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. Look for them at the aptly named Sheep Lakes from May through mid-August, when the bighorns descend to eat soil and obtain minerals not found in their high mountain habitat. Their visits generally occur between 9 a.m. and 3 p.m.
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] 
Surrounded on three sides by Rocky Mountain National Park, Grand Lake is aptly known as the “Western Gateway” to the Rockies. Because of its close proximity to the wilderness, it’s one of the best weekend getaways in Colorado for an itinerary full of adventure. Strap on your cross-country skis or rent a snowmobile to explore the area’s large network of trails no matter the weather. For indoor entertainment, head to the Rocky Mountain Repertory Theatre, which puts on professional shows loved by kids and parents alike.
Glacial geology in Rocky Mountain National Park can be seen from the mountain peaks to the valley floors. Ice is a powerful sculptor of this natural environment and large masses of moving ice are the most powerful tools. Telltale marks of giant glaciers can be seen all throughout the park. Streams and glaciations during the Quaternary period cut through the older sediment, creating mesa tops and alluvial plains, and revealing the present Rocky Mountains.[61] The glaciation removed as much as 5,000 feet (1,500 m) of sedimentary rocks from earlier inland sea deposits. This erosion exposed the basement rock of the Ancestral Rockies. Evidence of the uplifting and erosion can be found on the way to Rocky Mountain National Park in the hogbacks of the Front Range foothills.[60] Many sedimentary rocks from the Paleozoic and Mesozoic eras exist in the basins surrounding the park.[62]
Nicknamed the “Mile High City,” Denver is a haven for outdoor-lovers year-round, making it one of the best weekend getaways in Colorado for any type of travelers. Bring your camera along to capture views of urban and natural scenery alike—Larimer Square and the 16th Street Mall are two essential sightseeing destinations for first-timers, and Mount Elbert is always looming large in the background. The real Denver attraction, though, is the culture, which you can discover on a walk through the city’s distinct neighborhoods, on a Denver sightseeing tour, or a bike and brewery tour (it doesn’t get more Denver than that).
The sun made us lazy, and after following Brian as he made his way upstream I found a wider expanse of sand and gravel, promptly plopping down on a pair of flip flops I had brought in my backpack as a make-shift seat. After identifying the northern harrier hawk over my head, and the savannas sparrows and red-winged blackbirds perched precariously on reeds across the water, I took out my knitting project. I didn’t have to worry about losing Brian; in the valley I could see for miles in both directions.
