Although the fort itself is small, Yotvata is really an interesting site and has yielded quite a few pottery vessels from several occuptaion periods that have been nicely reconstructed. There is an article about the site in the "Journal of Roman Archaeology" Vol. 17 (2004) that is written by the directors of the excavation. I'll be heading back there in mid June to continue my work and will also be taking another trip to Petra in Jordan this year. I'll keep you posted as far as the website goes- I'll need permission from excavation directors to post photos/drawings.
