Scramble: RT 9.0; 5.0 up. Mount Decoeli stands out as you drive into Haines Junction with its distinctive pyramidal shape. The objective is a well-worth outing despite lacking a trail. Reaching the summit is straightforward; it requires hiking to the head of a drainage, then ascending steep, grassy slopes to the alpine terrain. The only challenge may be negotiating numerous creek crossings and rushing water along the 5-kilometer-long creekbed in late spring; this could complicate travel, resulting in searching the banks' bushes for trail segments. We had no such challenge in September; we followed the path of least resistance in the creekbed. It took us 2 hours to reach the head of the drainage, where the massive moraines come down the mountainsides. After a brief break due to the nagging wind, we started the ascent. There is a trail at first; however, it fades after a short distance, and random hiking ensues. Climbing the grassy slopes was a welcome change from travel in the creek's rubble. Higher up, grasses gave way to talus slopes. Nearing the summit block, the climb becomes arduous as the terrain gets increasingly looser, but every time you pause, the rewarding surrounding views are an encouragement to continue. Once atop, we were surprised by the absence of wind; how could this be when it was windy elsewhere? It was so delightful to be there with those conditions; we stayed for as long as we could, watching the sun set over the glaciated peaks of Kluane National Park. It was difficult to peel ourselves off the warm summit and begin the descent towards the drainage, already in the shade. When we did, we barely stopped as we raced to get to the car before dark. The descent to the creekbed was fast, but the rest seemed to drag. The temperature was dropping quickly, as I remember my hands freezing. Dusk was upon us when we reached the ATV road that leads to the side of the highway. We made it back to the car just in time. We were pleased with this great day in the mountains. Our visit to Haines Junction was way too short; we're looking forward to returning. Perhaps we will climb neighboring Mount Archibald, which is such a stunning mountain.
