Merriam Peak, Mountain summit in White Cloud Mountains, Idaho, US

Merriam Peak is a mountain summit in the White Cloud Mountains that rises with steep rocky faces above Castle Lake in the Sawtooth National Recreation Area. The peak showcases the jagged granite formations typical of this remote range.

The peak takes its name from John H. Merriam, an advocate who worked to prevent molybdenum mining in the region. His efforts were key to keeping the landscape in its original state.

Merriam Peak lies within the White Clouds roadless area of the Sawtooth National Recreation Area, a designation that keeps the peak and its surroundings free of roads and mining. The name honors John H. Merriam, whose work helped protect the range from molybdenum extraction.

Climbing this peak demands scrambling ability and proper alpine gear, as the terrain is exposed and rocky throughout the ascent. Good weather and adequate preparation are essential before attempting the summit.

Merriam Peak sits in the watershed of Little Boulder Creek, a tributary of the East Fork of the Salmon River, and Castle Lake lies directly at its southern base, separating it from Castle Peak, the highest point of the White Cloud Mountains.
