I spent a long weekend in Glenwood Springs, Colorado visiting my brother. Happily I got to see some wildlife and habitat from alpine meadows of the Western Rockies to the high mountain desert of National Monument.

Aspens at Maroon Bells
While the fall color is coming late to Seattle this year, there were entire stands of Aspens at higher elevations that had already dropped their leaves. I have read about Aspens in their fall color but never about the trees in winter. They are astonishingly beautiful in a way that is very alien to someone who has lived in the Northeast and then the Northwest. Row upon row of perfectly parallel trunks, all the same color like the bristles of a brush. Only at the tops, where there is a real density of branches arching away from the trunks, do they blur into a furry masses like fur brushed off some great sled dog.
On the southern and eastern sides of the hills, mountains and plateaus the aspen form large groves or are mixed with conifers. On the northern sides, where in the winter the sun penetrates for only a few hours at most, there are thicker stands of pines. The ground plants are, in early fall, mostly brown and dry as are the grasses.
Up on the mountains the forests are bisected by flows of rocks and flows of water in about equal proportions. As impressive as the rock falls are, frightening swaths of boulders, you can still find places where their path is diverted to one side or the other by one unyielding tree. At the higher elevations the rocks echoed the chittering of pikas scurrying about as they prepare their winter dens.
There was a thin blanket of snow beneath the trees on a particularly steep north facing slope and deer tracks crossed from the nearly emptied crater lake into the trees.
The most prevalent bird was the magpie. Almost as ubiquitous as the crows are in Seattle, they were everywhere in town, always in pairs. Though similar in size to crows they are very differently colored and possess a longer and narrower tail. Despite that, when walking on the ground, their movement is similar to that of crows, staulking about purposefully and they have the same tendency to stay on the ground until forced into flight.
When I see hawks in the city they are either perched or soaring high above. All the ones I saw in Colorado were flying down near the ground. They would fly for a distance just ten to twenty feet above the vegetation and then swoop down to hug the top of the tall grass perhaps following some small creature trying to reach the safety of their den.
I finally got to see ravens. We were up on Grand Mesa at a lookout called Lands End [very different from the place with the same name in Cornwall!]. There was a thermal just off the cliff and dozens of ravens were coming in from below and riding to it’s end high over the cliff. A great spiral of black birds rose up to the top where they peeled off, two-by-two, to chase each other out and down to pick up the ride again. They are almost as vocal as crows but the sound they make is throaty and not as harsh.
We didn’t see any elk but we did see a pair of white-tailed deer at the side of the road driving back down from the top of Grand Mesa. Shortly after I spotted a buck on a slope below the side of the road looking over his shoulder at our car as it went by. We also saw a moose at the far side of a road-side field when we stopped to investigate why another driver had stopped.
All of those sightings were in the alpine areas. When we visited the National Monument the wildlife was more limited just as the plants were fewer and further apart. I spotted small lizards twice. Both times I saw them moving fast out of the corner of my eye. Each froze when I turned to look their way and stayed perfectly still while I examined them.
The only other living creature we saw in the desert was a small bird tapping away inside the gnarled remain of juniper trunk. Even the signs of life were few. Down in a slot between the rocks there was a bird’s nest, affixed to a tiny ledge in the wall over our heads. Beneath one pinyon, a cone had been partially pulled apart, presumably by a jay extracting the seeds.

Dead Juniper at National Monument
There are several reasons why there is less vegetation and wildlife than here on the western side of the Cascade Mountains. Less water is the big one. Another reason made itself evident on my last day there when it began to snow in Aspen. At the higher elevations, winter comes sooner and lasts longer resulting in a shorter growing season and more difficulty obtaining food in the winter.
