4.7 miles up the Lake Fork trail, we crossed the nice wide wooden bridge, where I took this picture of Thunder Mountain. We met a couple here who had done a day hike. This was our last human encounter for the next 26 hours.
We were heading for Keyser Brown Lake, which lies on the other side of this mountain. We also hoped to explore First Rock and Second Rock Lakes further up the canyon beyond Keyser Brown. At this point, the trail became a bit steeper, but it was not bad.
