We need some desert anon to set up a cheap web cam for six months or so out in the desert and see how well the lens holds up.
Looks like Ireland is the winner.
Karstic landscape in the Burren
This part not in the link
[The Burren is a region of County Clare in the southwest of Ireland. It’s a karst landscape of bedrock incorporating a vast cracked pavement of glacial-era limestone, with cliffs and caves, fossils, rock formations and archaeological sites. On the Atlantic coast, the precipitous Cliffs of Moher are home to thousands of seabirds, including puffins. Nearby Doolin village is a renowned centre for traditional Irish music.]
