Discovering Fall Foliage: Mountains

America’s Mountain region refers to the U.S. states that encompass the Rocky Mountains—Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah and Wyoming. These states have the highest mean elevations in the country, and with the exception of Nevada, all observe the Mountain Time Zone.

The climate in the mountain states is semi-arid to arid, with some alpine climate areas in the mountains. Because the elevation varies so much in this region, some parts receive significant amounts of rain and snow, while others receive hardly any rain and no snow. Temperatures also range significantly from state to state. For example, fall in Nevada sees temperatures from 75 to 102 degrees Fahrenheit, and in Idaho, fall temperatures are generally between 55 to 70 degrees. Due to the temperature differences, the peak of fall colors also varies state to state, and even within a state. However, mid-October is generally the peak.

One of the most unique trees found in the Mountains is the quaking aspen, or golden aspen. Each fall, these trees cover the mountains with stunning shades of gold and yellow. Interestingly, the quaking aspen has the widest natural range of any tree in North America and is considered one of the largest living organisms on earth!

If you’re planning a trip to the Mountains this fall, check out Rocky Mountain National Park. This time of year is perfect for viewing wildlife and it tends to be less crowded. September and October are usually mild and warm during the day; however, mornings and evenings can be chilly. So, make sure to dress in layers if you decide to hike through the region’s state and national parks, take a train ride through the mountainside, or check out any of the annual fall festivals!
