After exploring the Citadel ruin at the top of Road Canyon, we ventured down into the canyon then up the south face to visit Fallen Roof ruin. The name should be obvious from the photo above: the recess cave roof is collapsing, not the dwelling itself. Not an archaeologist but it is apparent that the roof was falling while still occupied.
The pictographs above are good evidence for why you should linger and observe while visiting these ruins. Neither of us noticed them until we were about to leave.
What inspired these images? Is it mere graffiti or was it done as a reward? Capture of family history?
