Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4.5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a shallow sea, with a seabed composed of limestone and dolomite deposits many kilometers thick.[54] Pikes Peak granite formed during the late Precambrian eon, continuing well into the Paleozoic era, when mass quantities of molten rock flowed, amalgamated, and formed the continents about 1 billion–300 million years ago. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime and mud sediments were deposited in the vacated space. Eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin.[55]

I am convinced Chautauqua is Colorado’s best-kept secret and I’m amazed how few locals know about its charms.

Not to be forgotten are Pearl Street Mall’s restaurants, shops, people-watching and Pop Jet Fountain–they never fail to entertain.

From 9,000 ft (2,700 m) to 11,000 ft (3,400 m),[72] the montane forests give way to subalpine forests.[69] Forests of fir and Engelmann spruce cover the mountainsides in subalpine areas. Trees grow straight and tall in the lower subalpine forests, but become shorter and more deformed the nearer they are to the tree line.[72] At the tree line, seedlings may germinate on the lee side of rocks and grow only as high as the rock provides wind protection, with any further growth being more horizontal than vertical. The low growth of dense trees is called krummholz, which may become well-established and live for several hundred to a thousand years old.[72]

The history of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt and forage for food.[11][12] Ute and Arapaho people subsequently hunted and camped in the area.[13][14] In 1820, the Long Expedition, led by Stephen H. Long for whom Longs Peak was named, approached the Rockies via the Platte River.[15][16] Settlers began arriving in the mid-1800s,[17] displacing the Native Americans who mostly left the area voluntarily by 1860,[18] while others were removed to reservations by 1878.[14]
Zach Zehr, an avid backcountry adventurer, spends a lot of time in Rocky Mountain National Park, which is open but operating with a limited staff since Dec. 22, 2018, due to the federal government shutdown. Because of the shutdown, the roads aren’t being plowed so much of the park is not open to vehicle traffic. Fat bikes, however, work just fine. Zehr, who is also the manager at the Estes Park Mountain Shop, and some friends rode their fat bikes to the Bear Lake Trailhead and did a backcountry ski trip in the park on Jan. 6, 2019.

After facing near extinction last century, the bighorn sheep population is currently thriving: there are roughly 300–400 of these striking animals in the park.

Their visits generally occur between 9 a.m. and 3 p.m.

Frankenmuth in mid-Michigan is an interesting replica of a German town, where visitors make a customary stop at Zehnder's or The Bavarian Inn, known for their luscious fried chicken.

If you need a break from the action, you can visit the Pioneer Museum or a few of the local art galleries.


No matter the season, Crested Butte is one of the best weekend getaways in Colorado.

Split down the middle by the vast Rocky Mountains and jam-packed with national parks and wilderness areas, Colorado is an ideal travel destination for outdoor pursuits in every season. From skiing and whitewater rafting to hiking, biking and camping, outdoor activities are a way of life in the Centennial State. The state’s fun-loving culture attracts visitors looking for a laidback vacation too.

The park's climate is also affected by the Continental Divide, which runs northwest to southeast through the center of the park atop the high peaks. The Continental Divide creates two distinct climate patterns - one typical of the east side near Estes Park and the other associated with the Grand Lake area on the park's west side.[49] The west side of the park experiences more snow, less wind, and clear cold days during the winter months.[49]
