These obelisk-like glacial residues are a hallmark of Zuort.

In the course of the last ice age, from about 80,000 to 10,000 years ago, the two glaciers of Val Laver and Val Chöglias melted, their tongues joining just below Zuort. What remained were two glacial debris moraines, exposed to the climate and thus to erosion. Chunks of 50-million-year-old granite or serpentine weighing tons were transported downhill by the ice to the glacier tongues. After it melted, the moraines beneath these boulders were protected from erosion: this is how high pointed debris cones of up to 15 metres in height were formed with their respective boulder as a cap weighing several tonnes. The local name for these towers of moraine debris is ils Cluchers (phonetically: klutchears), the church towers of Zuort.
