Today the Yakima Skyline trail running race was going on, but they were kind enough to not use any of the parking closest to the trailhead. Our hike didn't use the same trails as the race, so we never had to deal with the runners. If you look across the way from the trailhead, you can see that obvious trail that goes up the hill on the north side of the Umtanum Canyon mouth. We crossed the bridge, and then the railroad bridge across the creek, and then headed up that trail. The trail starts fairly steep and then gets to a section that is nearly vertical! It is so steep, the trail is nearly impossible to hike on because of how loose it is, and we had to hike off to the side of the trail. Just above that section, there appears to be a bit of a T in the trail, and we went left staying on what is more of the main trail. As we got higher closer to the top of the ridge, the flowers started to get really good, with great balsamroot, lupine, phlox, and more.
As the trail leveled out, it reached an old road track, and here we turned right (north) and followed it until there was a split, and took the trail that went to the right to stay closer to the canyon. This trail would become a bit more faint and more of a game path, but it was still easy enough to follow and it eventually led to an overlook with some huge tall rock cairns built by people. We then continued on to the top of the hill that overlooks the Beaver Tail, but we didn't hike down onto the peninsula. We did see some bighorn sheep, though. We turned around here and hiked back the same way. Going down the very steep section was a bit rough, but we slowly and carefully got down, staying off to the side of the trail where the footing was better. When we returned to the parking lot, runners were coming through arriving at the finish line.
