A mountain pass is a navigable route through a mountain range or over a ridge. Since mountain ranges can present formidable barriers to travel, passes have played a key role in trade, war, and both human and animal migration throughout history. At lower elevations it may be called a hill pass. A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind.
Torreys Peak is a mountain in the Front Range region of the Rocky Mountains in Colorado. It is one of 53 fourteeners in Colorado. Its nearest major city is Denver. Torreys Peak is located along the Continental Divide, as well as the division between Clear Creek County and Summit County. In the Arapaho language Torrey's Peak and the adjacent Gray's Peak are named, Heeniiyoowuu or "Ant Hills".

Miller Peak, at 9,470 feet (2,886 m), is the second-highest mountain in Cochise County, Arizona. Located approximately 10 miles south of Sierra Vista, Arizona, it is the highest mountain in the Huachuca mountain range and a popular local hiking destination. The Miller Peak Wilderness encompasses 20,190 acres and is managed by the Coronado National Forest. This is also the most southerly peak and land area to rise above 9,000 feet in the continental United States. The area was affected by the 2011 Monument fire and most of the pine trees seen in older photographs were burned and destroyed. Scrub oak are beginning to replace the areas that were previously covered by pine.
East Spanish Peak is a prominent mountain summit that is the lower of the two Spanish Peaks in the Rocky Mountains of North America. The 12,688-foot (3,867 m) peak is located in the Spanish Peaks Wilderness of San Isabel National Forest, 9.3 miles (14.9 km) southeast by south of the Town of La Veta, Colorado, United States, on the drainage divide between Huerfano and Las Animas counties. The Spanish Peaks are two large igneous stocks which form an eastern outlier of the Culebra Range, a subrange of the Sangre de Cristo Mountains. East Spanish Peak is higher than any point in the United States east of its longitude; it is also the easternmost point in the United States over 12,000 feet (3,700 m), 11,000 feet (3,400 m), and 10,000 feet (3,000 m) feet above sea level.
The Sør Rondane Mountains are a group of mountains about 100 miles (160 km) long with main peaks rising to 3400 m, between the Queen Fabiola Mountains and Wohlthat Mountains in Queen Maud Land. They were discovered and photographed from the air by members of the Lars Christensen Expedition (LCE) on February 6, 1937, and named after Rondane, a mountain massif in southern Norway. The mountains and their constituent features were mapped in greater detail and named in 1957 by Norwegian cartographers working with air photos taken by U.S. Navy Operation Highjump, 1946–47.
Thompson Peak is the highest peak in the Sawtooth Range of Idaho. Its 10,751 ft (3,277 m) summit is located within Custer County, although some of the lower portion of the mountain is in Boise County. Thompson Peak is also located within the Sawtooth Wilderness portion of the Sawtooth National Recreation Area, a unit of Sawtooth National Forest. The town of Stanley, Idaho is about 6 miles (9.7 km) northeast of Thompson Peak.

The saddle between two hills or mountains is the region surrounding the saddle point, the lowest point on the line tracing the drainage divide connecting the peaks. When, and if, the saddle is navigable, even if only on foot, the saddle of a (optimal) pass between the two massifs, is the area generally found around the lowest route on which one could pass between the two summits, which includes that point which is a mathematically when graphed a relative high along one axis, and a relative low in the perpendicular axis, simultaneously; that point being by definition the col of the saddle.
