berkshire_eagle090707.html|archive-date=January 5, 2009|url-status=dead}}

By the late 19th century, clearcutting had stripped most of Greylock's forest. Along with this came forest fires and landslides. The Greylock Park Association (GPA) was formed in 1885 and shares were sold locally with plans to make money by attracting tourists.{{cite book|title=Acts and Resolves Passed by the General Court of Massachusetts 1885 |chapter=Chapter 166 |chapter-url=http://archives.lib.state.ma.us/actsResolves/1885/1885acts0166.pdf |publisher=The State Library of Massachusetts |access-date=July 20, 2012}}{{cite book|title=Greylock Reservation|first=John|last=Bascom|year=1907|pages=14–15|publisher=Press of the Sun}} The company purchased {{convert|400|acre|ha|abbr=on}} on the summit and made repairs to the Notch Road. The GPA charged a 25-cent toll for the carriage road and a 10-cent fee to ascend the iron observation tower (built 1889). Together, these fees are equivalent to ${{Formatprice|{{Inflation|US|0.35|1889|r=2}}}} in present-day dollars.{{inflation-fn|US}}

But 12 years later, with the GPA's business future imperiled by debt, local legislators proposed acquiring the company and forming Mount Greylock State Reservation. This was approved in 1898 along with plans to add to the original land (to ultimately total {{convert|12500|acre|ha|adj=on}}. The Berkshire County government was to maintain the reservation. Other early State Reservation properties were similarly operated by local county governments.{{cite web|url=http://www.mass.gov/eea/agencies/dcr/massparks/region-west/mount-greylock-state-reservation-history-and-culture-massachusetts-first-state-park.html |title=Massachusetts' First State Park |work=MassParks: Mount Greylock State Reservation |publisher=Executive Office of Energy and Environmental Affairs, Department of Conservation and Recreation |access-date=July 20, 2013}}

The first automobiles to the summit, via the Notch Road from the north, were a pair of steam-powered "Locomobiles' in 1902; a gasoline-powered car followed in 1904.see page 53, "Literary Luminaries of the Berkshires" 2015, Bernard A. Drew, History Press, Charleston SC In 1907, Berkshire County Commission opened a new road from the south to the summit,{{cite book |chapter-url=http://archives.lib.state.ma.us/actsResolves/1906/1906acts0419.pdf

The county subsequently attended to building hiking paths, and by 1913 had completed 17 trails. The Appalachian Trail route across the mountain was opened in 1929, and the entire Massachusetts section was mostly complete by 1931.

The Massachusetts (Veterans) War Memorial Tower on the summit was completed in 1932.{{cite book|chapter-url=http://archives.lib.state.ma.us/actsResolves/1930/1930acts0411.pdf |title=Acts and Resolves Passed by the General Court of Massachusetts 1930 |chapter=Chapter 411 |publisher=The State Library of Massachusetts |access-date=July 20, 2012}} During nine years ending in 1941 the Civilian Conservation Corps (CCC) worked on the mountain mostly through its 107th Company, MA camp SP-7.

CCC work included improvements to the road system (gravel surfaced), Adirondack lean-to shelters, the Thunderbolt Ski Shelter and its related trail, along with constructing much of Bascom Lodge.{{Cite news|last=Bradley|first=Matthew Timothy|date=February 17, 2013|title=Snowshoeing the Thunderbolt Ski Run|work=Snowshoe Magazine|url=https://www.snowshoemag.com/2013/02/25/snowshoeing-the-thunderbolt-ski-run/}}

Starting in 1954, the Greylock Tramway Authority was formed to build an aerial tramway on the mountain. After the authority announced plans for a ski resort in 1964, a local conservation group called the Mount Greylock Protective Association led a campaign to shift the Reservation to state management from Berkshire County. This succeeded in 1966 and helped to block the resort.{{cite news|url=https://theberkshireedge.com/barrington-selectboard-regional-school-district-need-equitable-agreement|title=Part I.

Mount Greylock has about 70 miles of hiking paths including an 11.5 mile section of the Appalachian National Scenic Trail. Primitive camping for backpackers is permitted at several sites. The staffed visitors' center in Lanesborough is open year-round (1.5 miles off Route 7).

The Greylock Glen, site of a former proposed tramway/ski/resort development from 1953 to 1977, is a {{convert|1063|acre|ha|adj=on|abbr=off}} park in Adams, adjoining Mount Greylock State Reservation. It was acquired by the state in 1985 for joint public-private development.Comm. of MA, Chap. 676, Acts of 1985
