from the NPS site: tilted rocks of the Sinking Ship impart an impression of geologic unrest to viewers, and rightly so. These rocks are a reminder of the tectonic activity that began 15 million years ago, raising the Paunsaugunt Plateau to its present elevation and dragging sections of rock along the faults, resulting in the tilt we see today. Earthquakes in recent years remind us that Earth is constantly adjusting and that activity along those faults continues, although in relatively minor magnitudes.
