Above tree line, at approximately 11,000 ft (3,400 m), trees disappear and the vast alpine tundra takes over.[69] Over one third of the park resides above the tree line, an area which limits plant growth due to the cold climate and strong winds. The few plants that can survive under such extreme conditions are mostly perennials. Many alpine plants are dwarfed at high elevations, though their occasional blossoms may be full-sized.[73]

Black Canyon of the Gunnison is a fabulous, rugged looking canyon, and it's remote enough that it has the feeling of being undiscovered. Steep cliff walls rise up from the Gunnison River, creating a narrow and dramatic canyon. The depth of the canyon is around 2,000 feet, with Gunnison Point and Chasm View at just over 1,800 feet and Warner Point at 2,722 feet.
Thanks to a wide variety of things to do and places to see, Boulder is arguably one of the best weekend getaways in Colorado—if not the whole Western United States! This college town (home to University of Colorado Boulder) has it all: hike the Flatirons or Chautauqua Park in the morning, tour the Celestial Seasonings Tea Factory and Leanin’ Tree gallery in the afternoon, and then head to Pearl Street for shopping, drinking, and dining at night—and get around on the Boulder Creek Path in between. A Boulder bike tour helps you fit in even more sightseeing, perfect for a quick itinerary.
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.
