Street Mountain stands at 4,166 feet in the Adirondack High Peaks of North Elba, Essex County, New York, ranking 31st among the ADK 46ers. The peak was named in 1872 by surveyor Verplanck Colvin after Alfred Billings Street, the New York State Librarian, and its first recorded ascent came on June 27, 1921, by conservationist brothers Bob Marshall and George Marshall along with their guide Herbert Clark. Nye Mountain sits along the same ridge and the two summits are almost always combined into a single outing.
The approach departs Adirondak Loj at Heart Lake. A short way along the Indian Pass Trail, an unmarked but well-established herd path continues straight where the marked trail turns toward Mount Jo. This herd path crosses Indian Brook and climbs the slope of Nye Mountain before continuing to Street's summit, roughly 4 miles from the Loj. The full round trip is approximately 8.8 miles with around 1,900 feet of gain. Because there is no maintained or marked trail, map and compass or GPS navigation are essential; the herd path can be indistinct and the terrain featureless in places.
The wooded summit opens to pleasant outlooks on the approach ridge with views across the surrounding High Peaks. The trailless character keeps this pairing quieter than the busier marked routes out of the Loj. Snow and ice on the north-facing slopes can persist well into May, so microspikes and gaiters are often useful in early spring.
