Sailing stones
Sailing stones, sliding rocks, and moving rocks all refer to a geological phenomenon where rocks move and inscribe long tracks along a smooth valley floor without human or animal intervention.
The stones move only every two or three years and most tracks develop over three or four years. Stones with rough bottoms leave straight striated tracks while those with smooth bottoms tend to wander. Stones sometimes turn over, exposing another edge to the ground and leaving a different track in the stone's wake.

In the mid-1950s, the wooden stairs were replaced by sections of metal steps and ramps — by one count, 4000 steps. The station and trail were closed to the public in 1987. Some hikers ignore the No Trespassing signs and continue to climb, contributing to the local community's misgivings about reopening the structure.
