There was a time that John (the baptizer) was baptizing in the vicinity of Aenon near to Salem. I have not had the opportunity to visit the site of Aenon, but I have been to Salem several times. Sergio and Rhoda (locate on YouTube) visited the site with Danny the Digger, a guide who who has lived in the vicinity.
Salem is now identified with Tel Shalim. a site about eight miles south of Beth-shan (Beit She’an) on a dirt road between highway 90 and the Jordan River. In the vicinity there are many pools of water, many now used to raise the fish sold in the restaurants around the Sea of Galilee.

Do the Scriptures really give us a specific location on the Jordan where John baptized?
