The Pinnell Mountain trail, for me at least, was easier than the Chena Dome outing, because the elevation gains are less overall (the start at Eagle Summit is at 3600 feet, and the highest point, Mt. Pinnell is 4934 ft), and the ascents and descents on the steeper slopes are all switchbacked. Thus, I was able to complete the 27.3 miles of it in nine and a half hours, under beautiful sunny skies, in a stiff 15-25 mph cool (40-45 degrees) northeast wind. I kept to a brisk hiking pace the whole route, and just took four short breaks for food/water, and energy drinks, of 5 to 15 minutes each. I did slow down and take pictures at times too. One highlight of the trail was when I descended into the “Swamp Saddle” between miles 14 and 15. There in that marshy saddle were a herd of caribou. I stopped and stayed quiet, and they actually approached me slightly. But when I said hello to them and they realized what I was, they took off running. This section of the trail, through the swamp saddle, is boardwalked, to protect the marshy tundra, and to make for easier footing. There are also some sections of boardwalk in the last mile before you reach 12 Mile Summit. These can be very slippery when wet or frosty, so caution is advised if that occurs.
The fall colors of the tundra were in full view, and this combined with the clear blue skies and craggy rocks, was stunning. Views north across the Yukon Flats and south through the seemingly endless uplands were a patchwork of brown tundra and fall color dropping down to the spruce and yellowing birch/aspen in the lower elevations.
The 20 mile return bike-ride from trails-end at 12-Mile Summit to my vehicle at Eagle Summit took just under two hours. It proved to be quite fun the first 10 miles downhill, slightly invigorating on the next five mile flat section, and highly challenging the last five uphill miles. A stiff headwind and falling temperatures in the 30s, combined with my overall fatigue from the long day of movement, made that quite memorable as I longed for Eagle Summit to come into view in the fading daylight while my feet began freezing (I had extra layers, but just didn’t want to stop). I had started the day at Eagle Summit at around 10 a.m., and it was near 10 p.m. when I returned to the sanctuary of my vehicle, heat, and warm, dry clothing. Like Chena Dome, Pinnell Mountain Trail is not very heavily used, especially well in from either trailhead. Hence, on the Friday before Labor Day, during my outing, I did not see a single person at any time. And, there are a few sections where the thin, rocky trail disappears and you just navigate to the next cairn or pylon in sight.
