Harpers Corner Trail Stop 13

in Colorado

Trees respond to many environmental influences – some so subtle that we may hardly notice them. You might see some trees that are taller than the piñons and junipers you have been walking through. They also have spruce like needles and dangling, thin-scaled cones.

These are Douglas fir, important timber trees in the Pacific Northwest, and common in the high Uinta Mountains, but almost out of their range here. They require a bit more moisture and cooler temperatures than other trees in the area. North-facing slopes, like these around Harpers Corner, receive slightly less sunlight, and more moisture which apparently makes just enough difference for Douglas firs to live here.

Plan your hike

Practical notes

Maps + permits: long-distance trails like this often require permits for through-hiking, backcountry camping, or specific sections (especially in National Parks). Check with the maintaining organisation listed above and the relevant land manager before booking travel.

Water + supplies: water sources vary seasonally on most U.S. trails. Carry a filter and consult current trail-condition reports — through-hiker journals (PCT-L, AT Reddit, etc.) and the maintaining organisation publish regular updates.

When to go: hiking seasons vary widely with elevation, latitude, and snowpack. Through-hikers traditionally start the AT in March-April (Springer northbound) and the PCT in late April (Campo northbound). High-elevation western trails (CDT, JMT, Wonderland) generally aren't passable until July.
