Hiked the entire length of this trail with OliverPhineas (OP/original poster), but leaving report mileage at 0 to track mileage in the Summerson - Trout Ridge - Lock Branch Loop trail. The blazes along the John Summerson Trail are difficult to follow, even in the beginning where it splits with the Lock Branch Trail near the campsites 0.2 miles in from the parking area. We found a neat rock outcropping on the spine of the mountain, which we nicknamed "Hemlock Rock" on this hike. Also found a series of small waterfall cascades in the 2nd half of the trail. Hikers should note there is one very steep and potentially dangerous section of trail around mile 1.3 where the terrain becomes extremely narrow and slopes at a very steep grade. Last to note - if you hike this as an out-and-back, it might make sense to hike off-trail through the valley below along the creek to avoid the steep slopes - as OliverPhineas did in this trail data.
Beautiful day for a hike on a short trip back to Pittsburgh. This spot is one of my favorite places to kill time while getting a nice view of the city. Hiked down to almost the opposite end of the island before turning back.
Came back to explore the old quarry site, millstone, and the swampy area just west of the old quarry. Neat little spot for a super short walk if you just want to check out the old quarry and millstone.
Took a short walk out to the graffiti bridge to find the recent rainfall and snow melt had washed debris and dirt onto the bridge. Most of the graffiti, including the Rick, is now under about an inch of dirt.
Came back to try and reach Upper Miners Falls, but did not realize how difficult it was to get to. Middle Miners Falls seemed good enough for me and my small dog for this trek.
Second trip back to this trail since I missed Jacoby Falls the first time when I stopped at the unnamed waterfall. As the snow melts, the trail becomes even more icy, so ice spikes and trekking poles are smart for end-of-winter hikes here. This trail is very empty during weekday mornings in the winter as well.
Came back to conquer the traverse upstream to Lower Fall Brook Falls during the winter in the snow; however, I would not recommend anyone but experienced hikers (and dummies) to attempt this hike to the frozen waterfall. Hikers will need, at least, ice spikes and trekking poles, to navigate the very deep and unexpected holes/caveties under the snow and within the rocks and boulders as they hike upstream. There are plenty of places where, if you slip, you can fall several feet or more into freezing creek beds, which can be about 2-feet deep. Super dope spot for the winter though, if you can safely make it up the creek. Hike at your own risk.
Winter hike out to Neslon Falls. Trail is easy to hike with ice spikes. Waterfall did not have much buildup of ice but was still nice to visit. Parking is street-side since the lot is not cleared in the winter.
