The eastern half of the range splits into two parallel ridges, the northern of which is known as the Enchantment Peaks.

[1] Collectively, the basin and the encircling eastern peaks of the Stuart Range make up The Enchantments, a well-known backpacking destination.

Two plutonic masses are separated by a thin screen of Chiwaukum Schist and rocks of the Ingalls Complex.

Continuing uplift and erosion has exposed the underlying granite batholith, making for one of the more spectacular mountain ranges in Washington.
