According to our map, the trail would run relatively straight down the mountain until we would reach a large river. We figured there would be a campsite there and planned to quit early. Oddly, the trail just kept going and going. I tried to get a better idea of where we were, but because of the thick forest we couldn't really see where we were and my InReach Mini GPS had surprisingly poor reception in the valleys and forests - even though it had been working great during my 2019 Greenland trip. It took over an hour longer than expected to reach the river and a huge bridge. We figured we had been walking slower than expected because of all the fallen trees and our map might not depict all the switchbacks. We definitely hadn't succeeded in stopping early, but at least it was still light out. Some hikers told us the next campsite was another 3-4 km away and uphill, so we called it a day. While we were setting up camp several PCT hikers walked by. They all seemed to be traveling from sunrise at about 6:00 to just before sunset at 20:00. Around 19:00 a couple came down to our campsite below the bridge to fetch water, but they decided not to camp yet. I think many of the thru-hikers often just camp on the trail itself.
