Greyrock Trail Loop, Poudre Canyon, Colorado
And now for a few more photos from before winter roared back into Colorado this past week:
Earlier this winter we took a day trip up Poudre Canyon, about a half hour northwest of Fort Collins. One of the more popular trails here is a ~5.5 mile loop combining the Greyrock Trail and the Greyrock Meadows Trail. A short spur trail heads up to the summit of Greyrock Mountain (pictured above) near the apex of the loop but we opted to pass on this route due to icy conditions and dwindling daylight. Despite ranging in elevation from 5,500-7,000 feet, the trail was surprisingly snow free, save for the lower sections that were well-shaded by the canyon walls.
The highlight of the hike is most certainly the spectacular granitic rock formations surrounding Greyrock Mountain. I say granitic because the rock here is actually not granite but what geologists call quartz monzonite; essentially granite with slightly less quartz and slightly more feldspar (hence the pinkish color). A seemingly trivial difference perhaps but an important one to geologists trying to unravel the history of the rocks. The steep, smooth faces of Greyrock Mountain wouldn’t look out of place amongst the granite domes of Yosemite National Park. There’s also some good sized pegmatite dikes that criss-cross the area. We found some very large and attractive quartz and feldspar crystals poking around the meadows that surround Greyrock Mountain.
On a non-geology note, the trails winds through several different burn scars, apparently of different ages based on the amount of regrowth in different areas. Many of these burned areas are likely due to the High Park Fire of 2012, one of the largest wildfires in Colorado’s history which ravaged the lower sections of Poudre Canyon. There had apparently been a large windstorm here recently, as there were numerous downed trees, some dead snags but some still very much green and alive, strewn across the trail:
On the hike back down to the trailhead (on the Greyrock Meadows Trail), we were treated to a spectacular sunset over Poudre Canyon as well as views of the distant Mummy Range in Rocky Mountain National Park.
Great shot =)

Nice post. I’ve gotta get up there again soon-looks like things are going to warm up a bit for next week!
