    // Clone Features to west and east. For each feature...

    for(const feature of myFeatures) {

      // Check if feature or feature.geometry is null or undefined

      if(!feature || !feature.geometry){

        console.warn("Invalid feature or missing geometry: ", feature);

        continue;

      }

      // Clone it

      let westCopy = structuredClone(feature);

      let eastCopy = structuredClone(feature);
