At 4360 feet, Mount Marshall is the twenty-fifth highest peak in the Adirondacks.  It is southern most peak in the MacIntyre Mountain Range.  This tree covered summit is not as popular as the other peaks in the MacIntyre Range (Algonquin, Wright and Iroquois).  Most who climb this peak are those attempting to join the ADK 46er club.

There is no maintained trail to the summit, however there is a worn herd path.  The most popular route is to start from the Upper Works trailhead and take the Calamity Brook Trail past Flowed Lands.  The herd path begins just north of the bridge over Herbert Brook.  Although the summit is tree covered, there are a few good views.  This is a 6+ mile one way hike to the summit.
