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]
Victorian elegance sets the standard for southwestern hospitality at the General Palmer Hotel, located in the heart of Durango, Colorado. Opened in 1898, it was named for one of this town’s founding fathers and remains as the only historical Four Diamond in southwestern Colorado.

The Experience: While news just broke that the old-timey train that travels along the mountainside through Pikes Peak will be closed for repairs for the rest of 2018, the nearby town of Manitou Springs should definitely stay on your bucket list. This resort town, located outside of Colorado Springs, is a true gem, complete with 1000-year-old Anasazi (the Ancestral Puebloans) cliff-dwelling ruins in the Mesa Verde National Park and a Victorian-era castle museum and tea room. Stay at the quaint Holden House bed and breakfast.
Crested Butte may be off the beaten path, but it’s worth the trip as one of the most stunning mountain towns in all of Colorado. The atmosphere is one that combines the charms of a historic mining town with hippy flair. Set at the base of the Rockies, it’s world-renowned for skiing, but in the warmer months, it becomes a top hiking and mountain biking destination, as well as drawing countless visitors for the chance to take once-in-a-lifetime whitewater rafting adventures through the Taylor Canyon. A true mecca for mountain bikers, there are hundreds of miles of trails linked together to create an endless day of touring from Gothic to Mt. Crested Butte, Irwin to Gunnison, or even from Crested Butte all the way to Aspen. If you don’t have a bike, stop by Big Al’s Bicycle Heaven and rent one for the day or for the length of your stay. In addition to riding the trails, you can ride around town and check out all the historic buildings and funky alleyways.
Located on Main Street of the charming historic mining town of Frisco, Colorado, the Frisco Lodge Bed and Breakfast has been greeting guests with comfort, luxury, and old-world hospitality since 1885.
