The elevation of a location tells us how high it is in relation to sea level. In the case of Jackson Hole, since this location is a valley with changing elevations from one point to the next, we have to look at the mean elevation, calculated by measuring the elevation in various points and finding an average. The average elevation in Jackson Hole is 6,500 feet (2,000 m) above sea level. In the town of Jackson, the elevation is 6,237 feet (1,901 m), so the elevation of Jackson is slightly lower than the average for the valley. This is due to the fact that Jackson is situated at the southern end of Jackson Hole, which has a lower elevation than the northern section.
The elevation of Jackson Hole is relatively high, with most towns and cities around the United States being situated at elevations of 500 feet (152 m) or less in general due to their coastal locations. In the case of Wyoming, this is actually one of the highest states on average in terms of elevation. The mean elevation in Wyoming is 6,700 feet (2,040 m), only 100 feet lower than the highest state of all, Colorado. So, when compared to the state average, we can see that the elevation of Jackson Hole is just slightly lower.
The highest point in Wyoming is Gannett Peak, a mountain in the Wind River Range, which has an elevation of 13,809 feet, while the lowest point in the state is the Belle Fourche River on the border between Wyoming and South Dakota, which has an elevation of 3,101 feet (945 m). The lowest point of Wyoming is still relatively high, with the entire state being at least several thousand feet above sea level. Major cities in Wyoming include the state capital of Cheyenne, which has an elevation of 6,062 feet (1,848 m), Casper, which has an elevation of 5,150 feet (1,560 m), Laramie, which has a population of 7,165 feet (2,184 m), and Gillette, which has an elevation of 4,554 feet (1,388 m).
