Are there weight restrictions for the ladders in anasazi ruins?
Which Anasazi ruins are you talking about? Most of the restored Anasazi ruins that people visit are pueblos ruins where you typically walk along the edge of the ruin or through a few rooms on a specific footpath (with markers along the way) without having to go up or down any ladders. There are a few places where they have a restored underground kiva room that you can climb down a ladder into (such as at Pecos and Bandelier) and a few other places where you can climb up ladders to reach cliff dwellings (Bandelier, Mesa Verde, Gila National Monument). In all of these cases, the ladders are recently built modern ladders, not the original prehistoric ladders. Sometimes they are plain modern ladders made of cut wood beams and in other cases they are made of logs to resemble the old ones. In either case, all the ones that I have seen are pretty sturdy. I have never seen a weight limit posted next to them, but I would guess most could hold a 300 pound person at least.
