This area consists of 11 Counties: Bannock, Bear Lake, Bingham, Bonneville, Caribou, Cassia, Franklin, Madison, Oneida, Teton, and Twin Falls Counties.
Most of the peaks in this region are shorter than the Central Idaho mountains with only two, Cache Peak (10,339 ft.) and Mount Baird (10,025 ft.), topping 10,000 ft. The majority of the highest peaks in Southeastern Idaho reach above 9000 ft. but don't quite make the 10,000 ft. mark. Cache Peak sits outside the main concentraion of ranges in Southeastern Idaho in the Albion Range. The Albion Range is the farthest west of the mountains in this area with most of the ranges concentrated near the Wyoming border. Mt. Baird is in the Snake River Range which straddles the Idaho/Wyoming border just north of Palisades Reservoir and the Snake River.
There are also a great deal of low, north-south running ridges throughout the region. Many of them are called ranges but they are quite small and can be included as sub ranges.
RangesThere are 11 major ranges in this area and many sub ranges.
Oxford Peak (9282 ft.)which sits on the Oneida/Franklin County line. It is also the mountain in the range and one of Idaho's most prominant peaks.
Sherman Peak (9,682 ft.) in Bear Lake County. It also contains the Franklin County High Point (Point 9,484 ft.).
Blackfoot BM (7,550 ft.) but is the county high point for Bingham County. Most of the land is privately owned.
This range runs for about 30 miles between the Portneuf and Blackfoot Rivers. It is only a low series of ridges and has no prominant peaks. It does reach over 7,000 feet though.
This is considered to be the smallest mountain range in idaho. It is only 7 miles long and 3 miles wide and runs from Chesterfield south to Soda Springs. The highest point is at 6, 851 ft.
Black Pine Mountains
The Black Pine range is located in the extreme southeast corner of Cassia county and according to Tom Lopez in Idaho: A Climbing Guide, is "the most distinctly defined mountain range in Idaho. It is surrounded by wide valleys, and rises steeply on all sides." It runs in a north-south direction for 17 miles and offers spectacular views of the Great Salt Lake in Utah. The range is quite remote and is seldom visited by hikers and climbers. The highest mountain in the range is Black Peak at 9,395 ft. Black Pine peak is only 10 feet shorter at 9,385 and is a little more than a mile away from Black Peak. There are no other peaks above 9,000 ft. in this range but the other major peaks are all at about 8,000 ft.
Gray's Lake National Wildlife Refuge. Caribou Peak is the highest mountain here at 9,803 ft. It also has a prominance of 3,000+ ft. and rises abruptly from the marshes of Gray's Lake. In the late 19th and early 20th centuries Caribou Mountain was the site of a large gold rush that lasted 20 years and produced more than $50 million in placer gold! A large mining town called Caribou City was established at the foot of the mountain in 1897 and during its heyday boasted more than 1,500 residents. That was almost as much as Pocatello and Eagle Rock (Idaho Falls) at that time! By the 1930's it was completely abandoned and remains a ghost town to this day.
The name Caribou is often associated with this area and it can be a little misleading as Caribou do not live here. In 1870, a man by the name of Jesse Fairchild discovered gold near Caribou Mountain with two fellow miners. He was given the nickmname of "Cariboo" Jack and it was later corrupted into "Caribou". It is after "Cariboo" Jack that Caribou Mountain, the Caribou Range, and Caribou County are named.
There is one roadless area in the range.
Deep Creek Mountains
Deep Creek Peak at 8,748 ft. and Bannock Peak at 8,263 ft. the range is mostly managed by the BLM except for the northern portion, which is controlled by the Fort Hall Indian Reservation. Bannock Peak lies on resevation lands.
Meade Peak (9,959 ft.). Meade Peak is also the county highpoint for both Bear Lake and Caribou Counties as is sits on the county line.
This is the northernmost subrange of the Peale Mountains. It is about 10 miles long and is situated south of Gray's Lake. The highest point in this range is 8,320 ft. Lanes Butte.
At only 7 miles long this is the smallest of the subranges. It is east of Blackfoot Reservoir. The highest point is unnamed and sits at 7,800 ft.
This subrange forms the Eastern edge of the Peale Mountains. It is about 25 miles long and roughly follows the Idaho/Wyoming border. The highest point is Draney Peak at 9,131 ft.
The Preuss Range is the southernmost, and highest, of the subranges in the Peale Mountains. It is about 25 miles long and about 12 miles wide. The highest point in the range is Meade Peak at 9,959 ft.
The Snake River Range also contains a sub-range Called the Big Hole Mountains that extends north into Teton County.
There is one roadless area in the Snake River Range.
The Sublett Mountains are named after the trapper William Sublette who was in this area of Idaho during the 1830's. This mountain range extends from the Snake River in the North to the Utah border near Snowville in the South. It is not a very high mountain range and the highest peak is an unnamed summit at 7,492 feet. The highest named summit is Cedar Creek Peak at 7,464 feet. It separates the Raft River Valley from the Rockland Valley to the East.
ClimateThe majority of Southeastern Idaho is characterized by ancient lava flows covered with sagebrush. The mountains, however, are thikly covered in pine, fir, and aspen. Many of the mountains are just low ridges or hills running into the Snake River Plain with trees thickly covering their north and eastern sides. South and west facing slopes are generally bare of trees. So if you are looking to the north in the majority of this region it will look quite dry and barren. It you are looking to the south though the lanscape will be one of mountains and forest. Generally the farther you go north and east the more trees there will be.
This area can see extremes in temperature during the year. In the summer it can be miserably hot with temperatures approaching 100 degrees. It can also be bitterly cold in the winter, reaching below zero quite often. Southeast Idaho can also receive quite a bit of snow during some winters.[img:394987:aligncenter:medium:The Bear Lake Valley]
