Verplanck Colvin (1847–1920) named Mount Redfield for William C. Redfield (1789–1857), organizer and member of the first expedition to Mount Marcy in 1837, and the first to guess that Marcy was the highest peak in the Adirondacks, and therefore in New York.
Mount Redfield stands within the watershed of the Opalescent River, a tributary of the Hudson River, which in turn drains into New York Bay. The northeast and north sides of Mt. Redfield drain into Uphill Brook, thence into the Opalescent River. The west end of Redfield drains into Upper Twin Brook, thence into the Opalescent River. The south side of Redfield drains into Skylight Brook, thence into Dudley Brook and the Opalescent River.
