The ancient Three Room Ruin is located in Road House Canyon. The trail leading to the ruin is accessible by Cigarette Springs Road. The ruin is sometimes called Road House Ruin or Falling Roof Ruin.
Sheets of sandstone above the Three Room Ruin have been falling for centuries, revealing a spectacular dome-like ceiling. Luckily the falling rock has not damaged the ruin. It’s possible that the structure helps to support the otherwise unstable pieces that sit directly above it.
