The Lost River Range is a high mountain range of the Rocky Mountains, located in Central Idaho, in the Northwestern United States. [1]
It runs southeast for approximately 75 miles (121 km) from the Salmon River near the community of Challis to the Snake River Valley near Arco. To the west are the valleys of the Salmon and the Big Lost Rivers, while to the east are the Little Lost River and Pashimeroi Valleys.
The range starts at the east bank of the Salmon River, at an elevation of about 5,000 feet (1,500 m). It quickly rises to Grouse Creek Mountain (11,085 ft; 3,379 m) and Dickey Peak (11,141 ft; 3,396 m), and then descends to Double Springs Pass, location of one of just two roads to cross the range. Nearby is an interpretive site explaining the effects of the magnitude 6.9 Borah Peak earthquake that hit the range on October 28, 1983. The Big Lost River Valley fell and the Lost River Range rose, leaving a fault scarp of up to 14 ft (4.3 m) along the base of the mountains.
The range then rises into its high central section, which includes many of the state's highest peaks. Borah Peak, the highest, climbs to 12,662 ft (3,859 m). Further south are Mount Idaho (12,065 ft; 3,677 m), Leatherman Peak (12,228 ft; 3,727 m), Mount Church (over 12,200 ft; 3,700 m), Mount Breitenbach (12,140 ft; 3,700 m), and Lost River Mountain (12,078 ft; 3,681 m). To the east of this section of the range lie the remote canyons of the Upper Pashimeroi Valley, including scenic Merriam Lake.
The range then descends to Pass Creek Summit, the second road to cross its crest. It continues to King Mountain (10,612 ft; 3,235 m), a favorite site for hang gliders. Finally it descends sharply to the Snake River Valley near the community of Arco, at an elevation of 5,300 ft (1,600 m).
The San Gabriel Mountains are a mountain range located in northern Los Angeles County and western San Bernardino County, California, United States.

The range lies in, and is surrounded by, the Angeles and San Bernardino National Forests, with the San Andreas Fault as its northern border.
The Bitterroot Range is a mountain range and a subrange of the Rocky Mountains that runs along the border of Montana and Idaho in the northwestern United States. The range spans an area of 24,223 square miles (62,740 km2) and is named after the bitterroot, a small pink flower that is the state flower of Montana.
Borah Peak, also known as Mount Borah or Beauty Peak, is the highest mountain in the U.S. state of Idaho and one of the most prominent peaks in the contiguous United States. It is located in the central section of the Lost River Range, within the Challis National Forest in eastern Custer County. On February 11, 2021, the USGS officially recognized Mt. Borah as Idaho's only active glacier.

Much of the mountain range is within the Sawtooth Wilderness, part of the Sawtooth National Recreation Area and Sawtooth National Forest.

The Centennial Mountains are the southernmost sub-range of the Bitterroot Range in the U.S. states of Idaho and Montana. The Centennial Mountains include the Western and Eastern Centennial Mountains. The range extends east from Monida Pass along the Continental Divide to Henrys Fork 48 km (30 mi) NNW of Ashton, Idaho; bounded on the west by Beaver Creek, on the north by Centennial Valley and Henrys Lake Mountains, on the east by Henrys Lake Flat, and on the south by Shotgun Valley and the Snake River Plain. The highest peak in the range is Mount Jefferson.
