Thompson and Meserve's Purchase is notable for encompassing the northern slope of Mount Washington, including a large portion of the Mount Washington Auto Road and Cog Railway.
Thompson and Meserve's Purchase was sold by Commissioner Willey to Samuel W. Thompson of Conway and George P. Meserve of Jackson, New Hampshire, in 1835 for $500.[3]
The purchase is situated just north of the summit of Mount Washington and includes much of the northern Presidential Range, including Mount Adams, the second highest mountain in New Hampshire at 5774feet, and Mount Jefferson, the third highest peak at 5712feet. The highest point in the purchase is 6000feet above sea level on the slope of Chandler Ridge, just north of the summit of Mount Washington. To the east of the Presidential peaks lies the Great Gulf, a deep glacial cirque. The Appalachian Trail crosses the purchase, close to the crest of the Presidential Range.
