Reids Peak is an 11,724-foot mountain in Utah’s western Uinta Mountains, rising sharply above the Weber River headwaters and reached by the Mirror Lake Highway. Its name preserves early regional history: first recorded as Reeds Peak in 1875, it was officially standardized as Reids Peak in 1932 and honors William “Toopeechee” Reed, founder of Reed Trading Post in 1828, identified as the first permanent non-Indian residence and business in what became Utah. The peak also reflects a long geologic story, from Precambrian sediments and later uplift during the Laramide orogeny to Ice Age glaciation that carved the surrounding basin-dotted landscape visible from its summit.
