It's been a very wet day today here. Swallows amazingly came in during a brief lull in the weather. It's a good opportunity to catch up with the rest of the weekend. On Saturday we were in Huelva for a regional meeting of the Quaternary Association (AEQUA). We've belonged to this group for 16 years now and their field meetings (twice a year) are well worth going to as they are held in special places around the southern Iberian Peninsula and they bring together experts who talk about the sites being visited: geologists, ecologists, palaeontologists, archaeologists, geographers and historians. This meeting focused on the very interesting 12-kilometre long Nueva Umbria sand spit.
