The riparian ecosystem runs through the montane, subalpine, and alpine tundra zones and creates a foundation for life, especially for species that thrive next to streams, rivers, and lakes.[74] The headwaters of the Colorado River, which provides water to many of the southwestern states, are located on the west side of the park. The Fall River, Cache la Poudre River and Big Thompson Rivers are located on the east side of the park. Just like the other ecosystems in the park, the riparian zone is affected by the climatic variables of temperature, precipitation, and elevation. Generally, riparian zones in valleys will have cooler temperatures than communities located on slopes and ridge tops. Depending on elevation, a riparian zone may have more or less precipitation than other riparian zones in the park, with the difference creating a shift in the types of plants and animals found in a specific zone.[75]
A classic Colorado city just up the road from Denver, Fort Collins is a great spot for a weekend trip in Colorado. The historic college town is artsy and vibrant with plenty to do. Whether it’s bringing the kids to the Museum of Discovery, hiking and kayaking at Horsetooth Open Space, perusing Old Town shops, or biking to Fort Collins’ many craft breweries, there’s something for everyone.
For dinner, award-winning Trecento Quindici simply can't be beat. Food is mouthwatering and service is impressive; you can even expect a "crumber" to keep the crumbs from building up on the white tablecloths. The food here is exquisite. It's contemporary, handmade Italian (can you say "Lady and the Tramp?"). Dine in tall, dramatic chairs and feel like royalty.
Beaver Mountain Loop, also used by horseback riders, passes through forests and meadows, crosses Beaver Brook and several aspen-filled drainages, and has a great view of Longs Peak.[42] Deer Mountain Trail gives a 360 degree view of eastern part of the park. The summit plateau of Deer Mountain offers expansive views of the Continental Divide. During the winter, the lower trail generally has little snow, though packed and drifted snow are to be expected on the switchbacks. Snow cover on the summit may be three to five feet deep, requiring the use of snowshoes or skis.[42] 
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.
