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]

“Everybody comes into our store looking for things to do, asking where do we go? We’ve had to be creative as a store because the last thing we want is to give people disappointing news,” Zehr said. The shop is offering more accessible options for backcountry skiing, like trails still in the park that can be reached from Colorado 7. But he said places that are typical destinations for his backcountry-ski renters, such as Hidden Valley, are “closed to 95 percent of the population because you have to be willing to hike out there.”
