This is the Peacock Loop, sometimes just called "The Peacock." Relatively easy, rolling loop out of the Margaret McKenny Trail Head. The route can be ridden either direction although it's most commonly ridden counter-clockwise. For a slightly longer route, you can ride out of the Mima Trailhead and use the Mima Falls East trail to get to the main loop.
Large tree down across trail (8" diameter), blocking trail right before the intersection of Lost Valley when headed down the hill towards Fall Creek. Moist ground with a few muddy puddles. The worse puddles seemed to be on the first half to the intersection with Mima Trail/Lost Valley in the opening. That tree at 45° on the ground is about 1/3 of the way along the trail. It can be rode around but should be removed as could be a hazard if coming downhill and not looking far enough ahead or if it's dark.
