Cut pebbles in tuff show ruts postdate hardening; quarrying theory proposed

Key facts
- Basalt pebbles embedded in the tuff were cut clean through by the rut edges.
- This indicates that the tuff had already hardened when the ruts were carved.
- A listener proposed that the ruts could be quarrying marks made with large twin-drum mining machines; this remains the listener's hypothesis.
- Clapham Junction, officially Misrah Għar il-Kbir, is a famous Maltese site with a complex network of converging cart ruts.
- The site's age and purpose remain debated; its layout has not been established as a quarrying pattern.
- Contributor Mike, known as Wandering Wolf, reported associating Malta's ruts with quarrying routes and said he had observed ruts in China.
- Mike contrasted the more orderly layout at Clapham Junction with the more haphazard appearance of the Turkish ruts; this is his interpretation.
